What FullEnrich does
FullEnrich is a B2B waterfall data enrichment platform that sequentially queries 20+ third-party contact data vendors (including Clearbit, Hunter, Wiza, Snov, ContactOut, Anymail Finder, and Crunchbase) to find verified work emails and phone numbers. The company claims 80%+ email find rates versus 40-60% for single-provider tools, supported by triple email verification that delivers sub-1% bounce rates, mobile-first phone enrichment with line-ownership validation, and catch-all email detection at 80% accuracy. Coverage extends across 80+ countries spanning US/Canada, EMEA, LATAM, and APAC, with localized vendor selection per region. The platform supports native Model Context Protocol (MCP) integration, enabling AI agents such as Claude and OpenAI to invoke enrichment programmatically.
The company operates a hybrid go-to-market motion combining a product-led growth self-serve channel (50-lead free trial, no credit card) with a sales-assisted enterprise tier. Pricing is credit-based: Starter at $29/month for 500 credits, Pro at $55/month for 1,000 credits, and custom-priced Scaleups plans with unlimited team seats. Distribution channels include a web application at app.fullenrich.com, a REST API for programmatic access, a live HubSpot CRM integration with Salesforce and Pipedrive listed as coming soon, and no-code automation partnerships with Zapier, Make, n8n, and Clay. The platform is SOC 2 Type II, GDPR, and CCPA compliant.
FullEnrich was founded in 2023 in Paris, France and later relocated its headquarters to San Francisco, California. The company bootstrapped to seven-figure annual recurring revenue with only five employees before raising its first institutional seed round of approximately $2 million (€1.9 million) in February 2025, led by Flex Capital with participation from M-Fund, Kima Ventures, First Degree, Offord Ventures, and Duro Ventures. Named enterprise customers include Mastercard, DocuSign, Brevo, and Deel, with additional references including 11x and Meero. Headcount is reported in the 11-50 range post-funding.

FullEnrich competitors and assessment
Company assessmentDirect peers
- Snov.io: Snov.io provides email finding, verification, and drip campaign automation for B2B sales. It is both a competitor in email enrichment and one of FullEnrich's underlying waterfall data vendors.
- Adapt.io: Adapt.io offers a B2B contact database and enrichment API with a credit-based model targeting sales and marketing teams. It overlaps with FullEnrich on enrichment-as-a-service and global contact coverage.
- Clearbit: Clearbit (now part of HubSpot) provides B2B data enrichment APIs and a contact database used by marketing and sales teams. It is both a direct competitor to FullEnrich and one of its underlying waterfall data vendors, illustrating the aggregator/competitor tension in the model.
- Cognism: Cognism is a B2B sales intelligence platform with a phone-first approach, premium EMEA coverage, and Diamond Data verification. It targets the same enterprise outbound use cases as FullEnrich and emphasizes data quality similar to FullEnrich's waterfall verification claims.
- Apollo.io: Apollo is a leading B2B sales intelligence and engagement platform combining a contact database with email/phone enrichment, sequencing, and AI-driven prospecting. It is the closest comparable to FullEnrich in self-serve PLG motion targeting outbound sales teams, and FullEnrich's own marketing benchmarks against Apollo (84% find rate claim).
- Kaspr: Kaspr is a European-origin B2B contact data platform with strong LinkedIn Chrome extension adoption for phone and email capture. It directly competes with FullEnrich in phone enrichment and is referenced in FullEnrich's own customer case studies (73 vs 22 mobile numbers found).
- Lusha: Lusha offers B2B contact data with a strong phone number focus, browser-extension-driven prospecting, and CRM integrations. It directly competes with FullEnrich in mobile phone enrichment and credit-based self-serve pricing for outbound sales.
- RocketReach: RocketReach is a B2B contact and company lookup platform serving sales, recruiting, and marketing professionals. It directly competes in email/phone find rates and self-serve credit-based pricing.
- Hunter.io: Hunter is a widely used email-finding and verification platform for B2B outreach. It is both a competitor in single-provider email finding and one of the data vendors FullEnrich aggregates in its waterfall, making the relationship dual-edged.
Broad incumbents
- ZoomInfo: ZoomInfo is the largest B2B contact data and sales intelligence platform with proprietary first-party data, enrichment APIs, and intent data. It competes with FullEnrich across enterprise accounts at much greater scale and operates a vertically integrated model rather than an aggregator approach.
