Updated October 15, 2026. Every published price below was read on the vendor's own pricing page that day; quote-only tools are labeled as quote only.
The best data enrichment tools in 2026 are Clay and BetterContact for waterfall enrichment, ZoomInfo, Apollo.io, Cognism, Lusha, HubSpot Breeze and People Data Labs for single-source contact data, and 6sense, Demandbase, Crunchbase and BuiltWith for account signals. Architecture decides the result more than the brand: one provider usually matches about 60 to 70% of a list, while a waterfall that asks several providers in turn takes the same list into the 90s.
Key Findings
- Twelve data enrichment tools compared on architecture, published price, coverage and the trade-off you feel after signing.
- A waterfall beats a bigger database. Querying one provider leaves roughly a third of a list unmatched; three providers in sequence reach 90% or more and only charge for the hit.
- Entry prices read on October 15, 2026 run from $15 a month (BetterContact Starter) to $295 a month (BuiltWith Basic). ZoomInfo, Cognism, 6sense and Demandbase publish no price.
- Contact data, company context and timing signals are three separate jobs. Most working stacks pair one contact source, one waterfall layer and one signal source.
- Reachly runs Clay as the spine with Icypeas, Prospeo and BetterContact in the waterfall, and the same stack is laid out on the outbound tools page.
- Score vendors on 500 rows of your own ICP before a demo with the 12-point scorecard below.
- If the goal is booked meetings rather than a cleaner CRM, Reachly runs enrichment inside its outbound lead generation services.

| Demandbase | ABM orchestration and account data | Intent and signal layer | Quote only |
| Crunchbase | Funding and company intelligence | Curated company dataset | $49 a month billed yearly |
| BuiltWith | Technographics | Web-crawl dataset | $295 a month |
What is a data enrichment tool?
A data enrichment tool appends verified attributes to records you already hold. You give it an email, a domain, or a name and company; it returns the fields that make the record sellable: work email, direct dial, job title, headcount, revenue band, tech stack, funding history, and in the better tools, buying signals such as hiring or tool changes.
Three things separate an enrichment platform from a list vendor. It runs continuously rather than as a one-off append, it writes back into your CRM instead of exporting a CSV, and it tells you how each value was verified and when. A vendor that cannot say where an email came from is selling a list. The wider category mechanics are in our guide to B2B data enrichment, and the vendors that sell the raw contact database are compared in the best B2B data providers.
What are the three data enrichment architectures?
Every tool on this list uses one of three approaches, and this is the single most useful lens for evaluating them.
| Architecture | How it works | Typical match rate | Where it breaks |
|---|---|---|---|
| Waterfall | Providers queried in sequence until one returns a verified value | 90%+ | Credit spend climbs on wide waterfalls, and it needs an operator to configure |
| Single source | One vendor owns the database and answers every lookup | 60 to 70% | Niche verticals, non-US regions, and records that aged since the last refresh |
| Account signals | Intent, funding or technographic data attached to the account | Not a contact source | Tells you who to work first, then needs a contact tool beside it |
A single-source tool with a huge database still verifies a record against only itself, so a stale record verifies as valid.
The practical consequence: a single-source tool is judged on how good its one database is, and a waterfall is judged on how well it is configured. If nobody on your team will own the configuration, a waterfall becomes an expensive way to get single-source results.
How did we evaluate these data enrichment tools?
Four criteria, in the order they affect outcomes.
- Verification method. How a value is confirmed, and against how many independent sources. This drives bounce rate, which drives domain health.
- Coverage where you sell. Aggregate database size is close to meaningless. Coverage in your segment and region is the number that matters.
- Operational fit. Native CRM sync, refresh cadence, and whether the tool surfaces changes fast enough for a rep to act on them.
- Real cost per usable record. Sticker price divided by records you can actually send to, which is a larger number than the price per credit.
We weight verification first because it is the one failure that compounds. A bad list costs you one campaign. A domain flagged by sustained bounces costs you every campaign after it, as covered in our email deliverability guide.
