Deeptune builds high-fidelity digital "sandbox" environments where AI agents can practice complex tasks via reinforcement learning. Its platform creates simulated worlds intended to let agents convert raw model capability into reliable task performance, with example tasks including managing financial books or inboxes. The company emphasizes a sandbox architecture to give agents experiential training in controlled settings. Deeptune is led by a team with backgrounds at Anthropic, Scale AI, Palantir and Glean. Following the Series A, the company has $43 million in new funding to expand engineering and operations and to accelerate development of its simulation infrastructure.
