Menos AI has raised $5.1 million in Pre-A financing led by returning investor Copper Sky Capital, with participation from Alpha Square Group. The financing brings the San Jose-based company’s total funding to more than $10 million. Jack Selby, who is also managing director at Thiel Capital, led the investment on behalf of Copper Sky Capital.
Founded in 2024, Menos AI was co-founded by William J. Wu, Baojiang (Chris) Yang and Xiang Pan. Wu serves as CEO, Yang as Chief AI Scientist and Pan as CTO.
Menos AI develops AI infrastructure for institutional investors, including asset managers and hedge funds. Its platform connects proprietary research, market data, investment reasoning and workflows to support research, portfolio management and other investment operations.
The company’s Sonαr research agent operates within its AgentOS platform and is designed to bring internal research, third-party content and market data into a private, auditable environment. Menos AI publicly launched Sonαr in August 2025 and has since expanded its product offering around enterprise AI infrastructure for investment firms.
