About Fiber AI

Fiber AI provides data APIs specifically designed for AI sales and recruiting agents, offering access to a continuously updated database of over 40 million companies, 850 million professionals, and 35 million jobs. The platform features exclusive endpoints not found in other data providers, including reverse email lookup (work and personal), partial/incomplete search for people and companies, granular filters beyond LinkedIn Sales Navigator, real-time LinkedIn company and profile data, and email bounce detection/verification. Used by companies like Hubspot, Agent AI, and Rogo AI, Fiber AI enables enrichment of CRM data, building of targeted prospect lists, and seamless integration via RESTful APIs with JSON responses. The team is founded by Adi Agashe and Neel Mehta (both Forbes 30 Under 30 2024) and backed by notable investors including Dharmesh Shah (co-founder of HubSpot).
