Happenstance

Happenstance is people search over your own network. You connect the accounts where your relationships already live, including Gmail, Outlook, Google Calendar, Google Contacts, LinkedIn, Twitter and Instagram, and then ask in plain English who you know and who can introduce you. It builds one map of everyone you know, scores each relationship by how well you know the person, and returns every result with a warm path in. It is built for sales, recruiting, fundraising and job searching, where the right introduction matters more than a cold message. Beyond your own accounts, you can add friends and join groups to search your networks' networks, and Happenstance Chat can draft an intro request to your strongest mutual connection. Email is read as headers only, which is enough to judge how well two people know each other. The product also works inside ChatGPT and Claude through an MCP server, and developers can call it through an API or a command line tool. The vendor states it is SOC 2 compliant and that user data is never used to train AI models. Pricing is published. Free costs $0 forever and includes Happenstance Chat with usage limits, unlimited connected accounts and unlimited friends and groups, with no credit card required. Pro is $24 per month billed yearly, which the page labels as 20% off, and adds higher chat limits and export of people from chat to CSV. Team is $24 per seat per month and lets an organization assign Pro seats to specific members, buy API credits and track usage per member on a single invoice. API and MCP usage draw on separate credits.
