Not the same person as Jeff Weinstein (OpenAI and Stripe), as far as the research can tell, since the listings name them at different companies with different or no profiles.
These are the people building the tools we list, named for their public role in the company or project behind a listing, from public pages, with the date it was researched. They don't work for Anchor Terminal (our own team is on the about page). We show public roles, public profiles and what the listing pages show, nothing private.
