Find Verified Emails & Phone Numbers for Outreach
Prospeo is a B2B contact-data API and app for finding and verifying professional emails and mobile numbers, plus searching a database of 200M+ contacts and 30M+ companies, aimed at outreach, sales, and marketing teams that need reliable enrichment data.
Prospeo is primarily a data-enrichment API rather than a full outbound platform. Its documented surface centers on person and company enrichment, search endpoints, account-usage introspection, and a revamped API whose old endpoints were scheduled for migration before March 1, 2026. It also exposes a hosted MCP server and an installable local MCP server package. A companion web app and Chrome extension were not verified in the retained official material.
Sales, marketing, and outreach teams that need a dedicated email/phone enrichment and verification data source to feed into their own sequencing, CRM, or no-code tooling, rather than an all-in-one outbound platform.
The Free plan explicitly excludes API access, so any team wanting programmatic or MCP access must move to a paid tier. Credits do not roll over month to month, which penalizes teams with uneven, bursty enrichment needs rather than steady volume. Teams wanting an all-in-one outbound platform (sequencing, multichannel campaigns, CRM sync built in) should look elsewhere - Prospeo's documented surface is enrichment/search data, not campaign execution.
Providers that resolve a person or company to verified contact data — email, phone, firmographics — through an API or a bulk upload.

We could not locate a machine-readable OpenAPI spec for it.
Yes, per Prospeo's own help center: 100 credits/month, 25 max row selection, 3 intent topics, basic filters only, limited CSV enrichment, and explicitly no API access.
The vendor's own help center lists four tiers (Free, Starter, Growth, Pro) with per-user monthly/yearly billing and credit allotments (Free: 100, Starter: 2,000, Growth: 5,000, Pro: 15,000 credits/user/month), but we did not verify the dollar amounts from the vendor's pricing page itself, so we are not recording third-party figures here.
No. Per Prospeo's own materials referenced in search results, credits expire monthly with no carry-over, and additional credits can be purchased as add-ons on paid plans.
200M+ contacts with 30+ filters via Search Person, and 30M+ companies via Search Company, per the vendor's own API docs summary.
Per third-party sources we did not independently verify against a vendor page, mobile numbers reportedly cost more credits than email addresses; we were not able to confirm the exact ratio on Prospeo's own site, so treat this as unverified.
This page tells you whether Prospeo fits. Cheetah builds and runs the system it goes into — enrichment, sequencing, CRM and the joins between them.
