At Centenary Day, we believe longevity isn’t a lottery — it’s a design problem. Our mission is to make it possible for anyone, anywhere, to take control of their health and extend their lifespan through science-powered tools, personalized guidance, and a community committed to thriving beyond 100 years.
Centenary Day was born from a simple question:
If science already knows how to help us live longer and healthier, why is it so hard to put it into practice?
Our founder, Arnas Stučinskas, combined 20 years of technology leadership with advanced systems biology research to answer this challenge. What started as a personal quest became a platform to democratize longevity—turning complex science into accessible tools that fit real life.
We’ve built Centenary Day to be your ultimate health optimization toolkit, enabling you to sustain your health today so you’re ready to benefit from tomorrow’s breakthroughs in life extension.
