Company Overview
About Fiber AI
Fiber AI is a San Francisco-based AI B2B prospecting and data platform — backed by Y Combinator (S23) with seed funding from TRAC, Y Combinator, and Soma Capital — providing GTM teams, sales organizations, and recruiting teams at enterprises and fast-growing startups with a comprehensive contact data and prospect list building platform that aggregates 40+ million companies, 850+ million professionals, 13+ million jobs, and 50+ data providers to deliver verified contact information at 4x lower cost than alternatives like Clay, Apollo, or ZoomInfo. Founded in 2023 by Adi Agashe and Neel Mehta, Fiber AI serves customers including Ramp, DocuSign, and Flatfile — enabling surgical TAM (total addressable market) list building with advanced filters for targeted outbound prospecting and outbound recruiting.
Business Model & Competitive Advantage
Fiber AI's prospect data aggregation platform addresses the cost and accuracy problems with current B2B contact data: companies building prospect lists for outbound sales or recruiting pay $500-$3,000+ monthly for ZoomInfo or Apollo subscriptions to access business contact data that is often outdated (15-20% of business contacts turn over annually), missing coverage in non-US markets, and not enriched with the firmographic signal data (technology stack, hiring patterns, funding events) that makes outbound outreach relevant rather than generic. Fiber AI's multi-source aggregation (pulling from 50+ data providers and validating contact information against multiple sources for higher accuracy) provides the clean, comprehensive prospect data that enables outbound teams to run high-volume outreach campaigns without the email bounce rates and deliverability penalties that inaccurate contact data creates.
Competitive Landscape 2025–2026
In 2025, Fiber AI competes in the B2B sales intelligence, contact data, and prospecting platform market with ZoomInfo (NASDAQ: ZI, dominant B2B sales intelligence, $1B revenue), Apollo.io (sales intelligence and engagement, $100M raised at $1.6B valuation), and Clay (AI prospecting enrichment, $62M raised) for enterprise and growth-stage company sales and recruiting team B2B contact data and TAM list building platform adoption. Y Combinator S23 backing connects Fiber AI with the sales technology and go-to-market tools investment community. The Ramp and DocuSign enterprise customer references validate data quality for sophisticated GTM teams. The 2025 strategy focuses on growing the outbound recruiting use case (where LinkedIn Recruiter costs $10,000+/year), building the AI-powered signal enrichment for buyer intent and job change detection, and expanding the international data coverage for global GTM teams targeting EMEA and APAC prospects.