The stack Reachly runs
Reachly is a Clay certified partner, and Clay is the spine of the stack it runs for clients: it holds the list, runs the waterfall and scores each account. Behind it sits a waterfall of Icypeas, Prospeo and BetterContact for contact data, because no single provider covers a full list. Querying one provider and accepting the misses produces a match rate around 60%. Querying three in sequence and paying only for the hit takes the same list into the 90s, at a lower cost per verified contact. The full stack, layer by layer, is on the outbound tools page.
How accurate is enriched B2B data in practice?
Vendor accuracy claims are self-reported, and every comparison guide written by a vendor puts that vendor first. These are our own numbers, from 47 campaigns where we ran single-source and waterfall enrichment side by side before dropping single-source from the sourcing layer in 2025.
| Metric | Single-source enrichment | Waterfall enrichment |
|---|---|---|
| Measured email accuracy | 65 to 90% | Above 95% |
| Bounce rate on send | 5 to 10% | Under 3% |
| Campaigns missing a sub-3% bounce target | 41 of 47 | Fewer than 1 in 20 |
| Independent sources checked per record | 1 | Up to 8 |
| List decay over a year | 3% bounce in March became 8 to 11% in December on the same saved filter | Re-verified on every run |
Reachly campaign data, 2022 to 2024, across SaaS, fintech, agency and APAC ICPs. The single-source column is Apollo-sourced; the waterfall column is Clay-verified. Full breakdown in Clay vs Apollo.
Two findings worth carrying into any vendor conversation. Accuracy degrades on a calendar, so ask when a record was last verified rather than how many records exist. And verification against a single database is circular: when the record is wrong, the verification is wrong with it, which is why the waterfall column holds a 95% floor.
1. Clay, waterfall enrichment and workflows
Clay owns no database of its own. It pulls from more than 150 data providers, runs waterfall logic so one provider covers for the misses of another, appends buying signals, and uses its AI agent, Claygent, to research each account. Then it pushes the enriched rows to your CRM or sender.
That makes it the tool most teams mean when they say waterfall enrichment, and the one the three top-ranking roundups for this search all include.
Where Clay fits
RevOps teams and agencies that run signal-based outbound, sell into niches where one database runs thin, or need custom fields no vendor sells. Clay is the spine of the stack Reachly runs for clients, with a waterfall of contact providers behind it.
The trade-offs
The power lives in tables you have to build, and a first working waterfall takes most operators two or three days. Credits burn faster than new users expect on wide waterfalls. Clay also only enriches what you point it at, so a sloppy seed list still produces sloppy output.
Pricing
Free plan with 1,200 data credits a year. Launch starts at $167 a month billed yearly ($185 monthly), Growth at $446 a month, with unlimited seats on every plan. Read on Clay's pricing page October 15, 2026.
Tool site: Clay
2. BetterContact, pay-per-hit waterfall
BetterContact is a waterfall you buy ready-made. It routes each lookup across more than 20 email and phone providers, validates the result, and only charges when it returns a valid email or mobile number.
Where Clay asks you to design the waterfall, BetterContact runs one for you. It also plugs into Clay as a single step, which is how it sits in the Reachly stack.
Where BetterContact fits
Teams that want waterfall match rates on emails and mobiles without building tables. It suits SDR teams that call, because it scores each mobile number by its likelihood to connect and charges only for the high-propensity ones.
The trade-offs
It enriches contacts and stops there. There is no account scoring, signal logic or workflow layer, so teams running signal-based campaigns still need Clay or a signal source beside it.
Pricing
Starter is $15 a month for 200 credits, Pro starts at $49 a month for 1,000 credits, and Enterprise starts at $799 a month. One credit covers a valid email; a mobile costs ten. Read on BetterContact's pricing page October 15, 2026.
Tool site: BetterContact
3. ZoomInfo, OperationsOS (Enrich and DaaS)
ZoomInfo is the tool big teams buy when enrichment stops being a rep problem and becomes an operations problem. If you need one system that feeds sales, RevOps, routing, scoring and CRM hygiene at the same time, it belongs on the shortlist.
