Introduction
Company data built from what every company says about itself.
CompanySpec turns company websites into structured data you can search and look up by API (an MCP server is coming soon). For each company you get what they do, who they sell to, their technologies and vendors, compliance claims, hiring, recent hires, funding and news, plus summaries of key pages like pricing, legal and careers.
What you can do
Find companies by who they sell to
"Practice management software for independent dental practices." One query, filters on top.
Look up a company
Basic profile by domain, with optional paragraphs for ICP, pricing and description.
Find lookalikes
Up to 10 seed companies in, similar companies out, with a similarity score.
Track hiring
Open job postings and recent hires by department and seniority.
How billing works
Each company costs at most once a month: one lookup if you name it, or one discovery if we find it for you. After that, everything about it is free for the rest of the month: its ICP (who they sell to), pricing summary, page summaries, technologies, headcount, recent hires, funding, news and job postings.
