The Best AI Data Enrichment Tools for Small B2B Teams of 2026

We read the current pricing pages, credit rules, and official docs for the five enrichment platforms small B2B teams actually shortlist, and scored each on how well it turns a raw list into contacts your reps can reach.

The Verdict

For most small B2B teams, Apollo.io is the safe default. One paid seat gets you a searchable contact database, unlimited email addresses on paying plans, and a credit pool for phone reveals, all on a self-serve plan you can start Monday morning. If your workflow is already spreadsheet-and-waterfall and you want to combine multiple data vendors on one bill, Clay's new Launch plan at $185/month is the enrichment cockpit to buy. And if you're a founder or two-person team who just needs verified work emails without a subscription argument, LeadMagic's pay-per-result API and Hunter's flat credit tiers are both cheaper than either of the above.

Every small B2B team eventually hits the same wall. Your CRM is full of half-complete records, your outbound list is 40% bounces, and the SDR spends half her day on LinkedIn instead of in a sequence. AI-powered enrichment tools are the layer that fixes that. They take a domain, a LinkedIn URL, or a first-last-and-company and hand back a verified work email, a mobile number, a job title, and enough firmographic detail to personalize an outreach.

We looked at the five enrichment platforms small B2B teams shortlist most often in 2026, read each vendor's current pricing and documentation pages end to end, priced the same illustrative workload against every published rate card, and graded each on the things that decide whether the tool earns its keep on a small team's budget. No customer quotes, no laboratory bench. This is a documentation and pricing comparison, and we say so plainly in every metric below.

How We Tested

Every score below reflects current official pricing pages, product documentation, and each vendor's stated capability set as of early September 2026. Where we cite a number, it comes from that vendor's own page and appears in the Sources list. We weighted small-team affordability, credit efficiency, and data breadth most heavily, because those are what actually govern whether a five-person sales team can run this tool without a monthly finance conversation.

Small-Team Affordability

We read each vendor's official pricing page and priced the realistic entry cost for a two-to-five-person sales team enriching roughly 1,000 contacts a month with a work email and a mobile number, factoring in published seat rules, credit allocations, contract requirements, and any required host platform (for example, Breeze Intelligence requiring a paid HubSpot subscription).

Credit & Pricing Transparency

We compared what each vendor publishes on its own pricing page against what a buyer actually has to do to get to a number: whether tier prices, credit allocations, roll-over rules, overage rates, and enterprise thresholds are stated in the open or require a demo, and we penalized quote-only models where a small team cannot see a price without a sales conversation.

Data Breadth

We compared each vendor's documented data coverage: number of contacts in the database, number of connected data providers, whether phone or mobile enrichment is included at the entry tier, and whether the tool supports firmographic and technographic fields beyond email, using only the counts each vendor publishes on its own site.

Small-Team Workflow Fit

We evaluated whether each tool ships with the pieces a small team actually needs alongside enrichment (search, sequencing, CRM sync, a Chrome extension, a usable free plan) versus the pieces the customer must bolt on themselves, based on each vendor's own feature and plan documentation.

Speed to First Value

We read each vendor's onboarding docs and pricing page to judge how quickly a small team could go from signup to a first enriched record without a demo, an annual contract, or a mandatory host-platform subscription. The closer to self-serve, the higher the score.

Contract Flexibility

We compared each vendor's published contract terms: whether monthly billing is offered, whether annual commitment is required, what happens at renewal, and whether seats or credits can be reduced mid-term, penalizing forced annual lock-ins and rewarding cancel-anytime self-serve billing.

Apollo.io
by Apollo
Editor's Choice
8.9/10

The safe default for most small B2B teams. One self-serve seat gets you a 230M+ contact database, unlimited email reveals on paid plans, and a credit pool sized for real outbound, with published per-seat prices you can start on today.

