Healthcare Sales - B2B

Collective X Health launches with a $3.2 million pre-seed round to close the women's health data gap. Oct 13, 2026, 13:00 ET Co-founded by Dr. Stacy Sims, the B2B platform powers smart health and performance brands with research-backed insights built on female physiology. It is live today with founding customers Human Powered Health and Altra Running. SAN FRANCISCO, Oct. 13, 2026 /PRNewswire/ - Collective X Health (CX), a women's health and performance intelligence platform, announced today it has emerged from stealth with a $3.2 million oversubscribed pre-seed, co-led by Council Capital and Anthemis Female Innovators Lab Fund, with participation from SoGal Ventures, Emerson Collective, Muse Capital, and Segal Ventures. Founding customers are licensing CX's women's health intelligence via API to power accurate health, performance, and recovery insights all built on bias-corrected female research and data. Why CX Was Built Women weren't required in NIH-funded clinical trials until 1993, and the AI models now trained on that research default to male data, leading to misdiagnosis, ineffective care, and advice that doesn't fit women's bodies. Companies adding cycle tracking, hormonal insights, and AI-assisted care lack a trusted source of women's health evidence to build on, and leading AI models failed 60% of questions on a recent women's health benchmarks. "Women have been systematically excluded from health research, with generational consequences," said Dr. Stacy Sims, Ms and PhD and 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 CX Does CX 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 cites its sources every time, ensuring that every single insight is research-backed. CX 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. "Instead of every wearable and health platform trying to solve the same research problem on its own, CX gives the entire women's health ecosystem an evidence layer to build on." Where CX Stands Today CX's scientific backbone is its Research Lead Collective, a group headed up by Dr. Stacy Sims and more than 20 globally recognized MDs and PhDs who hand vet CX's research base and 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 drive new research in women's health. CX has research and data partnerships with academic journals, Open Medicine Foundation, WildAI, and Eternal, a pipeline of more than 50 prospective partners. CX will use this funding to increase the depth of its research across every life stage and condition, expand its intelligence, rapidly scale early enterprise demand, and drive new research in women's health. Leadership CX is led by co-founders Dr. Stacy Sims, Chief Research Officer; Lindsey Abramo, CEO, who led commercial teams through two acquisitions at POPSUGAR and Group Nine before leading World of Good Brands (Well+Good, LIVESTRONG) through its sale; and Angelica Marden, Chief Brand Officer, veteran women's wellness media executive and brand builder. 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.
