Marcel Bartumeu Ramentol

Since 2025 I have worked with the City Science group at the MIT Media Lab. I simulate countries and cities, and build the tables and panels people use to test decisions on them.

ABOUT

I’m from Andorra.

I am first author of The Andorra Scenario Engine (Urban Science, 2026), published in August 2026.

I built a synthetic population of 90,000 people for my country, and the projection and Arduino control panel for a terrain table of Andorra.

Before that I built things: radio-controlled boats, cars and planes, an electric car at fourteen, and Mevot, an electric-longboard company I started at fifteen, grew to six figures in annual revenue and exited in 2025.

I study at Babson College and Olin College. I race alpine skiing for Andorra (FIS-licensed), raced two seasons for Babson’s men’s ski team, and was President of eTower, Babson’s founder community.

A 90,000-person synthetic Andorra

A synthetic Andorra of 90,000 people, tested against real surveys twice. Round 1 failed and Round 2 missed 12 of 24 items; both are reported here with their numbers.