Best for: Most small B2B sales teams

Why We Like It

  • Free plan is genuinely useful for evaluating data quality before paying
  • Published, self-serve per-seat pricing at $49, $79, and $119/user/month annual
  • Combines database, sequencing, dialer, and CRM sync so a small team doesn't need a second tool

Watch Out For

  • The Organization plan has a three-user minimum, which forces small teams to skip it
  • Credit consumption scales with reveals and exports, and G2 reviewers frequently report credits feeling restrictive at lower tiers

Clay
by Clay
Best Value
8.6/10

The enrichment cockpit. Launch at $185/month gives a technical small team a spreadsheet-native workspace that pulls 150+ data providers into a single waterfall, with per-credit costs designed to scale down as usage grows.

Best for: Technical GTM teams building custom enrichment workflows

Why We Like It

  • Access to 150+ data partners through one interface with waterfall enrichment
  • Free plan (100 Data Credits, 500 Actions/mo) is enough to prove the workflow before paying
  • Unlimited seats on every plan; pricing scales by usage, not headcount

Watch Out For

  • Steep learning curve. Clay's own docs recommend a technical operator for advanced workflows
  • On plans where you bring third-party API keys, Actions still meter even when the underlying enrichment doesn't return the field you wanted

Hunter.io
by Hunter
Best for Beginners
8.4/10

The best pick if you already know which companies to target and just need clean, verified work emails. Transparent published pricing, no per-seat fees, and a Free plan that's actually usable for evaluation.

Best for: Founders and small teams doing domain-first prospecting

Why We Like It

  • Genuinely useful Free plan: 50 credits/month, one connected mailbox, and 500 campaign recipients
  • No per-seat fees. A five-person team pays the plan price, not five times the plan price
  • Published Starter/Growth/Scale tiers ($34/$104/$209 on annual billing) make budgeting easy

Watch Out For

  • Email-only: no phone or mobile enrichment, so you pair it with another tool for calling
  • A single monthly credit pool covers Domain Search, Email Finder, and Email Verifier, so every clean contact burns from that shared allowance

LeadMagic

Technical founders and GTM engineers
8.0/10

The API-first enrichment layer. Pay-per-result pricing, an unmetered search API on higher tiers, and MCP support for Claude and Cursor. The right pick for a technical founder who wants to own the data layer.

Best for: Technical founders and GTM engineers

Why We Like It

  • Credits are only deducted on successful results, so failed lookups don't burn budget
  • Every plan includes the full API, lm-tui, MCP server, and all 15+ enrichment endpoints on one shared credit pool
  • Predictable published tiers from $49.99/mo for 2,000 credits to $849/mo for 100,000 credits, with unused credits rolling over on Essential and above and no annual contract required

Watch Out For

  • No polished UI for non-technical users. This is a data API, not a full sales platform
  • No native sequencer or CRM UI; you bring your own outreach and CRM tools

HubSpot Breeze Intelligence (formerly Clearbit)
by HubSpot
Small teams already committed to HubSpot
7.1/10

The right pick if, and only if, you're already on a paid HubSpot subscription. Enrichment runs automatically on CRM records, but the tool isn't sold as a standalone product anymore.

Best for: Small teams already committed to HubSpot

Why We Like It

  • Data enrichment doesn't consume HubSpot Credits on paid plans, so basic enrichment is included with your subscription
  • Native to HubSpot: enrichment runs on record creation, no separate vendor to manage
  • Bundled buyer intent and form shortening on qualifying tiers

Watch Out For

  • Requires a paid HubSpot subscription. There's no standalone access anymore
  • No phone number enrichment
  • Additional Breeze Intelligence credits expire monthly with no rollover

What we were actually measuring

The point of an enrichment tool isn’t a bigger database. It’s fewer bounces, more dials that connect, and a shorter path from a spreadsheet of company names to a sequence that reaches a real buyer. That’s the job we scored against, and it’s why the rankings don’t track raw contact counts.

Two things shape the standings this year. First, Clay’s current self-serve pricing collapses its lineup into two published tiers (Launch and Growth) with a new credit system that scales Data Credit costs down as usage grows, moving Clay’s real per-record cost sharply down and making it a serious candidate for small teams. Second, all free Clearbit tools were shut down on April 30, 2024, and, as of 2026, the underlying data engine only ships as an add-on to a paid HubSpot subscription. That’s the reason Breeze Intelligence sits at the bottom of this list even though the underlying data is still strong: for a team that isn’t on HubSpot, the platform tax is enormous.

