The Fund That Bets on 30 Companies and Backs Teenagers

Deeptune
Deeptune is a New York AI company that builds high-fidelity simulation environments - 'training gyms' - where AI agents practice real digital work such as accounting, customer support, DevOps, and spreadsheet and CRM tasks before being deployed. Its reinforcement-learning environments recreate the day-to-day software of roles like accountants, lawyers, and engineers so agents can learn multi-step 'computer use' the way a pilot trains in a flight simulator. Founded in 2025 by Tim Lupo and Lukas Schmit, Deeptune raised a $43M Series A led by Andreessen Horowitz in March 2026 and was acquired by AI unicorn Mercor in July 2026.
