About this list

What "stealth" means here: the person's current job is a founder title (Founder, Co-Founder, Founder & CEO…) at a company listed as "Stealth", "Stealth Startup" or similar, because they haven't announced it yet.

Where it comes from: public professional profiles, via the Crustdata API. A new search runs every week and adds whoever newly matches. Profiles can take a few weeks to show up, and start dates are by month.

The company on each row is the most recent job before going stealth, with the title they held there. Where we can, we skip internships, advisor seats and freelance stints. On a "former employer" page it shows the job at that employer instead. Click a row for their full work history and education.
