What it is

Happenstance is a people-search service for finding people in your existing network and paths to introductions. It draws relationship signals from email headers, meetings, connections, follows, and contacts, then ranks people by how well you know them. Search results name matches, explain why they surfaced, and show a direct, friend, or group route. It connects to Gmail, Outlook, Google Calendar, Google Contacts, LinkedIn, Twitter, and Instagram. Friends can share networks mutually; groups pool member networks for teams, funds, cohorts, or communities, and groups are free and unlimited. For agents and applications, Happenstance offers a REST API, MCP server, OpenAPI specification, and CLI, and it works with ChatGPT, Claude, Claude Code, and OpenClaw. Its iPhone app includes natural-language search, ranked warm paths, saved lists, introduction drafting, and network updates. Email and direct-message content and attachments are not sent to its servers; it uses sender, recipient, and timing metadata. The Free plan has Chat usage limits. Team is $24 a month per seat; Pro is $30 a month.
