Co-founded by women’s health researcher Dr. Stacy Sims, the startup is launching a B2B intelligence platform that helps health technology, wearable, and performance brands deliver insights grounded in female physiology.

Collective X Health (CX), a women’s health and performance intelligence startup, has emerged from stealth with $3.2 million in oversubscribed pre-seed funding to address a longstanding problem in healthcare and health technology: the lack of research and data specific to women’s physiology.

Council Capital and Anthemis Female Innovators Lab Fund co-led the financing round, with participation from SoGal Ventures, Emerson Collective, Muse Capital, and Segal Ventures.

The company launches with founding customers Human Powered Health and Altra Running, which are licensing its women’s health intelligence through an application programming interface (API) to develop more accurate health, performance, and recovery insights.

A History of Female Exclusion

Women were not required to be part of NIH-funded clinical trials until 1993. That has left a legacy of research limitations that continues to influence healthcare technologies and artificial intelligence.

Because medical research disproportionately relied on male participants, significant gaps in understanding women’s health resulted.

Collective X Health aims to address decades of disproportionate reliance on male participants.  Its goal is to provide a scientifically validated foundation for companies developing women’s health products.

Dr. Stacy Sims, Co-founder and Chief Research Officer of Collective X Health, explained the company’s key approach, stating, “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,” said

The challenge has grown increasingly urgent as wearable devices, digital health platforms, and AI-powered health applications reach more female consumers.

Building Research-Backed Women’s Health Intelligence

Collective X Health operates as a B2B intelligence infrastructure platform. It turns peer-reviewed research and women-specific data into structured, auditable information accessible via an API.

Its technology lets wearables, digital health companies, sports teams, and performance brands integrate evidence-based recommendations into existing products without building comprehensive women’s health research databases from scratch.

A distinguishing feature is the platform’s ability to cite research supporting its insights, offering transparency that general-purpose AI systems may lack.

“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.”

Abramo’s background spans media and digital brand development at POPSUGAR, Group Nine, and World of Good Brands, and Chief Brand Officer Angelica Marden, an experienced women’s wellness media executive.

Scientific Foundation

Collective X Health’s research foundation is supported by a Research Lead Collective comprising more than 20 internationally recognized physicians and PhD researchers led by Dr. Sims.

An internationally recognized exercise physiologist and nutrition scientist, Sims previously conducted sex-differences research at Stanford University and directed female athlete research at AUT University and the University of Waikato. She has published more than 100 peer-reviewed papers and authored ROAR and Next Level.

The company has established research and data partnerships with academic journals, Open Medicine Foundation, WildAI, and Eternal.

Human performance company Momentous has also committed $200,000 to a research grant program that supports efforts to close the gender data gap in sports science and women’s health.

Future Goals

The new funding will expand research coverage across women’s life stages and health conditions. Other key goals include strengthening its intelligence platform, accelerating enterprise adoption, and supporting additional research.

With more than 50 prospective partners in its pipeline, Collective X Health is positioning itself as foundational infrastructure for the expanding women’s health technology sector.

For investors and entrepreneurs, its emergence highlights an opportunity at the intersection of women’s health, artificial intelligence, sports science, and enterprise health technology.

It is where improving data quality could reshape how companies develop products and services for women.
