Kaigo Health (YC F25) just raised $500,000 from Y Combinator to build the future of preventive healthcare 🚀
Most people see me today as “the fit guy”. But at 15, I was overweight, dealing with chronic back pain, and couldn’t do a single push-up.
Preventive health became my turning point. I immersed myself in health science and embraced the quantified-self movement, transforming from chronic pain to benching 360+ lbs, surpassing Germany’s national records.
The bigger lesson was clear: health is preventive, not reactive. Continuous, not discrete.
We can’t reduce it to a yearly checkup or a single data point - it’s built by showing up every day, guided by continuous signals and small actions that compound over time.
Years forward, curiosity led me to take classes at the Stanford Prevention Research Center, where I saw how much science existed - and how little of it ever reached people’s lives.
That truth hit hardest when I landed back in Germany and missed saying goodbye to my grandmother by just 30 minutes.
Her health had looked fine from the outside - but her decline happened quietly, shaped by years of lifestyle patterns and a system built for sick care rather than health care.
It left me asking: how could we have prevented this?
Two months ago, I left Germany to find an answer. Together with my brilliant co-founders Peter Chien and Kazuki Shin, we founded Kaigo Health (YC F25) to build a world where healthcare is continuous, proactive, and always on - where hospitals are neither the beginning nor the end of care.
👉 Today, we’re launching AI nurses that listen, detect early warning signs, and ensure every elderly patient has a friendly voice advocating for their health at all times.
And this is just the beginning. We assembled a world-class team from Neuralink, NVIDIA, and Stanford University to build out a larger vision.
If you’re building or investing in the future of healthcare, let’s connect - we’re moving fast and ready to scale this mission.
