Lodovico Cortelazzo

Former member of the Italian national athletics team, competing in the 200m sprint at national and European level from 2015 to 2019. Those years gave me a perspective on performance that no degree can replicate — what the body signals at its limit, and where conventional wisdom simply does not hold up.

After competition I studied Sports Science and Engineering — two cultures that rarely talk to each other, which is exactly the problem I am trying to solve. Today I work as a rapid-prototype engineer in sport-tech: building sensors, embedded systems, and computer-vision tools to test ideas quickly, before serious resources are committed.

How I think

1

First principles before received wisdom

I go back to fundamentals every time — sport is full of practices that were never properly questioned, and engineering often adds complexity where simplicity would work better.

2

Validate with a prototype, not a slide deck

A working prototype in front of real athletes tells you more in one session than months of planning. The field is ruthless and honest. A spreadsheet is neither.

3

Connect domains that rarely talk to each other

The most interesting solutions sit at disciplinary boundaries. Cross-domain thinking consistently produces ideas that neither field would have reached on its own.

Mission

Combine sport and engineering to push performance forward.

Vision

Technology that makes training smarter, faster, and more efficient.