ZoomInfo positions its platform around a very large B2B database plus an operating layer for go-to-market teams. You pay for contact data and also for workflow control, integrations, and the ability to push data across systems cleanly.
Where ZoomInfo fits
ZoomInfo works best in mature setups: Salesforce with strict field rules, HubSpot tied to lifecycle automation, a warehouse in the background, and ownership, routing and suppression rules already written down. If that is your world, ZoomInfo usually fits better than lighter tools.
It is one of the few options a RevOps team can own long term. The bigger value is operational: enrich records, standardize data, sync fields and keep systems aligned without exports and manual cleanup. For the process side, our guide to B2B data enrichment workflows and field strategy is a useful companion to any ZoomInfo evaluation.
The trade-offs buyers feel after the contract is signed
ZoomInfo is strong on breadth, especially for US-based teams, with the connector depth larger orgs need.
The harder part is cost discipline. Contracts are annual and can be rigid, and teams overestimate how much of the platform they will use before their CRM, routing and ownership rules are clean. Use ZoomInfo with scale, admin support and a real ops function. For affordable contact enrichment and basic prospecting, you would be paying enterprise prices for capabilities you will leave idle. Our ZoomInfo alternatives guide covers the cheaper routes.
Tool site: ZoomInfo
4. HubSpot Breeze Intelligence (formerly Clearbit)
If you live in HubSpot, Clearbit, now sold as HubSpot Breeze Intelligence, is the easy answer for HubSpot teams specifically.
Teams buy it because setup feels painless. It pays off most when your CRM, workflows, forms and reporting already run through HubSpot.
Why HubSpot teams keep choosing it
Breeze Intelligence keeps enrichment where your team already works. New leads come in, records fill out, workflows trigger, segmentation gets cleaner, with no exports in between.
You can run real-time and bulk enrichment inside HubSpot itself, and that matters more than feature breadth. When enrichment is native to the CRM, reps use it.
Where it falls short
Outside HubSpot, the value drops fast. Credit models are harder to compare, and if your team needs contact-level depth rather than company-level context, you may end up pairing it with something else anyway. If HubSpot is your home base, it is a practical buy. If it is not, skip it.
Tool site: HubSpot Breeze Intelligence
5. Apollo.io, enrichment plus sending
Apollo sells because it replaces a pile of tools with one login.
For a startup or lean sales team, that matters more than a pristine feature comparison. You can prospect, enrich records, sync to the CRM and run outreach without stitching together four vendors and four invoices.
Why Apollo gets bought
Apollo positions itself as a large B2B database plus outbound workflow software, and the value is in that bundle. Teams buy it to source contacts, fill missing fields, launch sequences and keep moving without a more complex stack. That makes it attractive for founder-led sales, early SDR pods and agencies with smaller clients. Our guide to B2B lead generation tools compares it with other combined sourcing and sending tools.
Where Apollo starts to hurt
Apollo is strongest when budget and speed matter most, and weaker when data quality is the problem you are solving. In our own campaigns, Apollo-sourced lists bounced at 5 to 10% before verification, which is why we run a waterfall layer behind it.
The subscription looks cheaper up front, then your team spends time cleaning records and verifying emails that a waterfall would catch earlier. Buy Apollo for one platform that does a lot reasonably well. If precision matters, pair it with a verification layer.
Pricing
Free plan, then $49, $79 and $119 per seat a month billed yearly, read on Apollo's pricing page October 15, 2026.
Tool site: Apollo.io
6. Cognism, sales intelligence with Diamond Data
If your team calls into Europe, Cognism deserves serious attention. Many US-first tools look fine in demos, then thin out the moment you push into EMEA.
Cognism's edge is mobile numbers and compliance, especially across borders.
Best use case
This is a calling tool as much as an enrichment tool. The Diamond Data positioning is built around human-verified mobile numbers, which tells you who it is for: SDR managers who need reps speaking to people. If your team sells into Europe, buying the wrong data vendor creates compliance pain fast.
