Happenstance

Happenstance connects to your Gmail, Outlook, LinkedIn, Twitter, Instagram, and Google Calendar accounts to build a unified graph of your professional relationships. You can search this graph using natural language queries like “fintech VP of Engineering in NYC” or “Stanford alum founder pre-seed” and the AI returns ranked matches with confidence scores and mutual connection paths.

The tool also supports team use through Groups, where everyone in a company or community pools their networks into one searchable database. This is useful for recruiting teams, sales organizations, and VC firms that want to find warm paths to candidates or prospects across their collective contacts. Domain auto-join, shared credits, and team-wide search are available for group accounts.

Happenstance offers an API for programmatic access, so you can run batch searches against lists of target companies, trigger searches from meeting transcripts, or build custom workflows. The tool is a Y Combinator W24 company backed by Garry Tan and Elad Gil, and reports 400,000+ users. A free plan is available with basic search, and the Pro plan at $24 per month adds unlimited searches, CSV export, Slack integration, and early feature access.
