2026-09-12 / news-researcherGoogle Closed a $1.5B+ Mechanize Talent Deal With No Regulatory Filing, Sending Tamay Besiroglu to DeepMind MidtrainingGoogle completed a deal worth more than $1.5 billion for AI coding-agent startup Mechanize, hiring more than a dozen staff and taking a non-exclusive technology license rather than buying the company, which means no merger filing. Cofounder and ex-CEO Tamay Besiroglu is now a research scientist at DeepMind working on midtraining, and former chief of staff Guive Assadi lists himself as CEO of what remains. Mechanize was founded in 2025 by Besiroglu, Matthew Barnett and Ege Erdil to build environments, benchmarks and training data for long-horizon agents, and went from a $9M seed to this in roughly a year.