How it stacks up
In a 2026 comparative review, Cognism scored 23 out of 30 for Data and Lead Generation, behind ZoomInfo at 24 in the same review. What matters more is fit: Cognism is a better answer for EMEA-heavy, phone-led outbound than for general-purpose, low-cost enrichment, and the annual contracts feel heavy if you will not use the mobiles.
Tool site: Cognism
7. People Data Labs, person and company enrichment APIs
People Data Labs is for builders. If you want person and company enrichment APIs to wire into your own systems, PDL is one of the more practical choices. If you want a polished rep workflow out of the box, look elsewhere.
Why technical teams like it
PDL gives developers room to work: bulk endpoints, configurable matching, datasets delivered through warehouse-friendly pipes, and solid docs. That matters for custom lead scoring, internal research tooling, or CRM enrichment logic that does not fit a standard sales workflow. It belongs in a different bucket from seat-based prospecting tools.
What to watch
Control moves the work back to your team. You define match rules, handle edge cases, decide overwrite logic and monitor freshness yourself. With a strong data team, that is fine. Without one, PDL turns into a capable tool that nobody operationalizes.
Pricing
Free tier, then from $98 a month for the Pro plan, which starts at 350 credits a month, read October 15, 2026.
Tool site: People Data Labs
8. Lusha, contact and company enrichment
Lusha is the tool reps adopt without asking permission, which is both its strength and its problem.
It is fast, the Chrome workflow is easy, and small teams start using it right away for contact lookups and bulk enrichment, with no RevOps project needed.
Where Lusha works
SMB and mid-market teams that need quick access to emails and phones without buying an enterprise platform. Reps like it because it removes friction; managers like it because onboarding is easy.
Where teams get annoyed
The credit math gets messy in practice, and fast adoption comes with thinner coverage in tougher segments and less operational depth once you standardize usage across a larger team. Buy Lusha as a lightweight rep tool. For CRM decay, territory routing or multi-source logic, it sits outside the center of that system. Our Lusha alternatives guide prices the cheaper options.
Pricing
Free plan with 40 credits a month, then Starter at $37.45, Pro at $52.45 and Premium at $299.95 a month, all billed yearly, read on Lusha's pricing page October 15, 2026.
Tool site: Lusha
9. 6sense, data packs and data cloud
6sense is the right choice when you care about timing more than field completion.
Teams that evaluate enrichment as a better spreadsheet append miss where the category is moving: toward real-time and predictive enrichment, identity resolution, technographic change tracking and behavioral signals, as Zapier's review of data enrichment tools also notes.
Who should buy it
Teams whose motion already uses account prioritization, where the job is "tell me who matters now" rather than "find missing data." Intent and technographic packs turn broad targeting into timely targeting. If you are layering signal-led outreach into your process, our guide to B2B intent data covers how intent changes action.
The trade-off
6sense is stronger on account intelligence than on contact depth, and it will not fix a broken contact layer. Most teams still run a contact source beside it.
Tool site: 6sense
10. Demandbase, sales intelligence and data cloud
Demandbase makes the most sense when sales and marketing work from the same account list. Its value comes from combining account data, scoring and activation in one motion.
Where Demandbase stands out
Firmographics, technographics, intent and account-level activation sit closer together than they do in point tools. That is useful for teams that run ABM seriously, with real coordination between target accounts, ads, sales plays and reporting.
What usually goes wrong
Teams buy Demandbase and then use a fraction of it. Without enough cross-functional usage, the economics are hard to justify. For lean outbound teams that mostly need better contacts and cleaner CRM data, it is too much platform.
Tool site: Demandbase
11. Crunchbase, company intelligence
Crunchbase is a company intelligence and timing-signal tool. Funding activity, investor context and growth signals tell you who to target and when to reach out.
Best use case
Teams selling to startups, venture-backed companies or fast-changing private companies. You enrich account records with context that changes your messaging and your sequence timing, which static fields like industry and size cannot do.
The limit
Crunchbase will not replace a contact database; it sits beside one. Use it when reps need better reasons to reach out rather than more names to reach out to.
