Happenstance is an AI-powered people search and relationship intelligence platform that helps users discover relevant people through the networks they already have. Users connect accounts such as Gmail, LinkedIn, Google Calendar, Outlook, Twitter, and Instagram, allowing Happenstance to build a searchable map of their relationships. They can then describe the person they are looking for in natural language and receive ranked results along with warm paths showing who can introduce them. The platform is designed for sales, recruiting, fundraising, investing, hiring, and networking. It also supports groups, an API, MCP, CLI, and integrations with AI assistants such as ChatGPT and Claude. Happenstance says it has more than 500,000 users and does not use connected data to train AI models.
