Delivery Hero announced Herogen on April 24, 2026, an autonomous software delivery agent built in-house on multiple LLMs with a council-of-agents review layer before human sign-off. Herogen currently merges 100+ pull requests per day—equivalent to the annual output of 130 senior engineers—accounts for 9% of all company code change requests, and has freed an estimated 250,000 engineering hours annually. The agent carries an 85% merge success rate, is adopted by 18% of Delivery Hero developers, and targets 20% of all code changes by year end.
