Midi Health Surpasses $1B Valuation, Igniting a New Era for Women’s Health

Midi Health, providing the healthcare women in midlife deserve, rooted in science, guided by experts, and covered by insurance, led by Joanna Strober, Kathleen Jordan MD, Mindy Goldman MD, Sharon Meers, Melissa Waters, Jill Herzig, Jake Ramanathan, Matt Cook, and others, announced it raised $100 million in a Series D financing round led by Goodwater Capital with participation from new investors Foresite Capital and Serena Ventures, as well as continued support from Advance Venture Partners, GV (Google Ventures), Emerson Collective, SemperVirens, and McKesson Ventures. The round values the company at over $1 billion, marking a pivotal moment for a long-ignored segment of healthcare. The company has expanded its executive team with three key hires: Jason Wheeler (CFO), formerly of Tesla and Google; Melissa Waters (CMO), with leadership experience at Meta, Lyft, and Hims & Hers; and Matt Cook (CCO), previously at Omada Health and Firefly Health.

“This validates the movement to deliver better healthcare for women,” said Joanna Strober, co-founder and CEO of Midi Health. “Women’s health has been an afterthought for too long. This funding lets us change that at scale.”

Midi was founded to close some of the most persistent and costly gaps in women’s healthcare. Each year, two million women in the U.S. enter menopause, yet symptoms often go untreated, driving an estimated $25 billion annually in medical costs and lost productivity. Addressing menopause care, alongside the broader gaps women face across their lifespan, represents a massive opportunity: closing these gaps could add nearly $295 billion to the U.S. economy by 2040.

Midi has become a leading, scalable women’s health platform, now reaching more than 45 million women through nationwide insurance coverage and serving over 25,000 patients each week across a broad range of specialties.

AI sits at the core of the platform, enabling personalized care, streamlined operations, and continuously improving clinical outcomes. From tailoring care plans through intelligent chart analysis to automating scheduling, triage, and documentation, Midi uses AI to scale expert-led healthcare efficiently.

“Goodwater is committed to Midi Health’s mission to transform women’s healthcare,” said Eric Kim, co-founder and managing partner at Goodwater Capital. “Midi’s rapid growth reflects the strength of its care model, patient-first approach, and AI-driven personalization at scale.”

Midi’s care model, combining clinical expertise, technology, and data, has delivered clear improvements in women’s health outcomes, including a 28-point increase in breast cancer screening adherence, an 11-point increase in colorectal cancer screening adherence, and up to 13% lower total cost of care versus a matched comparison group. Patient data also shows meaningful reductions in A1c and LDL levels.

“When women founders and women customers are heard, entire systems change,” said Serena Williams, managing partner at Serena Ventures. “Midi is delivering essential care at scale in a category representing billions in healthcare spend.”
