About the Company
Our client is building a real-time people-data platform that provides deep context on individuals to power intelligent agents and next-generation applications.
The platform dispatches tens of millions of autonomous AI agents across the open web to collect unique signals including GitHub activity, social posts, professional updates, company changes, career movements, and other difficult-to-capture behavioral data.
These signals are connected at the individual level, creating a structured knowledge graph that spans hundreds of millions of websites and enables applications to reason about people using rich, real-time context.
The platform is used by recruiting teams to identify and qualify talent with greater precision and by growth teams to uncover buyer intent and identify high-value prospects.
The company is an extremely early-stage, founder-led organization with a small technical team and approximately $5.5M in funding. Engineers work directly with the CEO and CTO and have significant ownership over foundational infrastructure and technical strategy.
