Tom Siegel is the co-founder and CEO of TrustLab, a San Mateo company building independent technology to detect and measure harmful online content. He spent roughly 15 years at Google, where he founded and scaled the company's first Trust & Safety team into the industry's leading abuse-fighting organization, protecting billions of users. In 2020 he left to build the external referee he felt the internet was missing - a third party that measures disinformation, hate speech, and AI-generated harm without a platform's conflict of interest. TrustLab was chosen by the European Commission to run the first independent measurement of disinformation under its Code of Practice.

Co-author of 'Out of Office' with Anne Helen Petersen, Warzel writes from Lummi Island, Washington, with a voice that is analytical, empathetic, and stubbornly resistant to easy narratives.
