A personal reason
Why I built LifeTrajectory
I’m Andreas Holzhäuser, founder of LifeTrajectory, a self-taught product builder and father of four. One question is deeply personal to me: What can I do today to remain physically capable, mentally alert, and present for my family for as long as possible?
I hope to live long enough to see my great-grandchildren grow up. That ambition led me to build LifeTrajectory: not as a medical promise, but as a transparent educational tool that turns longevity research into understandable next steps.
