Wojcicki Sisters Launch Healthcare Accelerator Fund

A new initiative seeks to address systemic challenges in American healthcare by bridging the gap between academic research and commercial application. Investor and former Google product manager Mary Minno announced the launch of Treehub, an early-stage startup accelerator, alongside its venture arm, the AI Health Fund. This dual structure is designed to support founders operating at the critical intersection of artificial intelligence and healthcare innovation.

The concept emerged from Minno’s personal experience late last year. Six weeks after having her second child, a family member was diagnosed with acute leukemia, deteriorating from perfect health to critical condition almost overnight. This crisis highlighted profound inefficiencies: difficulty finding specialists, long diagnostic wait times, and treatment delays caused by policy and outdated technology. “It’s only when people went outside of that system and broke the rules that things could happen,” Minno observed. This realization cemented her belief that challenging the status quo requires more startups capable of driving change.

To develop the concept, Minno turned to her longtime friend and former high school journalism teacher, Esther Wojcicki, educator and mother of the late former YouTube CEO Susan Wojcicki and 23andMe founder Anne Wojcicki. Their discussions centered on a common hurdle: academics with groundbreaking research often lack the skills to craft a compelling narrative for investors or to commercialize their discoveries effectively. Their solution was to create a program that pairs these researchers with seasoned operators, teaching them the essential art of building a business.

The resulting Treehub residency is a six-month program. The first 12 weeks are dedicated to helping founders achieve product-market fit, while the final 12 weeks focus on strategic company direction, which could involve raising a significant funding round, joining a traditional accelerator, or deploying a solution across a hospital system. Alongside the residency, Minno and Wojcicki partnered with Stanford University’s biomedical data science department to establish the AI Health Fund. This separate venture vehicle writes initial checks from $50,000 to $150,000 for academic spin-outs, aiming to back at least 60 companies. The fund has a $10 million target and made its first close last year at $1.5 million, backed by $500,000 from friends and family and a $1 million investment from billionaire VC Tim Draper.

Key advisors and partners include Anne Wojcicki as an operating partner, Esther Wojcicki as founding adviser, and a Stanford team featuring assistant professors Roxana Daneshjou and Alexander Ioannidis. Minno’s husband, Derek, president of Point Capital, is also involved. The fund has already invested in 12 companies from the Treehub pipeline, including women’s health tracker Clair Health and a new venture from researcher Dennis Walls focusing on pediatric autism.

A defining feature of the Treehub model is its focus on the earliest possible stage, often engaging with founders before a legal company entity exists. “In more than half the cases, we introduce the founders to the lawyers that helped them incorporate, so we almost play a co-founder-like role,” Minno explained. This hands-on, strategic support differentiates it from other accelerators. “We’re really helping them strategize and to get along well; when there’s a problem, we help them with problem-solving skills,” Esther Wojcicki noted.

The program is deliberately flexible, built to adapt to founders’ specific needs, whether arranging key introductions or providing scaling support. It notably forgoes a standardized demo day, recognizing that companies mature at different rates. Currently in an experimental phase, the team is evaluating which aspects of the accelerator-fund approach can be scaled and which should remain intimate. The ultimate vision is ambitious. “Our vision is to 10x it,” Minno stated. “We’re starting with something very small and then our plan is, after we run this cycle a few times, hopefully do this across the country.” The core mission remains ensuring the success of every company they work with, proving a new model for healthcare innovation can thrive.
