Startup database and AI sourcing agent for venture investors
Harmonic is a startup-intelligence platform built mainly for venture investors. It says it tracks more than 35 million companies and 195 million people, from founders who have just incorporated to scale-ups hiring a CFO to go public, and refreshes records continuously rather than quarterly. It also maps a firm's own network onto that data (LinkedIn connections, email, calendar and CRM activity) to show warm introduction paths. Scout, its AI agent, answers research questions from that data: sourcing, market maps, valuation comps, thesis building and meeting prep. Data also ships through an API and bulk delivery to a customer's warehouse. Early customers included Floodgate, a16z and Accel, and startups such as Brex, Notion and Carta; the company says its investors were customers first. It publishes a quarterly 'Hot 25' list of in-demand early-stage startups. It started as a remote team and is now headquartered in New York.
