🌱 The project

About us

Life expectancy is around 85 in Western countries; However "Healthy Life expectancy" (without disability) is only 65. Our seniors live over 20% of their lives with with bad health and limitations, many of which can be avoided or delayed with the proper guidance and by improving lifestyle and behaviors. We set up the mission to increase people's Healthy Life Expectancy for millions to avoid dependency.

We are building an AI Longevity Coach for seniors to increase their Healthspan from home. In particular, we start with Frailty. Frailty is a silent epidemic that affects over 50% of the senior population. Frailty leads to loss of equilibrium, then a bad falling, then long rehab, reduced muscle, sacorpenia, en finally dependance, with the massive impact to their families and society. Frailty can be reverted with proper evaluation, exercise plans, motivation and monitoring. This has been proven in the offline world with the methodology of world-renowned longevity professor Viña. He has joined our company to create a longevity methodology online. Frailty is our first pillar in our Longevity Plan.

Founder team has decades of combined experience working with seniors, longevity, building and scaling tech products and starting companies. We are building a world-class team, with a small and strong pack of core members with the experience and motivation to make the project to fulfill it's vision and ambition. You will join as one of the first, and will use the opportunity to shape what will come after for you and your fellow peers. We believe in our purpose. We are here for the long run.

We have raised venture capital from some top VCs, and have a few thousand users to get things moving.
