Lance Co Ting Keh

Lance Co Ting Keh founded OpenPay, an AI subscription company acquired by Airwallex in 2025, and today is the co-founder, CEO of t0.ai and a GM at Airwallex. He is a builder at heart: he co-founded Vega Health, a Duke spinout in health AI, and earlier bootstrapped SharedRoof Investments, a real estate company that valued homes off predicted prices, and co-founded a sports analytics shop.

Based in our Silicon Valley office, Lance focuses on early-stage applied AI, leading technical diligence and incubating new companies. He serves on the boards of Vega Health and ChipAgents, which builds AI for chip design.

Lance led engineering for two teams at Google X working on AI drug discovery and computer vision, was the second engineer at Cresta building language models for contact centers, and helped start the machine learning team at Box, well before the current surge in deep learning.

He earned bachelor's and master's degrees in electrical engineering and computer science from Duke University, where he was an A.B. Duke Scholar. He lives in Portola Valley with his wife and two children, and maintains that his best athletic days are ahead of him, a position he has held for almost a decade.
