Celine Vignal is the founder of Seesaw Health, a pioneering femtech company at the intersection of women’s health, biosensing, and behavioral therapies. With over two decades of global experience in sensor technology, marketing, and product innovation, her work bridges cutting-edge science with deeply personal insight.

After decades of navigating chronic migraines, Celine became driven to understand the link between nervous system regulation, cyclical inflammation, and chronic symptoms. This journey inspired Seesaw Health’s mission: to help women rebalance their nervous system and exit fight-or-flight mode (quickly, naturally, and effectively) through biofeedback-guided breathwork.

Under her leadership, Seesaw’s cross-disciplinary team is advancing patented digital biomarkers and real-time analytics that translate physiological signals into daily, actionable feedback. Using the company’s egg biosensor and companion breathwork app, women can now visualize their body’s stress and recovery cycles, gaining confidence and control over daily stressors, anxiety, flare-ups, and hormonal shifts that often disrupt focus, energy, and well-being.

A passionate advocate for data-informed women’s health, Celine is recognized for her ability to turn scientific complexity into intuitive, human-centered solutions. She was named to the Forbes Next 1000 list in 2021 and among the 50 Most Influential French in the U.S. Seesaw Health received Design Capital by Femovate in 2024 for its innovation in women’s wellness technology, and in 2025, Celine was honored as a finalist for the Women in Technology (WIT) Award for her leadership and impact in femtech innovation.
