As demand for realistic AI training grows, Deeptune raises $43 million to build simulated workplaces

Andreessen Horowitz invests $43 million in Deeptune, a startup that trains AI agents in simulated workplaces.

Deeptune builds simulated work environments where AI agents learn to handle multi-step tasks in software like Slack or Salesforce. CEO Tim Lupo compares the approach to flight simulators for pilots: instead of just learning from text, AI models practice in realistic replicas of workplaces, like those of accountants, lawyers, or software engineers. According to Fortune, Deeptune has already built hundreds of these environments for leading AI labs.

Andreessen Horowitz leading a $43 million funding round signals how seriously the industry takes this training method. Andreessen partner Marco Mascorro told Fortune that AI models are increasingly learning through interaction rather than human-curated data. According to ResearchAndMarkets, the global market for this type of AI training is expected to grow from $11.6 billion in 2025 to over $90 billion by 2034.
