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. If a page is about you, link your account from it to write the about and set the links yourself. For a photo, a correction or to have a page removed, write to privacy@anchorterminal.com.
