About

Happenstance is an AI-powered people search and relationship intelligence platform designed to help users find the right individuals within their existing networks by simply describing who they are looking for in natural language. It turns fragmented connections across platforms like email, LinkedIn, Twitter, and shared team networks into a unified, searchable system, allowing users to run deep searches such as “a fintech PM in NYC” and instantly surface the most relevant matches based on intent, relationship strength, and context. It uses large language models and embedding search to understand queries and rank results intelligently, eliminating the need for manual filtering or complex queries while delivering precise, structured outputs that show how each match is connected. It enables users to expand their reach by combining networks with trusted friends or teams, making it possible to discover warm introductions, hidden connections, and high-value opportunities.
