TechFlow reported on October 28, citing a PR Newswire press release, that AI training environment company Plato announced the completion of a $16 million Series A funding round led by Nava Ventures, with participation from Gradient Ventures, Transpose Platform, and Microsoft AI CEO Mustafa Suleyman. Nava Ventures founder Freddie Martignetti will join the board. After this round, Plato's cumulative funding has reached $19 million; its previous seed round was led by Gradient Ventures.

Founded in 2025 and headquartered in San Francisco, Plato builds resettable, reusable simulated work environments for AI labs, covering roles such as customer support, HR operations, finance, accounting, and healthcare administration, for reinforcement learning training and model evaluation, avoiding real-world consequences from training models in live systems.
