Built for women, by women

Founded on the belief that every woman deserves better than guesswork about her body.

The founding moment

Phira emerged from a simple but powerful frustration: in a world powered by real-time intelligence, women are still left with hindsight, not insight.

Most women discover, at some point, that the tools available to them for understanding their own bodies are surprisingly primitive. Our options include calendar apps that are based completely on guesswork, daily temperature readings that can only confirm what has already happened, or urine tests that not built for long-term use.

Our mission

Our mission is to increase accessibility for every woman to be able to understand her own body so she can make decisions that serve both who she is today and who she wants to be long-term.

About the founder

Dr. Alisha Menon, Founder and CEO of Aurelia Vitals, Inc., the company behind Phira, received her Ph.D. in Electrical Engineering and Computer Science from UC Berkeley, where she worked at the frontier of machine learning integrated with advanced wearable sensors. She is a National Science Foundation (NSF) Fellow, a UC Berkeley EECS Fellow, a Rice Biotech Launchpad Fellow, and has first-authored 9 peer-reviewed publications spanning physiological sensing, intelligent systems, and human-centered device design. Dr. Menon previously worked at CTRL-labs (acquired by Meta) and Apple, contributing to next-generation sensing technologies and seamless human-device interfaces.

"I wanted a tool that could tell me what my body was actually doing, and why. The information available to me was fragmented, retrospective, and never quite enough to act on. Phira is designed for insight into my own biology, in a way that fits my life."

The Company Journey

Built in the Texas Medical Center.

Grounded in science

We built the first version of Phira in early 2025, and from there, we started learning what the signals could actually tell us about the menstrual cycle. As we collected more data, we began seeing signals that pointed to underlying hormone patterns. That eventually grew into an IRB-approved pilot study, which wrapped in early 2026.

With support from the National Science Foundation, early backing from Rice University’s Liu Idea Lab for Innovation & Entrepreneurship as well as Rice Biotech Launchpad, and research funding with collaboration from Baylor College of Medicine, Phira is grounded in rigorous science and clinical collaboration. The company is operating from dedicated lab facilities within the Texas Medical Center, the largest medical center in the world.

Be part of what we're building.

We're at an early and exciting stage expanding our research, refining our platform, and building a community of women who believe the same thing we do: that women's health deserves better tools.
