CollectiveX Health Launches With a $3.2 Million Pre-Seed Round to Close the Women's Health Data Gap

CollectiveX Health, a women's health and performance intelligence platform, led by Lindsey Abramo, Stacy Sims, PhD, and Angelica Marden, has emerged from stealth with a $3.2 million oversubscribed 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.

CX was built to address gaps in women’s health research, where historical underrepresentation in clinical trials has contributed to male-biased datasets used to train AI models. These gaps can lead to misdiagnosis and ineffective care, while the lack of reliable women’s health evidence limits companies developing cycle tracking, hormonal insights, and AI-assisted care. A recent benchmark study also found that leading AI models failed 60% of questions on women’s health.

"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."

CX converts peer-reviewed research and female-specific data into a structured, auditable intelligence layer accessible through an API. Each insight is backed by cited sources, enabling companies to use CX as their primary women’s health database or to validate existing datasets.

"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."

CX’s scientific foundation is its Research Lead Collective, headed by Dr. Stacy Sims and comprising more than 20 MDs and PhDs who vet its research base and intelligence. The collective is supported by a grant programme launched with a $200,000 commitment from human performance company Momentous to address the gender data gap in sports science and advance women’s health research.

CX has established research and data partnerships with academic journals, Open Medicine Foundation, WildAI and Eternal, alongside a pipeline of more than 50 prospective partners. The funding will support research expansion across life stages and conditions, strengthen its intelligence platform, scale enterprise demand, and advance new research in women’s health.
