    The hot takeJeff's read on Sumsub

    There is SO much to like about this company, starting with the very first line on their careers page: "Trust over control. We hire smart people and let them shine. No micromanaging, no games—just trust, ownership, and great work." This is EVERYTHING that you look for in a company. They are all about output over attendance, they don't micromanage, they have strong Glassdoor reviews, and a MOSTLY clear remote work policy.
