6 Best Phone Number Finder Tools for Startups (2026)

A phone number finder returns a direct dial or mobile number for a B2B contact from a name, a LinkedIn URL or an email. A startup needs one when the first ten customers will not answer email and a founder has to call.

Startups buy on three things: a price they can start small on, no seat tax, and an API so the lookup runs inside the product or an agent. Most tools charge 5 to 10 credits for a mobile, so a cheap plan buys only a few hundred phones. We compared the published pricing, API and MCP docs of six tools in September 2026. We did not run a hit-rate test, so no find rate below is ours. For the wider field, see the full phone finder list. To compare one vendor head to head, read Apollo, Prospeo, FullEnrich, LeadMagic or Lusha against LeadOcean.

TL;DR

What we evaluated

• Cost of one phone. The credits or dollars a mobile number costs, and whether a miss is charged.
• Entry price. What a founder pays in month one, and whether a free plan exists.
• API access. Whether a key is on the cheap plans and how fast it runs.
• Seats. Whether the price grows with every person who needs the data.
• Volume. What 1M records a month would cost, using only published prices.

1. LeadOcean: best for technical founders who pull phones in code or with an agent

LeadOcean is a data API with a hosted MCP server. It holds 693M people, and 166M of them have a phone number. You call GET /v2/people/phone, or the find_phone tool over MCP, and you get the number back (LeadOcean pricing, October 2026).

The price is a flat monthly fee with no credits and no seats. Free gives 1,000 records for life with no card, so a founder can run up to 1,000 phone lookups before paying anything. Solo is $97 a month for one person at 50 requests a second. Agency is $497 a month at 200 requests a second, with 5 keys.

LeadOcean is not a rep tool. There is no dialer, sequencer, CRM or Chrome extension. The app at app.leadocean.io has an Exports page with a filter builder, a column picker, a price preview and a CSV download. If your first hire is a salesperson who wants a screen to work in, rank Apollo above it.

Pros

• Phones are included on Solo and Agency, with no per-phone credit.
• 13 MCP tools, including find_phone, over OAuth with no key pasted.
• No seat price. A new hire shares the plan, not a new bill.
• A free count call sizes a list before you spend a record.

Cons

• A v2 contact call that finds nothing still costs one record.
• No browser extension, dialer or CRM for reps.
• Bulk CSV export is not on Free.

Best for: founders and engineers who call phones from code, a product or an agent.

Pricing: Free $0, Solo $97, Agency $497, Platform $1,997 a month (LeadOcean pricing, October 2026).

2. Apollo: best for founders who want a rep workspace and a free plan

Apollo is the default startup choice because it bundles a database, sequences and a free plan. Free is $0 with 75 credits a month. Basic is $65 per seat a month with 2,500 credits, or $49 billed yearly (Apollo pricing, September 2026).

A phone costs 8 credits and an email 1. Free therefore buys about 9 mobiles a month, and Basic about 312. Credits are pooled across the team, expire at the end of each billing cycle and do not roll over (Apollo API pricing, September 2026).

Every plan includes API access. Paid plans allow 1,000 enrichment requests a minute, and Free allows 50 a minute and 600 a day (Apollo rate limits, September 2026). The official MCP server works on any plan, Free included, and spends the same credits (Apollo MCP docs, September 2026).

Pros

• A free plan with API and MCP access.
• Sequences, a database and enrichment in one seat.
• Enrichment runs up to 1,000 requests a minute on paid plans.

Cons

• 8 credits per phone makes the entry plans small for phone work.
• Pricing is per seat, and Organization needs a minimum of 3 seats.
• Credits expire each cycle.

Best for: non-technical founders who want one tool for data and outreach.

Pricing: Free $0, Basic $65, Professional $99, Organization $149 per seat a month. Billed yearly: $49, $79 and $119 (Apollo pricing, September 2026).

3. Prospeo: best for small teams on cheap per-seat plans

Prospeo sells per-user plans with a shared credit pool. A mobile costs 10 credits and a verified email 1. A lookup with no result costs 0, and re-enriching the same record within 90 days costs 0 (Prospeo credits, September 2026).

Free is $0 with 100 credits a month, which is 10 mobiles. Starter is $49 per user a month for 2,000 credits, or 200 mobiles. Billed yearly, Starter is $37 a month for 24,000 credits a year (Prospeo pricing, September 2026).

