Jessica Mah | Youngest YC Founder

Jessica Mah is the founder of inDinero and Mahway, a venture studio backing companies in aerospace, legaltech, and biotech. We discussed growing up in Westchester to immigrant parents, teaching herself to code at 10, and burning out from her first startup by 14. At 15, she dropped out of high school, enrolled in college, and later founded inDinero through Y Combinator at just 19 — at the time, the youngest female founder accepted. We covered her early struggles with retention, laying off most of her team, and rebuilding inDinero from the ground up. In her early 20s, she was on the cover of Inc. magazine and deemed “female Mark Zuckerberg". Later, Jessica stepped down as CEO after realizing she was miserable despite the company’s success. That shift led her to start Mahway — her “dream job”. Today, she lives radically transparently, races cars, flies planes, and redefines what it means to play the long game.
