Dr. Julia Grosse is the founder of The Cyclical CEO™, where she helps high-performing women and business teams achieve sustainable growth by syncing strategy with biology. With a background in biology and years of field research—including leadership experience during the largest polar science mission of our time, the MOSAiC Arctic Expedition—Julia bridges performance science, female leadership, and business systems.
Her career began as a scientist, but burnout and firsthand leadership experience in extreme environments revealed a missing piece: productivity and decision-making don’t operate on a 24-hour schedule, especially for women. This insight led her to pioneer rhythm-based business frameworks that combine hormonal intelligence, cognitive science, and modern productivity models.
Through her signature programs—like the Business Rhythm Blueprint and the S.C.A.L.E. Method—Julia has equipped leaders, entrepreneurs, and HR professionals across Europe to harness their natural cycles for better focus, communication, and wellbeing. Her work has been featured in New Me Event Series, Leaders Perception Magazine, and the Womanship “Behind the Bio” podcast.
Julia’s practical, evidence-based approach activates audiences: her sessions don’t just inform—they inspire action and lasting results. Whether you’re scaling a business, building resilient teams, or seeking new models for sustainable performance, Julia brings a fresh science-backed perspective that redefines leadership for the future of work.

Leading in Rhythm: How Women Make Better Decisions with Biological Intelligence
Most productivity systems were built on data from male bodies. Not by malice. By default. And when better data became available, nobody went back to redesign the system.
This talk is about what that missing data actually shows.
Women run on a 28-day cycle, not a 24-hour one. Estrogen rises 8-fold. Progesterone rises 80-fold. The brain runs on a completely different hormonal environment every week of the month. That variation was removed from performance research because it was too complicated to correct for. Then the findings were applied to women anyway.
In 30 minutes: the research that finally looked, the 4 CEO Types mapped to the cycle, why the gender gap in negotiation is partly a timing problem, and what leadership looks like when it accounts for how women actually work.
For HR leads, people managers, L&D professionals, and women in leadership.
And for any woman who has ever called herself inconsistent.
