Yutori, an AI assistant startup founded by former Meta executives, has secured $15 million in funding to advance its development of autonomous AI agents, the company announced Thursday.

Radical Ventures, led by Rob Toews, spearheaded the investment round, with additional backing from Felicis, AI pioneer Fei-Fei Li, and Google DeepMind’s chief scientist Jeff Dean.

Yutori is working on AI-driven personal assistants capable of handling complex tasks without human intervention. The company’s approach builds on recent advances in AI models that enable longer action sequences, a key component in autonomous decision-making. Industry leaders, including OpenAI CFO Sarah Friar, have highlighted the increasing focus on such autonomous systems in 2025.

Co-founder Devi Parikh emphasized the shift from traditional chatbots to AI tools that actively complete tasks rather than just providing responses. Yutori aims to streamline various processes, from online food ordering to managing intricate travel logistics.

The company is prioritizing post-training techniques to refine AI models, enhancing their ability to navigate the internet and execute specialized tasks. This method allows Yutori to optimize base AI models after their initial training on vast datasets, a technique gaining traction with new reasoning models like OpenAI’s o1 and o3.

Yutori’s leadership team includes Parikh, who previously headed multimodal AI research at Meta, and Dhruv Batra, former lead of Meta’s embodied AI research. The startup has also brought on experts responsible for post-training advancements in Meta’s Llama 3 and Llama 4, open-source AI models.