Why Apollo takes the top spot

Apollo wins the small-team default for one boring, decisive reason: everything a five-person sales team needs is on a self-serve, per-seat plan that publishes its own prices. Apollo offers four plans: Free ($0), Basic ($49/user/month annual), Professional ($79/user/month annual), and Organization ($119/user/month annual, minimum three users). Monthly billing adds roughly 20% to every paid tier, pushing prices to $59, $99, and $149 per user, and phone numbers cost 8 credits each while verified emails cost 1 credit each. There’s no demo required, no annual lock-in on the Basic and Professional tiers, and the free plan is genuinely usable for evaluating data quality.

The catch is credit consumption. Apollo’s hybrid model (fixed seat fee plus usage-based credits) sounds flexible, but in practice it often leads to budget volatility. Credits get burned every time your team reveals a contact, accesses a mobile number, or exports data. Credits don’t roll over. If you don’t use them, they disappear, and overages are charged automatically. For teams doing heavy phone outbound, that math can push the effective per-seat cost meaningfully above the sticker. It’s still the safest starting point, but budget carefully.

When Clay is worth the learning curve

Clay isn’t a replacement for Apollo. It’s a completely different tool that many small teams end up running alongside one. Instead of shipping a database, Clay ships a spreadsheet-native workspace and lets you plug more than a hundred data providers into a waterfall inside a single table. Launch, starting at $185/mo, is the best way to start building in Clay, aimed at individuals and small teams automating their first prospecting workflows. It includes everything in Free, plus phone number enrichment, job change and signal tracking, email campaign integrations, and up to 50,000 rows per table, and comes with 2,500 Data Credits and 15,000 Actions per month.

Clay’s current credit system is meaningfully cheaper per record than a lot of standalone providers. Data Credits start at $0.05 each and get more cost-effective as you scale. Clay prices data as competitively as it can by negotiating volume discounts directly with 150+ partners and passing those savings on, so the most-used enrichments cost 50% fewer credits on average. Clay’s own docs confirm one important detail for budgeting: if an enrichment returns no result, you’re not charged Data Credits or Actions. And unused Data Credits on Launch and Growth roll over up to 2x your monthly allocation, which softens the impact of a slow month.

Clay does have a real learning curve, and the platform is built around technical operators who can compose multi-step tables and waterfalls. If your team doesn’t have someone comfortable in that shape of tool, Apollo will get you to first meeting booked faster.

The cheap picks: Hunter and LeadMagic

If you already know which domains you want to reach and just need verified work emails on a real budget, Hunter and LeadMagic are both several times cheaper than either of the above.

Hunter is the most transparent tool in the category. Paid plans start at $34/mo on annual billing: Starter $49/mo ($34 annual), Growth $149 ($104), Scale $299 ($209), checked July 2026 on hunter.io/pricing. All are credit-based with connected-account caps of 3/10/20, and domain searches, email lookups, and verifications all draw from one monthly pool. Team access uses a shared credit pool across connected team members with no per-user fee, and that matters: a five-person team on the Growth plan pays $149/month total, compared to $245-395/month for the same team on Apollo. The reason Hunter isn’t higher on the list is scope. It finds and verifies emails, and that’s it. No phone numbers, no database you can mine by persona.

LeadMagic is the option we’d hand to a technical founder who wants to own the enrichment layer as an API rather than a UI. Every plan includes the full API, lm-tui, MCP server, and all 15+ enrichment endpoints with one shared credit pool. People, Company & Jobs Search is included from Essential up. Searching spends no credits, and $499+ plans add an unmetered search API. Pricing is straightforward: LeadMagic uses a credit-based model where 1 credit equals 1 enrichment, and you only pay for valid results. Paid plans run from $49.99/month for 2,000 credits (Basic) up to $99/month for 5,000 credits (Essential), $249/month for 20,000 (Growth), $499/month for 50,000 (Professional), and $849/month for 100,000 credits (Ultimate). Unused credits roll over on Essential and above (up to 2x monthly allocation), and no plan requires an annual contract. That combination (pay-for-success, roll-over credits, MCP support) is why it earns a rank ahead of Breeze on our scorecard, even though it lacks a polished UI.

