Alex Aravanis is the CEO and co-founder of Moonwalk Biosciences, a precision epigenetics company he launched in 2024 with $57 million and Broad Institute scientist Feng Zhang. An engineer-turned-physician with degrees from UC Berkeley and Stanford, he co-founded the cancer early-detection company GRAIL, later returned to Illumina as Chief Technology Officer, and now wants to rewrite the 'software of the genome' without cutting a single strand of DNA.

Joe Betts-LaCroix is the co-founder and CEO of Retro Biosciences, a San Francisco longevity biotech on a mission to add 10 healthy years to the human lifespan. A scientist-turned-serial-entrepreneur who once held a Guinness World Record for building the world's smallest Windows PC, he now leads a company backed by OpenAI's Sam Altman, valued at $1.8 billion in 2026, that has run an Alzheimer's clinical trial and co-developed a longevity-focused AI model with OpenAI. He came to biology by an unlikely route: a D-average high schooler who tinkered in shared houses, then earned straight A's, transferred to Harvard, and did research at MIT and Caltech before co-discovering principles of electron transfer in proteins.
