After 28 years in automotive electronics, Marc Bolitho left the predictable road for a semiconductor startup - then redirected that startup when ChatGPT changed the map. His operating idea is simple enough to remember: stay level, work as one team, and follow the economics all the way down to the math.

A teenage encounter with Bitcoin taught Michael Gao what specialized silicon could do. Now he is trying to give zero-knowledge proofs and advanced cryptography a computer architecture of their own.

The Visibl Semiconductors co-founder went from a Queen’s boat-sharing pitch to software for chip teams - with a podcast microphone, an Intel veteran and one stubborn bottleneck along the way.

He built the guts of phones nobody could see inside, then spent 25 years learning to explain the chips that quietly run everything. Now he sells Marvell's silicon to the companies building the AI cloud.