Pricing
Pro is $49 a month billed yearly ($99 monthly), and Business starts at $199 a month billed yearly, read October 15, 2026.
Tool site: Crunchbase
12. BuiltWith, technographics enrichment
BuiltWith is easy to justify when your product fits certain tech stacks. If tooling is part of your ICP, technographics stop being optional.
Why it belongs in a modern stack
Contact enrichment tells you who a prospect is. Technographics often tell you whether they are worth your time. If you sell a Shopify app, a security product, a martech integration or anything that plugs into an existing stack, BuiltWith tightens targeting, and its historical change data spots accounts in transition.
What it will not do
BuiltWith is strongest on web-facing technologies and blind to most backend systems and internal SaaS. Treat it as a targeting layer and pair it with a broader company dataset. For tools that only show up on a public page, such as a job post that names the CRM a team uses, an Apify scraper pulls the page into Clay so you can check it yourself.
Pricing
Individual lookups are free. Basic is $295 a month, Pro $495 and Team $995, read October 15, 2026.
Tool site: BuiltWith
How do the top 12 data enrichment tools compare?

| BetterContact | Email and mobile via waterfall | No | No | Via Clay, Zapier, API | Credits, charged on valid results |
| ZoomInfo | Email and direct dial | Deep, with hierarchy | Intent add-on | Yes | Annual contract, quote |
| HubSpot Breeze | Email, limited phone | Strong firmographic | Buyer intent | HubSpot native | HubSpot credits |
| Apollo.io | Email and direct dial | Standard firmographic | Basic filters | Yes | Per seat, credit-capped |
| Cognism | Phone-verified mobile | Good EMEA depth | Limited | Yes | Annual contract, quote |
| People Data Labs | Email via API | Person and company records | No | Build it yourself | Usage-based API |
| Lusha | Email and phone | Basic | Buying intent topics | Yes | Credits, seats on higher tiers |
| 6sense | Thin on contacts | Account-level | Strong intent model | Yes | Annual contract, quote |
| Demandbase | Thin on contacts | Account-level | Strong intent model | Yes | Annual contract, quote |
| Crunchbase | None | Funding and investors | Funding events | Business plan | Subscription |
| BuiltWith | None | Technographics only | Tech install changes | Yes | Subscription |
The last four rows are account-signal tools. Comparing them with ZoomInfo on email coverage misses what they are for.
What do data enrichment tools cost in 2026?
Eight of the twelve publish a price, four sell by quote only, and HubSpot bundles enrichment into its credits. Here is the cheapest paid plan for each tool that publishes one, read on the vendor pages on October 15, 2026.
| Tool | Cheapest paid plan | What it includes | Billing |
|---|---|---|---|
| BetterContact | $15 a month | 200 credits, charged only on valid results | Monthly |
| Lusha | $37.45 a month | 4,800 credits a year, 1 seat | Yearly |
| Apollo.io | $49 per seat a month | 30,000 credits a year per seat | Yearly |
| Crunchbase | $49 a month | Pro, one user | Yearly ($99 monthly) |
| People Data Labs | $98 a month | From 350 credits a month | Monthly or yearly |
| Clay | $167 a month | Launch, 30,000 data credits a year, unlimited seats | Yearly ($185 monthly) |
| BuiltWith | $295 a month | Basic, 2 technology reports | Monthly |
| HubSpot Breeze | HubSpot credits | Bundled into your HubSpot plan | With HubSpot |
| ZoomInfo, Cognism, 6sense, Demandbase | Quote only | Annual platform fee plus seats or data | Annual contract |
Read on each vendor's pricing page on October 15, 2026. Where a tool is quote-only we say so rather than repeat a third-party estimate.
The figure that matters is cost per usable record: what you paid divided by the records you could actually send to. A tool at $0.10 per credit with a 70% match rate costs more per usable record than one at $0.15 with a 95% match rate, and the gap widens once you price in the bounces. Per-email cost for the contact vendors is broken out in the best B2B data providers.
How do you score a data enrichment vendor before you buy?
