Research

Information on periods is outdated, biased, and unethically collected. We’re changing that. Whether you want to pilot new products or contribute your anonymous data to our scientific database, we want to co-create with you.


Become a catalyst

Our Genesis

Comma is revolutionizing women’s health by harnessing the power of periods. The only integrated menstrual health solution, we’re bringing autonomy, sustainability, and clinical science to menstruation.

 

Story

We want to create a  world in which menstruators (half the population!) have: 1) quality and secure data about their bodies; 2) the means to do something actionable with those data, and 3) access to reproductive health products and services they like and can afford--all in one place.

Future

Our first product is the first and only HIPAA-compliant period tracking app (2024) that links end-users to relevant care partners. We've also developed the first biodegradable tampon ( 2024), and bring together tech and product to engineer a new market category in menstrual diagnostics with our send-back program (2025). We want you to innovate with us.
