The landscape of reproductive health is evolving rapidly, with growing concerns about data privacy and access to unbiased healthcare information.

In response to these challenges, Comma, a female-founded integrated period care company, is stepping up with innovative solutions.

The Nashville-based company recently announced a $2 million seed funding round alongside the official launch of Sara™, a secure period tracking app designed to empower users with personalized reproductive health insights.

About Comma

Comma is a reproductive health company dedicated to revolutionizing period care through cutting-edge technology, sustainable products, and advanced diagnostics.

Founded by experts in reproductive health and cybersecurity, Comma is committed to delivering personalized, predictive, and secure healthcare solutions.

At the heart of its innovation is Sara™, a hyper-secure period tracking app designed to protect user data with HIPAA-based privacy standards.

Sara™ empowers users to track their menstrual health, identify patterns, and connect with trusted care providers—all while ensuring the highest level of data security and autonomy.

Beyond software, Comma is reshaping menstrual care with biodegradable period products and groundbreaking research into menstrual blood diagnostics.

With a mission to transform reproductive health, one period at a time, Comma is building a safer, smarter, and more sustainable future for menstrual care.

Secure, Predictive Reproductive Health Technology

With reproductive rights facing uncertainty, Comma aims to set a new standard in menstrual health by integrating secure technology and sustainable consumer products.

Led by a team of reproductive health and cybersecurity experts, the company has spent two years developing cutting-edge technology and consumer products that prioritize autonomy, security, and innovation.

After successfully completing the Techstars Physical Health accelerator program in 2023, Comma attracted a diverse group of investors, with more than 50% of its seed investors being women—a testament to its mission of centering those most impacted by reproductive health challenges.

"Comma is approaching menstrual health in a holistic way that hasn't been done before in the consumer products and technology space," said Trey Bowles, Managing Director of Techstars Physical Health. "We're proud to invest in a more secure, sustainable future through this partnership."

Introducing Sara™: The Future of Secure Period Tracking

With this funding, Comma has officially launched Sara™, its flagship product designed to offer secure period tracking and disease detection.

Now available for public use, Sara™ helps users uncover patterns in their menstrual cycle, detect potential concerns, and connect with relevant care providers.

Unparalleled Data Security in Period Tracking

One of the biggest differentiators of Sara™ is its focus on data security and privacy. Unlike many period tracking apps that may share user data with third parties, Comma believes that period data is personal health information—just as valuable as clinical trial findings or laboratory test results.

To safeguard user data, Sara™:
✅ Implements HIPAA-based security standards
✅ Uses industry-leading privacy protocols
✅ Operates as a Progressive Web App (PWA)—accessed via an internet browser instead of an app store, ensuring that user metadata remains untracked

"People shouldn't have to choose between a better understanding of their bodies and the threat of surveillance," said Miller Morris, M.A., M.P.H., founder and CEO of Comma. "That is why we built Comma with security and autonomy at the forefront. Even as policies restricting reproductive rights surface, we remain committed to protecting user data and building community. Consumers deserve better, period."

Beyond Period Tracking: A Holistic Approach to Reproductive Health

Comma’s innovation doesn’t stop at period tracking. The company is pioneering new ways to utilize menstrual blood for reproductive health screening and is committed to sustainability with the development of biodegradable single-use period products.

Advancing Menstrual Health with Cutting-Edge Science

• Revolutionary Diagnostics: Comma plans to launch a send-back diagnostics service, allowing users to send used period products to the lab for analysis. This initiative could lead to new breakthroughs in identifying menstrual blood biomarkers for reproductive health conditions.
• Sustainable Period Products: Comma is developing the first-ever biodegradable single-use tampon with a compostable plant-based bio-resin applicator and 100% organic cotton, making menstrual care more eco-friendly.
• Industry Leadership: With two Comma team members serving on the ISO/TC 338 (the International Standards Organization committee for menstrual products), the company is helping to set new global standards for sustainable and effective period care.