The enrich API runs at 5 requests a second on Starter and Growth and 30 on Pro. The hosted MCP server has 8 tools and takes OAuth or an API key (Prospeo rate limits, September 2026; Prospeo MCP docs, September 2026).

Pros

• Misses and repeat lookups inside 90 days cost nothing.
• An 8-tool hosted MCP server with OAuth.
• A low entry price for one user.

Cons

• 10 credits per mobile limits Starter to 200 phones a month.
• Credits expire at the end of each cycle.
• No single tier reaches 1M credits a month.

Best for: a two-to-five person team that wants cheap seats and no charge for misses.

Pricing: Starter $49, Growth $99, Pro $249 per user a month. Billed yearly: $37, $74 and $187 (Prospeo pricing, September 2026).

4. FullEnrich: best for founders who want a free miss and many sources

FullEnrich runs one lookup across 25+ data sources and returns the first match it can verify. A mobile costs 10 credits, a work email 1 and a personal email 3. A lookup that finds nothing, or returns a landline, costs 0 (FullEnrich credit docs, September 2026).

Pro starts at $29 a month for 500 credits, which is 50 mobiles. Billed yearly, the entry tier is $26 a month. The free trial gives 50 credits with no card. API, MCP, search and bulk CSV are on every plan, and users are unlimited (FullEnrich pricing, September 2026).

The API allows 60 calls a minute, with up to 100 contacts per bulk request (FullEnrich volume docs, September 2026). Monthly tiers stop at 100,000 credits for $3,500, then it is sales.

Pros

• No charge when a lookup finds nothing.
• Unlimited users on every plan, so seats cost nothing.
• API and MCP on every plan, including the trial.

Cons

• 500 credits buys only 50 mobiles on the entry plan.
• 60 calls a minute is slow without bulk requests.
• The trial is 50 credits, which is 5 mobiles.

Best for: founders who want to pay only for a match and do not want per-seat pricing.

Pricing: Pro from $29 a month for 500 credits ($26 billed yearly). Free trial is 50 credits (FullEnrich pricing, September 2026).

5. LeadMagic: best for pay-as-you-go credits with a hosted MCP server

LeadMagic has the lowest dollar price per mobile among the credit tools here. Mobile Finder costs 5 credits, and Essential is $99 a month for 5,000 credits, which is about 1,000 mobiles, or about $0.10 each (LeadMagic pricing, September 2026). An email finder call costs 1 credit and a miss is free (LeadMagic credit guide, September 2026).

There is no free plan and no trial credits. It is a $99 a month start with a 14-day money-back guarantee on the first payment (LeadMagic plans FAQ, September 2026). Seats are 3 on Essential and 5 on Growth, all sharing one credit pool.

LeadMagic runs a hosted MCP server with OAuth-only sign-in, so static API keys are not accepted over MCP (LeadMagic MCP, October 2026). Credits roll over on monthly plans, up to 2x the monthly allocation.

Pros

• 5 credits per mobile, tied with Lusha for the fewest credits per phone here.
• Credits roll over on monthly plans.
• Seats are bundled: 3 on Essential, 5 on Growth.

Cons

• No free plan, so the first test costs $99.
• MCP sign-in is OAuth only.
• No public price at 1M a month.

Best for: a funded startup that has a phone list to fill and wants pay-as-you-go credits.

Pricing: Essential $99, Growth $249, Professional $499, Ultimate $849 a month; billed yearly $83, $208, $416 and $708 a month (LeadMagic pricing, September 2026).

6. Lusha: best for reps who work in the browser

Lusha puts a browser extension in front of its credits. A phone costs 5 credits and an email 1. Email plus phone is 7 credits through a single API request (Lusha API guide, September 2026).

Free is 40 credits a month, about 8 phones. Starter is $49.90 a month for 400 credits, about 80 phones, billed yearly at $37.45 (Lusha pricing, September 2026). Starter includes one seat, and Pro adds a second.

Every plan has an API key. Free and Starter allow 40 requests a minute and 100 a day. The MCP server has 50 tools and shares the REST credit pool (Lusha MCP tools, September 2026).

Pros

• A browser extension and an API on one credit pool.
• A 50-tool MCP server.
• A Free plan with an API key.

Cons

• The daily cap of 100 API requests on Free and Starter blocks batch work.

Best for: a founder or first sales hire who looks up a few contacts a day in the browser.

Pricing: Starter $49.90 a month ($37.45 billed yearly), Pro $69.90 ($52.45), Premium $399.90 ($299.95) (Lusha pricing, September 2026).
