6 Best Lead Enrichment Tools for Small Businesses (2026)

Lead enrichment is the step that turns a name, domain or LinkedIn URL into a verified email, a phone number and company details you can act on. Small businesses need it without a sales contract, a seat for every rep or a credit meter that runs out on the 20th.

Most teams start with a rep-facing tool and outgrow it. Apollo bills per seat (Apollo pricing, September 2026). Hunter and Prospeo bill per credit (Hunter, September 2026; Prospeo, September 2026). Clay charges for Data Credits and Actions (Clay, September 2026). Each model is fine at 500 leads a month and expensive at 50,000. This page ranks six tools for a small buyer. LeadOcean is one of them; see the Hunter.io alternative and Clay alternative pages for the head-to-head.

TL;DR

Cost at 1M is the list price of 1,000,000 work-email lookups, as worked out in the Pricing lines below. Where a vendor publishes no price at that volume, we say so and do not multiply a rate out.

What we evaluated

• Free tier. Can you test it on real leads before paying, and does the free plan include the API?
• Price model. Credits, seats or a flat fee, and what each does to your bill when volume triples.
• API and MCP. A documented REST API, and an MCP server if an AI agent needs to call the tool.
• Seats. Whether a second teammate doubles the bill.
• Cost at 1M records a month. The published price of a large month, so you know the ceiling before you hit it.

1. Apollo: best for a small sales team that wants one app

Apollo is a database and outreach tool in one login. A small team can find contacts, enrich them and send sequences without a second subscription. The Free plan gives 75 credits a month and every plan includes API access (Apollo developer FAQ, September 2026).

The catch is the seat. Credits are granted per seat each month and expire at the end of the billing cycle. An email costs 1 credit and a phone number costs 8 (Apollo API pricing, September 2026). Basic gives 2,500 credits per seat on monthly billing. Add reps and the credits come with them. Add volume without reps and the price is not public: Apollo prints no rate for extra credits.

Apollo runs an official MCP server at mcp.apollo.io on every plan, Free included (Apollo MCP docs, September 2026). Enrichment through MCP spends the same credits.

Pros

• Data, sequences and a CRM view in one app.
• Free plan with API access and an MCP server.
• Paid plans allow 1,000 enrichment calls a minute with no hourly or daily cap (Apollo rate limits, September 2026).
• Yearly billing cuts the seat price by 24 percent.

Cons

• Credits are per seat and expire each cycle.
• A phone number costs 8 credits, so mobile-heavy lists drain a plan fast.
• No public price for extra credits.
• Search is capped at 50,000 calls a day on paid plans.

Best for: a team of 2 to 10 reps who also want to send sequences from the same tool. Pricing: Free $0 with 75 credits a month; Basic $65 per seat a month with 2,500 credits, $49 billed yearly. 1M lookups is 250 Professional seats at $99, or $24,750 a month, on monthly billing (Apollo pricing, September 2026).

2. Hunter: best for finding emails by domain

Hunter finds and verifies work emails from a domain or a name plus a domain. It is simple, cheap at small volume and has a free plan with 50 credits a month. One credit is one email found, and nothing is charged when nothing is found (Hunter help, September 2026).

Unlimited team members share one credit pool, so Hunter does not tax a second user. The all-in-one plans run $49 (Starter, 2,000 credits), $149 (Growth, 10,000) and $299 (Scale, 25,000) a month on monthly billing (Hunter pricing, September 2026). The pricing page opens on yearly figures, so check which toggle you are reading.

For larger pulls, the API-only Data Platform sells credits as one-off packs valid 12 months, down to $0.0069 a credit at 1,000,000 (Hunter Data Platform, September 2026). There is an official MCP server at mcp.hunter.io on all plans (Hunter MCP, September 2026).

Pros

• Free plan, and no seat charge for extra teammates.
• No credit used when nothing is found.
• Cheapest published 1M price in this list among credit tools.
• Official MCP server on every plan.

Cons

• The lookup starts at a domain. You cannot build a list by title or seniority.
• Built around emails and domains, not full contact profiles.
• Monthly credits do not carry over.
• A rate-limited call returns 403, and 429 means your quota is spent (Hunter API docs, September 2026).

Best for: a small business that already has the company list and needs the emails. Pricing: Free $0 with 50 credits; Starter $49 a month with 2,000 credits, $34 billed yearly. 1,000,000 Search credits cost $6,900, bought once (Hunter pricing, September 2026).

3. LeadOcean: best for founders and developers who pull data by API or agent

LeadOcean is a data API and a hosted MCP server over 693M people and 67M companies. There are no credits on paid plans. Solo is $97 a month for one person, Agency is $497 a month for a team, and both run on a fair-use pace (LeadOcean pricing, October 2026).

The Free plan is 1,000 records for life, with no card and every feature, including search and enrichment through the API. A small business can test the real data before it pays. Counts and filter lookups for sizing are free.

It is not a rep tool. There are no sequences, no dialer, no CRM and no Chrome extension. The account app has an Exports page with a filter builder, a column picker and a price preview before you download a CSV (LeadOcean exports docs, October 2026). Bulk CSV export is not on Free.

The MCP server has 13 tools and signs in with OAuth (LeadOcean MCP docs, October 2026). Point Claude or ChatGPT at it and ask for a list in plain language.

Pros

• Flat price. Volume does not change the bill.
• Search by title, industry, location and 50 people filters, not only by domain.
• Free plan includes the API and the MCP server.
• Free counts size a list before you spend a record.

