For decades, medical research has treated female biology as an outlier. The result? A healthcare system designed for men, and a silent epidemic of exhaustion for us. We are tired of guessing. We are ready to know.

Why we need you: We are building Serena—the first AI trained specifically on the female infradian rhythm. But an AI is only as smart as the data it learns from.

By joining the Validation Protocol, you aren't just testing an app. You are donating your data to a global trust. You are training the algorithm to recognize burnout, stress, and hormonal fatigue so that the millions of women who come after you won't have to fight so hard to be understood.

You are the pioneer. This is your legacy. serena-os.com/#/invite
