Mercor Buys Deeptune in Its First Major Acquisition — a16z-Backed RL-Environments Startup That Foody Angel-Invested In 3 Months Ago at $43M Series A

Mercor, the $10B AI unicorn now at $2B in annualized revenue, has made its first M&A move — acquiring Deeptune, the a16z-backed startup that builds simulation environments where AI agents practice tasks in Excel, Salesforce, and Slack replicas before deployment. Terms weren't disclosed, but 23-year-old CEO Brendan Foody was an angel investor in Deeptune's $43M Series A just three months ago and told Fortune the future acquisition was 'in a lot of ways the main motivation, actually' for that investment. Deeptune's team relocates to Mercor's New York office; the deal targets rising demand from Anthropic and OpenAI for digital enterprise replicas used to train and validate frontier agents.
