CollectiveX (CX) announced a $3.2M oversubscribed pre-seed round on October 13, 2026, as it emerged from stealth. Council Capital and Anthemis Female Innovators Lab Fund co-led the round. SoGal Ventures, Emerson Collective, Muse Capital, and Segal Ventures also participated.
CX is a B2B platform. It turns peer-reviewed research and female-specific data into a structured, auditable intelligence layer that customers license via API. The company says it cites its sources every time, and that it can serve as a product’s full women’s health database or validate an existing one. Founding customers Human Powered Health and Altra Running are live on the platform.
The company’s pitch rests on a research gap. Women were not required in NIH-funded clinical trials until 1993, and CX says AI models trained on that research default to male data. It also cites a recent benchmark in which leading AI models failed 60% of women’s health questions. CEO Lindsey Abramo said less than 9% of NIH funding reflects women’s health.
Dr. Stacy Sims, an exercise physiologist who previously led sex-differences research at Stanford, co-founded CX and serves as Chief Research Officer. Abramo is CEO, and Angelica Marden is Chief Brand Officer. CX’s Research Lead Collective, headed by Sims, includes more than 20 MDs and PhDs who vet the research base. A grant program for those researchers launched with a $200,000 commitment from Momentous.
The funding will deepen the research across life stages and conditions, expand the intelligence layer, and scale early enterprise demand.
