This startup wants you to breathe easier, literally.
Atlanta-based Seesaw Health is out with their first product, the Egg, designed to give users an on-demand breathwork coach.
Users simply breathe into the Egg and play a quick, one-minute online game. With a combination of the physical Egg product and an app, users track their Heart Rate Variability (HRV) and respiration rate. The Egg’s biosensor measures a user’s frequency and rhythm and then guides them how to change their breathing.
This technique is important in helping people understand their body’s stress response.
“These are key indicators of the parasympathetic nervous system (PNS) activity. Rather than continuous monitoring, we find it more relevant to measure the PNS response to a controlled stimulus, specifically 0.1 Hz breathwork. Improving this neuro-vagal balance through breathwork directly enhances stress resilience, sleep quality, and overall well-being,” said co-founder Celine Vignal.
Building HealthTech In The Consumer Space
Vignal and her team worked on building out the hardware and software over the last three years. Its technology was studied and tested through independent studies at global research institutes like UC Davis, Trinity College Dublin, and Sorbonne University. The Egg is now available to buy online starting at $129.
Vignal said that the company landed on the name Seesaw Health because they are focused on building products that “help individuals find balance in their nervous system, much like a physical seesaw balances. Specifically, we help counteract the "downs" of the nervous system, which manifest as symptoms like stress, pain, anxiety, and chronic fatigue.”
In its early stages, Seesaw’s target customers are women (though men can just as easily use the technology) and has assembled a team of women’s health advisors.
Vignal holds degrees from ECG Business School and the Université de Tours in France and Davidson College in North Carolina. She moved to Atlanta two years ago from the West Coast, telling Hypepotamus that she has loved building in the city and calls the local tech startup community “vibrant and incredibly supportive.”
Last month, Vignal was a finalist for the 2025 Women in Technology (WIT) Awards.
