François Jacquemart

Co-founder of Amperio

François Jacquemart is a co-founder of Amperio, the Belgian app for electricians. He leads the commercial launch, the website content and the relationship with users.

Before Amperio, he ran Bsit, the childcare app with one million registered users, after five years in charge of its marketing, data analysis and product. In 2026 he built, for Vertuoza, management software for construction companies, a prospecting system aimed at Belgian building firms. He holds a master’s degree in management science (entrepreneurship) from the Solvay Brussels School.

The articles he signs are written from the official text of Book 1 of the RGIE published by the FPS Economy, every rule cited with its section, and dated at each revision. They inform; they replace neither the regulation nor the opinion of the accredited inspection body.
