Building decision intelligence tools that let governments see the consequences of a policy before they enact it.
About
Marcel Bartumeu Ramentol is an entrepreneur, technologist, and builder. He works across companies, physical products, software, and decision-making systems for governments. What ties it all together is a fascination with how people and institutions make decisions, and how better tools can change the outcomes.
Originally from Andorra, he founded his first company, Mevot, an electric longboard startup, at 15 and grew it to six figures in annual revenue before exiting at 19. Along the way he built electric cars, 3D-printed hardware, and games from scratch. Today he is completing a BSBA at Babson College alongside a Certificate in Engineering at Olin College, and serves as President of eTower, Babson's entrepreneurial residential community.
His current focus is decision intelligence. As a researcher in MIT Media Lab's City Science group, he is building Spectre, a platform that lets governments simulate the consequences of a policy before enacting it, with a live deployment modeling his home country of Andorra.
Before building companies, he competed as an elite alpine skier for Andorra's national team until 18, and that discipline still shapes how he works. He speaks five languages and cares most about building tools that help people make better decisions at scale.
Story

Age 10
Helped develop TerMITes, a platform for an MIT research group to deploy sensors in school classrooms and better understand how kids interacted with their environment.

Age 12
Bought his first 3D printer and started making physical projects, including a climbing device that used electromagnets, chasing a childhood dream of becoming Spider-Man.

Founded age 15 · Exited age 19
03
A sensor platform built for an MIT research group to study how children interact with their classroom environment.
Age 10
04
An independent product-creation studio, including backend engineering for an apparel brand doing seven figures in ARR.
Age 19
A first-author paper introducing a transparent, data-grounded framework that projects four national development pathways for Andorra to 2049. It derives population from GDP growth to give governments an auditable decision-support tool.
Submitted · Urban Science (2026)
A first-author paper on a household-grounded, network-first pipeline that generates 90,000 behaviorally grounded synthetic agents of Andorra. It forms the behavioral layer of the scenario engine, built with LLMs and knowledge graphs.
