Mary Minno first met Esther Wojcicki when she was 15.
Walking into Wojcickiās journalism class at Palo Alto High School, she was new to Silicon Valley. About 20 years later, Minnoās still in the areaāand after nearly a decade in Big Tech, most recently at Google, sheās teaming up with her former teacher. Wojcickiāoften called the Godmother of Silicon Valleyāhas joined Minno to launch Treehub, a residency program focused on academic founders in biotech and healthcare.
āOur idea is to bridge labs-to-launch for the best and brightest computational health builders out of academic circles,ā said Minno, who became interested in healthcare amid the trials of her last pregnancy and the difficult diagnosis of a loved one. āI became a little bit problem-obsessed. And Iām a student of Estherās: I believe in iterating on things until theyāre correct. I couldnāt believe that we can let the healthcare system operate the way it does. All of us wind up in that bed one day.ā
Wojcicki is famous for her āfail fast and reviseā philosophy, and her 2019 book How to Raise Successful People. (All her daughters have become leaders in tech and medicine, including late YouTube CEO Susan Wojcicki and 23andMeās Anne Wojcicki. The least well-known of the three, Janet, is a leading UCSF anthropologist and epidemiologist.)Ā
āAll learning involves failure,ā said Wojcicki. āYou just need to do it again and do it again until you get it right⦠You couldnāt get a bad grade in my class. You could just revise until you got it right, because all these mistakes that people were making were just examples of them just not knowing it⦠but when they revised, they understood it and they did it perfectly.ā
This ultimately applies to Treehub, which is backed by the AI Health Fund thatās deploying $10 million over the next 18 months into founders straight out of academia (and who will have to, presumably, fail fast and revise). So far, Minno and Wojcicki have invested in 12 companies, including Clair Health, which is looking to build the first continuous hormone monitor for women, and Nestwell, which assesses home health by tracking mold and chemical exposure. The residencyās backers so far include venture capital OG Tim Draper and Anne Wojcicki, who told Fortune via text that itās the right time for something like this.Ā
āWeāre in a window right now where AI can fundamentally reshape the healthcare industry, but only if the founders with the science are given the capital and mentorship they need to succeed,ā Anne wrote to Fortune.Ā
Treehub is indeed emerging in the context of a broader moment in the AI boom around healthcare, where thereās an extremely high level of optimism among founders and investors about the changes AI could reasonably bring about. Thereās also an urgent sense that the time between academia and commercialization can compress.
āThings stay in academia for far too long,ā said Minno. āWe can and need to commercialize these things faster, and we need to get people healthier more rapidly.ā

Cursorās $60 billion opportunity⦠Last night, news dropped that Cursor and SpaceX have been working together and that Muskās rocket-maker could buy the company for as much as $60 billion. Itās a complex but interesting answer to the question I asked in my last magazine feature: What will become of Cursor? Read the story here.