Cons

• No outreach, dialer or CRM. You send from another tool.
• The Free plan is 1,000 records once, not 1,000 a month.
• Solo is for one person. A team needs Agency at $497.

Best for: a founder, developer or small agency that builds lists in code or through an agent. Pricing: Free $0; Solo $97 a month; Agency $497 a month, 200 requests a second (LeadOcean pricing, October 2026).

4. Prospeo: best for email and mobile finding at a clean credit price

Prospeo finds verified emails and mobile numbers, with a clear credit table. One credit is a verified email, 10 credits is a mobile number with the email included, and re-enriching the same record inside 90 days is free (Prospeo credits, September 2026).

Plans are per user: Free is $0 with 100 credits a month, Starter $49 with 2,000, Growth $99 with 5,000 and Pro $249 with 15,000 (Prospeo pricing, September 2026). Seat credits pool across the team, so a second user adds credits as well as cost. Unused credits expire at the end of the cycle.

The hosted MCP server has 8 tools and signs in with OAuth or an API key (Prospeo MCP docs, September 2026). The Enrich API allows 5 requests a second on Starter and Growth and 30 on Pro (Prospeo rate limits, September 2026).

Pros

• Per-credit price falls as you move up plans, to $0.0125 on Pro billed yearly.
• A re-enrich of the same record inside 90 days costs nothing.
• Mobile numbers are sold per lookup, with the email included.
• MCP server with OAuth.

Cons

• No single plan reaches 1M. The cheapest public route is 44 Pro seats plus an add-on.
• Credits expire each cycle.
• Free-plan API access is stated differently on the pricing page and in the help center.
• Mobile numbers cost 10 credits.

Best for: a small team that wants emails and some mobiles at a predictable per-credit price. Pricing: Free $0 with 100 credits; Starter $49 a month with 2,000 credits, $37 billed yearly (Prospeo pricing, September 2026).

5. Lusha: best for reps who work inside LinkedIn and a CRM

Lusha is a contact finder built around a browser extension and CRM integrations. The Free plan gives 40 credits a month with one seat and no card (Lusha pricing, September 2026).

An email costs 1 credit, a phone number 5 credits, and email plus phone through one API request costs 7 (Lusha API guide, September 2026). Pro runs from 600 credits at $69.90 a month, and Premium reaches 10,000 credits at $977.40 a month on monthly billing. Pro includes 2 seats and Premium 5.

Every plan gets an API key, and the MCP server has 50 tools that share the REST credit pool (Lusha MCP docs, September 2026). The top public tier tops out far below 1M a month, and Scale is custom.

Pros

• Free plan, and an API key on every plan.
• Strong fit for a rep who browses LinkedIn all day.
• MCP server with 50 tools.
• Seats come bundled with Pro and Premium.

Cons

• Small credit counts: 10,000 a month on the highest public tier.

• No public price at 1M a month.
• Rate limits are low on Free and Starter: 40 a minute and 100 a day.

Best for: a one-to-five person sales team that prospects from LinkedIn and logs to a CRM. Pricing: Free $0 with 40 credits; Pro from $69.90 a month for 600 credits, or $52.45 a month billed yearly ($629.10 a year) (Lusha pricing, September 2026).

6. Clay: best for operators who build enrichment workflows

Clay is a spreadsheet that chains enrichment providers. It is the most flexible tool here and the hardest to price. Clay's own docs say a fully enriched record typically costs 6 to 20 Data Credits plus one Action per enrichment (Clay docs, September 2026).

The Free plan is $0 with 100 Data Credits and 500 Actions a month, unlimited seats and no phone enrichment. Launch starts at $185 a month and Growth at $495 a month on monthly billing (Clay pricing, September 2026). Data Credits start at $0.05 each.

Clay's Public API is on every plan, Free included (Clay docs, September 2026). The HTTP API column, which calls an outside API from a table, is Growth and above. Clay also publishes an MCP guide (Clay MCP guide, September 2026).

Pros

• Waterfalls across many providers in one table.
• Unlimited seats on the Free plan.
• No charge when an enrichment returns nothing.
• Public API on every plan.

Cons

• Credit-plus-Action pricing is hard to forecast.
• A real enrichment costs 6 to 20 Data Credits.
• The largest self-serve tier is 200,000 Actions and 50,000 Data Credits a month.
• Learning curve, and no outreach tool built in.

Best for: an ops-minded founder who wants to build a repeatable enrichment workflow. Pricing: Free $0; Launch $185 a month, $167 billed yearly; Growth $495 a month, $446 billed yearly (Clay pricing, September 2026).

Comparison table

How to choose

• You want one app for data and outreach. Apollo. Accept the seat model.
• You already have the company list and need emails. Hunter. The Data Platform is the cheapest published route to 1M among the credit tools.
• You build lists in code or ask an agent for them. LeadOcean. The flat price removes the per-record math.
• You want mobiles and emails at a clear per-credit rate. Prospeo.
• You prospect from LinkedIn and sync to a CRM. Lusha.
• You want to chain providers into a workflow. Clay, with a budget for Data Credits and Actions.
• You have no budget yet. Start with the free plans. Hunter, Prospeo and Lusha give small monthly credits. LeadOcean gives 1,000 records once.

Verdict

For a small team that works in a sales app, Apollo wins: it is the only tool here that bundles data and sequences. For email lookups from a known domain list, Hunter wins on price. For founders, developers and agencies who pull data through an API or an MCP agent, LeadOcean wins. A flat $97 or $497 a month does not change when volume does. Prospeo is the pick for mobile numbers at a published rate, Lusha for LinkedIn-first reps, and Clay for people who want to build workflows.
