How this page is built
Startups are the private companies counted as startups (see our startup funding data), placed by the address on their latest Form D. Registered-agent and virtual-office addresses (common in Delaware and Wyoming) are not counted as a location. Public companies, foreign issuers and business-combination filings are excluded.
