Peak Ji (季逸超) is a Chinese AI researcher and entrepreneur who served as co-founder and chief scientist of Manus, the general-purpose AI agent that launched in March 2025 and drew viral attention including from Twitter founder Jack Dorsey within days of release . He joined the Manus team from ZhenFund, where he had been Entrepreneur in Residence (EIR) and helped review technical details for the firm's public analysis of DeepSeek R1 . In his product thinking, Peak habitually asked whether any technical feature could generate network effects within the product—a framing he applied to Manus's architecture as a general agent . In December 2025, ZhenFund announced that the Manus team, including Peak, had joined Meta . Earlier in his career, he had worked on replicating OpenAI's o1 model as a personal project, documenting the effort in a technical report published through ZhenFund in October 2024 .
