I love to solve hard technology problems that make people's lives better. That led me to build Forethought at the start of the AI wave — agentic AI powering over a billion customer interactions a month, acquired by Zendesk — and now Espa Labs, the AI executive assistant that helps everyone achieve more. I'm also going deep on quantum computing — which will be the next technological wave.
