Plato Technologies, Inc. said Wednesday it raised $16 million in a Series A round led by Nava Ventures, with participation from Gradient Ventures, Transpose Platform and Mustafa Suleyman, the CEO of Microsoft AI, who invested personally. The San Francisco startup builds simulated workplaces where AI agents practice real jobs before developers put them to work.
The round brings Plato's total funding to $19 million, according to the company's Oct. 28 press release. It did not disclose a valuation, and rivals in the same category are already raising and spending at a considerably larger scale.
What Plato builds
The company describes its product as "simulated workplaces where AI can learn to do real jobs." Each environment reproduces the tools, decisions and constraints of a given task, and is used to train and evaluate models and agents in contained settings, according to the release.
The Next Web reported that early focus areas include customer support, finance and accounting, HR and people operations, and healthcare administration. The appeal, in theory, is that AI labs can train and test agents without exposing live money or records to mistakes.
Plato's evaluations also examine process, not only outcome. The release said they test whether a model "followed instructions, respected constraints, and completed the task," and they flag reward hacking, a failure in which an agent games its scoring rather than doing the work. A purchase that blows the budget, for example, does not count as a success.
"Mastering real complex work comes from experience doing those tasks," CEO Robert Farlow said in the release. "We're building simulations that capture the tools, decisions, and unexpected situations those tasks involve, so AI models can gain experience in safe, contained environments before developers put them to work."
Investors and use of funds
Freddie Martignetti, founder of Nava Ventures, is joining Plato's board. Gradient Ventures led the company's earlier seed round, per the release, which gave neither the date nor the amount of that financing.
Plato said it will expand its library of real-world work simulations, pay professionals to recreate their jobs as simulations, and deploy AI agents on real tasks to collect additional experience.
"Robert and Pranav are deeply talented researchers and developers from Waterloo and Georgia Tech," Martignetti said in the release. He said the founders "have developed a unique way to create high fidelity environments at scale," and that Nava "quickly learned that Plato is really a data lab."
