Background
Andrew Dudum is a Palestinian-American entrepreneur, angel investor, and the founder and CEO of Hims & Hers Health, Inc. (NYSE: HIMS), a telehealth company 1. He was born in 1988 and raised in San Francisco, California 2. Dudum trained as a classical cellist and performed across the United States and Europe, including at Carnegie Hall 1.
Dudum attended the Wharton School at the University of Pennsylvania, studying Management and Economics with concentrations in entrepreneurial management and venture capital, though he did not complete his degree 13. While at Wharton, at age 19, he co-founded LendforPeace, a nonprofit micro-lending platform that funded small business loans of $200 to $2,000 primarily in the Middle East 13.
After leaving Wharton, Dudum worked at TokBox, a Sequoia-backed video-chat startup that was later acquired 23. In 2013, he co-founded Atomic Labs (now Atomic) with friends from Wharton, a San Francisco-based startup studio backed by investors including Peter Thiel and Marc Andreessen 13. As General Partner at Atomic, Dudum played an integral role in developing companies including Bungalow, Homebound, TalkIQ, and Terminal 4.
In 2016, Dudum founded Hims as part of the Atomic portfolio, alongside Jack Abraham and Hilary Coles 1. The company launched as a direct-to-consumer men’s telehealth brand and expanded into women’s health under the Hims & Hers brand. Hims & Hers went public via SPAC in January 2021 at a $1.6 billion valuation, trading on NYSE under the ticker HIMS 52. As of 2024, the company had a market capitalization of approximately $4 billion 2.
Beyond Hims & Hers and Atomic, Dudum is an active angel investor and advisor to more than 24 startups 4.
Stated Thesis
(Self-reported: These represent what Dudum says publicly about his approach. See Inferred Thesis for analysis of actual investment behavior.)
Dudum’s investing and advising philosophy centers on high-impact intervention at critical moments. He has stated that when he advises startups, it is at key inflection points: fundraising, bringing on board members, recruiting struggles, or pivots. He described these as “high-value moments that as an investor or advisor you can have a big impact on” 4.
On learning, Dudum has advised founders to “try to learn from as many smart people as possible. The best way to learn is through osmosis. Suck as much value from their brain and get it into your brain as quickly as possible” 5.
On choosing investors, he has emphasized the importance of picking the right partners: “The people you bring in fundamentally matters because at some point, things are going to be very ugly. It’s going to be brutal. And you, as a founder or as an entrepreneur, actually are going to need to rely on your investors for guidance or, in a lot of situations, just encouragement” 5.
Dudum is a strong advocate for proactive fundraising: “As a CEO, your number one goal, make sure you don’t run out of money. One of the pieces of feedback that I always encourage founders on is to be proactive about raising money far before you need money” 5.