For the step before enrichment, actually finding the accounts worth enriching in the first place, our sibling guide to the best AI lead generation tools for small B2B businesses of 2026 covers the tools that sit upstream of everything on this list.

Why Breeze Intelligence lands last

Clearbit was a category-defining product, and the underlying data engine still is. But the acquisition changed the buyer math completely. As of 2026, Clearbit (now sold as HubSpot Breeze Intelligence) starts at around $45/month for 100 enrichment credits, but that credit fee sits on top of a required paid HubSpot subscription (from $20/month), so the realistic all-in minimum is roughly $65/month. That entry number is misleading in the other direction, too. Teams needing additional HubSpot Credits for AI agent features and expanded buyer intent can buy them at $10 per 1,000 credits, and once you climb to HubSpot Professional the platform fee alone dwarfs anything else on this list.

There’s one important 2025 change that matters for HubSpot customers. On paid HubSpot plans, data enrichment and monthly continuous enrichment updates don’t consume HubSpot Credits. So if you’re already a paying HubSpot customer, basic enrichment is effectively free and Breeze becomes an easy yes. If you’re not a HubSpot customer, everything else on this list is a better buy.

One more small-team constraint to know: old Clearbit Prospector offered phones; Breeze dropped phone reveals entirely. If your team dials, Breeze is the wrong shape regardless of the HubSpot question.

The short version

Buy Apollo if you want one tool that a five-person team can run end to end. Buy Clay if you have a technical operator and want to combine data providers into custom waterfalls. Buy Hunter if you only need verified emails and want a shared credit pool with no per-seat math. Buy LeadMagic if you’d rather build the workflow yourself against a clean API. And buy Breeze only if you’re already deep inside HubSpot, in which case you’re mostly getting it for free anyway.

Frequently Asked Questions

What's the best AI data enrichment tool for a small B2B team in 2026?

For most small B2B teams, Apollo.io is the safe default. It publishes per-seat pricing at $49, $79, and $119 per user per month on annual billing, includes a free plan with 900 credits per year, and combines a searchable contact database, sequencing, dialer, and CRM sync in one self-serve platform. Clay is the better pick if you want a spreadsheet-native workspace that combines many data providers into one waterfall, and Hunter is the cheaper pick if you only need verified work emails.

How much does Clay cost on its current self-serve plans?

Clay's self-serve plans are Launch at $185/month (2,500 Data Credits and 15,000 Actions) and Growth at $495/month (6,000 Data Credits and 40,000 Actions), with roughly a 10% discount on annual billing. Enterprise is quote-only and requires an annual commitment. Data Credits start at $0.05 each and get cheaper as you scale, and unused Data Credits on Launch and Growth can bank up to 2x your monthly allocation.

Is Clearbit still available as a standalone product?

No. HubSpot acquired Clearbit in late 2023 and rebranded it as Breeze Intelligence, and the standalone Clearbit product is no longer sold. In 2026, using the underlying data engine requires a paid HubSpot subscription, and on paid HubSpot plans basic data enrichment doesn't consume HubSpot Credits.

Which enrichment tool has the best free plan for evaluation?

Three tools have a genuinely useful free tier for evaluation. Apollo offers a free plan with 900 credits per year and access to its full contact database with basic filters. Hunter offers 50 credits per month and one connected mailbox, which is enough to test data quality on your target market. Clay's Free tier gives 100 Data Credits and 500 Actions per month with unlimited seats and tables, which is enough to prove out a small workflow before paying.

Do I need a phone number in my enrichment tool?

Only if your outbound motion actually involves dialing. If your team lives in email and LinkedIn, Hunter or LeadMagic are cheaper and simpler because you skip the mobile-number premium. If cold calling is core to your process, Apollo bundles email and phone reveals into one credit pool on every paid plan, which is usually the cheapest way for a small team to add dial data without a separate vendor.
