Joe Betts-LaCroix

Cofounder, CEO

Joe Betts-LaCroix began as a scientist at Harvard, MIT, and Caltech. He was part of a three-person team at Caltech that first elucidated the factors governing electron-tunneling rates in proteins, which is published in journals such as Science and JACS, with over 1000 citations so far. His first venture-funded startup, OQO, created the world’s smallest windows computer (Guinness world record 2006) with a team of 110 people, more than 100 patents, and over 10,000 units sold; and was sold to Google. His second startup, Vium, automated animal research to accelerate medical research. Vium, as a team of 75 people, created thousands of advanced mouse cages that monitor environmental factors and HD video in each cage using computer vision + deep neural networks to determine whether experimental drugs are working against models of disease. Recursion Pharma acquired Vium in 2020 and IPO’d in 2021. Joe spent 2.5 years as a part-time partner at Y Combinator and has mentored and invested in numerous bio startups. Joe is presently CEO of his third venture-funded startup, Retro Biosciences, which is creating therapeutics against targets elucidated by its research in aging biology, with the mission of increasing healthy human lifespan by ten years.

VP of Operations

Trained in psychology, my work experience has been in Project and Operations management, specifically in onboarding complex R&D workflows. Before joining Retro I worked at Airbus R&D division (Acubed) where I wore a lot of different hats and learned that the more challenging the problem I have to solve, the more energy I feel. Building the operations team at Retro has so far been the most rewarding experience of my career, not only because of the complexity but also because of the sense of purpose toward Retro’s mission.