Every vendor demo runs on the vendor's own best-case list, which is why tools that look identical in a comparison table behave nothing alike on your data. Score them yourself first. Pull 500 rows of your real ICP, include 50 records you have already verified as a control, and run the same rows through every tool on a trial.
The line that decides most of these calls is number 11. Credit pricing hides the number that matters, which is cost per verified contact. A tool at half the credit price with a 55% match rate costs more than one at full price hitting 90%.

RUN IT PROPERLY
- Use the same 500 rows for every vendor.
- Include 50 rows you already have verified data for, as a control.
- Test the weakest region separately or a strong home market hides it.
- Score before the demo. A demo runs on the vendor's best data.
Which data enrichment tool fits your situation?
Buy for the bottleneck you already feel.
| Your bottleneck | Start with | Why |
|---|---|---|
| Emails bouncing above 3% | Clay or BetterContact | Verification against several sources is the structural fix. A bigger database will leave the bounce rate where it is. |
| CRM records half-empty | HubSpot Breeze or ZoomInfo | Native sync and governance matter more than raw coverage here. |
| Outbound live this week on a small budget | Apollo.io | Sourcing and sending in one bill at $49 a seat. Accept the accuracy ceiling as the price of speed. |
| Selling into Europe, phone-led | Cognism | Phone-verified mobile coverage and a GDPR posture built for the region. |
| No idea which accounts to work first | 6sense or Demandbase | This is a prioritization problem, and a contact database leaves it unsolved. See B2B intent data. |
| Engineering team wants to build on it | People Data Labs | Clean API, usage pricing, no interface to fight. |
| Targeting on tech stack | BuiltWith | Technographics is a distinct dataset that general databases cover poorly. |
| Timing plays around funding | Crunchbase | Funding events as a trigger, wired into a sequence. |
| You want the workflow run for you | A done-for-you provider | Covered in the next section. |
When should you hire a data enrichment provider instead of buying a tool?
Hire a data enrichment provider when the bottleneck is the work rather than the data. The tools above hand you a database, a match rate and an API, then leave the waterfall design, the verification logic, the CRM field mapping and the outreach to your team. A provider owns all of that and bills one retainer, which starts around $3,500 a month for a fully managed outbound motion.
Search treats the two as one category. "Data enrichment providers", "data enrichment companies" and "data enrichment vendors" all return a mix of the tools compared above and the agencies that run them for clients. The question that separates them is who owns the maintenance: data sources change, schemas break, and a waterfall that worked in March quietly degrades by December.
Build in-house or hire
Building enrichment in-house wins on control. You get custom scoring, your own routing rules, and one pipeline that can feed product and marketing as well as sales. It costs a RevOps or data engineering owner who keeps the logic current, which is a real headcount line.
Hiring a provider wins on speed. The provider already runs the waterfall across several sources, already holds sending infrastructure warmed and separated from your primary domain, and is measured on booked meetings rather than on records appended. The trade-off is less visibility into the mechanics and a monthly commitment instead of usage-based credits.
| Your situation | Better buy |
|---|---|
| RevOps or a data engineer can own match logic and refresh cadence | A tool from the twelve above |
| Enrichment has to feed product, partner and marketing systems as well as sales | A tool, bought for its API |
| Budget is a few hundred dollars a month | A tool, self-serve tier |
| Nobody owns the waterfall and records go stale between quarters | A provider |
| The enriched record has to become a booked meeting this quarter | A provider |
| You want sending domains, warm-up and reply handling included | A provider |
Score a provider the way you would score a tool, on coverage in your segment, refresh frequency, verification method and compliance posture. Add two questions a tool never has to answer: what the provider does when a campaign underperforms, and who owns the domains and the workspace when the engagement ends.
Reachly sits in the provider column. The team maps the TAM across 10 or more data sources, enriches accounts with buying signals like headcount growth and funding, verifies contacts before anything sends, then runs cold email, LinkedIn and cold calling on top, with reply management and meeting booking included. Sending runs on dedicated domains, warmed for 4 weeks, so the client's primary domain stays clean, and first meetings typically land 2 to 6 weeks after launch. The full scope is on the outbound lead generation services page, and Reachly's data enrichment services cover the enrichment work on its own.
