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.
Fleet AI, Inc.
Fleet AI is an applied research lab building training gyms for AI agents - high-fidelity simulation environments that model real work so frontier models can practice, fail, and learn under human supervision. The company partners with AI labs, hyperscalers, and enterprises to develop the next generation of embodied, drop-in virtual assistants.
