SAN FRANCISCO, Oct. 13, 2026 — Collective X Health emerged from stealth today with an oversubscribed $3.2 million pre-seed round co-led by Council Capital and Anthemis Female Innovators Lab Fund, with participation from SoGal Ventures, Emerson Collective, Muse Capital and Segal Ventures. The B2B women’s health intelligence platform is live with founding customers Human Powered Health and Altra Running, which are licensing CX’s female-focused research and data via API to power health, performance and recovery insights.
Why Collective X Health was built
Women were not required to be included in NIH-funded clinical trials until 1993, and the research that informed many AI models has defaulted to male data, the company says. That history contributes to misdiagnosis, ineffective care and guidance that does not fit women’s bodies. Collective X Health cites a recent women’s health benchmark in which leading AI models failed 60% of questions.
“Women have been systematically excluded from health research, with generational consequences,” said Dr. Stacy Sims, Ms and PhD, Co-Founder and Chief Research Officer of CX. “We pair vetted academic research with commercial scale, so companies, clinicians, and health and performance products can finally build on data designed for and from female bodies.”
What Collective X Health does
Collective X Health turns peer-reviewed research and female-specific data into a structured, auditable intelligence layer that is licensed through an API. Unlike general-purpose AI, CX says it cites its sources for every insight, ensuring each recommendation or signal is research-backed. The platform can serve as a product’s entire women’s health database or validate an existing one.
“Women’s health isn’t a niche market. It’s half the population, yet less than 9% of NIH funding reflects that,” said Lindsey Abramo, Co-Founder and CEO. “Every company claiming to serve women should be able to show the research behind that claim.”
“Collective X’s edge isn’t a smarter model. It’s a smarter foundation underneath the model,” said Elizabeth Davis, Partner, Anthemis Female Innovators Lab Fund.
Where Collective X Health stands today
CX’s scientific backbone is its Research Lead Collective, led by Dr. Stacy Sims and comprising more than 20 globally recognized MDs and PhDs who hand-vet the research base and the platform’s intelligence. Research Leads are also eligible for a growing grant program launched with a $200,000 commitment from human performance company Momentous to help close the gender data gap in sports science and to drive new research in women’s health.
The company has research and data partnerships with academic journals, Open Medicine Foundation, WildAI and Eternal, and says it has a pipeline of more than 50 prospective partners. CX will use the pre-seed funding to deepen research across life stages and conditions, expand its intelligence, rapidly scale early enterprise demand and drive new research in women’s health.
Leadership and advisors
Collective X Health was co-founded by Dr. Stacy Sims (Chief Research Officer), Lindsey Abramo (CEO) and Angelica Marden (Chief Brand Officer). Abramo previously led commercial teams through two acquisitions at POPSUGAR and Group Nine before leading World of Good Brands (Well+Good, LIVESTRONG) through its sale. Advisors include Mel Strong (Next Ventures), Dorothy Kilroy (Oura), Anne Bradley (Honey Mirror) and Amber Taylor (Les Mills).
“Not only do we believe that CX becomes the foundation that everyone else’s product relies on for evidence based women’s health insights, but this is the team to build it: with their combination of scientific rigor, product expertise, and years of women’s media distribution to reach every woman where she is,” said Rachel Tsui, Partner at Council Capital.