What are the five mistakes that waste an enrichment budget?
- Buying database size. Aggregate record counts are marketing. Coverage in your segment and region is the only number that predicts your results.
- Skipping the verification question. Ask how a value was confirmed and when. A vendor that cannot answer is selling a snapshot of a dataset that has already moved.
- Treating enrichment as one problem. Contact coverage, company intelligence and timing signals are three different jobs. Forcing one vendor to do all three usually produces worse data on all three.
- Buying more data before fixing match logic. If your CRM cannot dedupe or match reliably, new data lands on a broken foundation and the mess compounds.
- Ignoring the sending layer. Clean data sent from a cold domain still lands in spam. Enrichment sets your ceiling; infrastructure decides whether you reach it. See inbox rotation for cold email.
How should you choose a data enrichment tool?
The best data enrichment tool is the one built for your workflow. For a waterfall you control, Clay. For waterfall results without building tables, BetterContact. For enterprise depth and governance, ZoomInfo. If you are all-in on HubSpot, Breeze Intelligence. For prospecting, enrichment and outreach in one place, Apollo. For Europe and mobile data, Cognism. For API-first teams, People Data Labs. When timing and account signals matter more than field completion, 6sense and Demandbase, with Crunchbase and BuiltWith as cheaper signal layers.
Most mature stacks combine them: one contact source, one waterfall layer and one signal source, all writing into the same CRM. That is also the order enrichment takes in the four-step process in Reachly's sales prospecting techniques guide, right after research and list building.
Static append workflows are losing ground to systems that keep records fresh, sync into the CRM and surface changes quickly enough for reps to act. So ask vendors about refresh logic, validation method and operational fit before database size.
If you are benchmarking your own outbound setup against competitors rather than picking tools in isolation, Riff Analytics' benchmarking guide is a useful next read.
We build the waterfall, verify the data, and run the outbound on top of it
Reachly stacks the enrichment providers inside Clay, rotates out any mailbox that bounces above 2%, and runs cold email, LinkedIn and cold calling to book the meeting. For Primal, that produced 85+ SQLs in 6 months.

Data enrichment tools FAQ
What are the top data enrichment companies?
The names most B2B buyers shortlist are ZoomInfo, HubSpot (which bought Clearbit and now sells it as Breeze Intelligence), Apollo.io, Cognism, 6sense and Demandbase, with People Data Labs supplying data to many other tools through its API. Clay and BetterContact are the fastest-growing names because they sit on top of those databases and query several at once. Ownership matters when you buy: a tool that resells another vendor's data inherits that vendor's gaps.
What is an example of data enrichment?
A record arrives from a webinar form as a name and a work email. Enrichment returns the job title, seniority, company headcount, industry, HQ country, tech stack and last funding round, then verifies the email and finds a mobile number. The rep now knows the person is a VP at a 300-person fintech that raised a Series B last quarter and runs HubSpot, which decides both whether to call and what to say.
What is a B2B data provider?
A B2B data provider owns or licenses a database of companies and business contacts and sells access to it, by seat, by credit or by API call. An enrichment tool uses one or more of those databases to fill in records you already hold. Many vendors are both. Reachly compares the database side, priced per email, in the best B2B data providers.
Who are the top B2B data providers?
ZoomInfo, Apollo.io, Cognism, Lusha and People Data Labs hold the largest contact databases, and AI Ark, Icypeas, Prospeo and LeadMagic are cheaper per verified email. The cheapest by list price is not always cheapest per usable record, because match rates differ by region and segment, so test each one on your own ICP before committing to an annual plan.
What is a B2B database?
A B2B database is a structured set of company and contact records, typically company name, domain, industry, headcount, location, contact name, title, email and phone, kept current by crawling, licensing and verification. Its value depends on how recently each record was checked: a database refreshed quarterly can still carry a contact who changed jobs last month, which is why outbound teams re-verify before every send.
