Extruct AI is a company research API that finds and researches businesses from a curated index of 10 million companies or from anywhere on the live web. Describe the kind of company you want in plain language, run a search, lookalike or Deep Search, and each answer comes back with its source. Deep Search checks candidates against your criteria, so a query for Florida HVAC contractors serving hospitals can return sourced matches with headcount, location and founding year.
It fits teams that build lists of companies for a living: venture and private equity analysts mapping a market, sales and growth teams sourcing outbound targets, and consultants running market studies. Developers building AI agents can call the API directly to give those agents company data with citations, while non-technical users work in the Studio interface. A customer quote from an innovation analyst at True Capital describes typing what they want, having the list built and researched, and sending it into Affinity CRM.
Typical workflows include sourcing a prospect list that must satisfy several conditions at once, such as size, recent projects, certifications and active hiring, then enriching each row with researched answers. Investors use batch reports and market analyses to build theses, and the Data Room section offers public datasets indexed live. The recently launched Grip product targets outbound that AI agents can run. Docs, a product blog, customer stories and a plans-and-credits page are listed for evaluation, and an API key is the starting point for developers.
