Investing in AI and deep tech across the US and Asia. Chip architect turned investor.

About

I'm a General Partner at B Capital, where I back early- and growth-stage companies in AI and technology, from foundation models to robotics and semiconductors.

I started my career designing chips at AMD, then spent nearly two decades investing at TA Associates, Goldman Sachs and the SoftBank Vision Fund. Having built hardware myself, I like working with founders on hard technical problems.
