David Yoon


I’m a technical founder and like to build products/companies with great teams working on meaningful problems. I advise/invest in companies via ylab and am exploring a new idea via SPC. I like working at the intersection of technology, academia, and government.

I was the CTO at Samasource (recruited by Charlie Cheever). I helped open the office in Nairobi and became active in the tech eco-system there. I’m a member of the local CTO community and helped start the local Ruby group and like working with companies/organizations in that region.

I worked on a bi-partisan immigration reform group with Mark Zuckerberg at FWD.us where I became the head of engineering. We launched advocacy/political tools to varying degrees of success. I got the chance to meet/learn from some of the best operators across both parties. Through that experience I got to serve on the faculty of UC Berkeley Haas where I lectured two courses at the intersection of technology and civics. I was an early core team member at USDR, partnering with Robin Carnahan to support counties/local governments in the early days of Covid and helped build their election worker management tool. I also helped launch projectN95.

Recently, I’ve been working in healthcare, first as the head of engineering at Antara Health. Then as an engineering director at Cityblock Health.

I started my career in New York, where I was an early engineer at Sparknotes and Cake and Arrow. I studied computer engineering/computer vision at McGill University.

Based between Amsterdam and San Francisco.
