Renardo is a start-up incubated at IMT Atlantique on the Nantes campus. Its mission: slash the time and cost of developing embedded electronic systems.

We met with Jessie Coiffard, engineer and co-founder of the company.

What is your project about?


Renardo is an early-stage start-up that aims to transform embedded electronics development—reducing time-to-market by a factor of 10. How? Through a custom-built development ecosystem shaped by more than a decade of industrial experience in high-demand sectors.

Today, designing an entirely new electronic product typically takes one to two years and requires hundreds of thousands of euros in investment. And after all that, the product may still fail to meet market expectations and constraints.

How is IMT’s incubator network helping you grow?


The IMT Atlantique incubator provides essential, day-to-day support that helps us rapidly build expertise across key areas—legal, accounting, business development, and more.

It also connects us to a strong, vibrant network, and opens doors to critical funding opportunities. Renardo, for example, was awarded an honor loan through the IMT Industrie & Énergie 4.0 fund—co-financed by the Mines-Télécom Foundation, Bpifrance, and Revital’Emploi.

Good to know: Honor loans—essential early-stage leverage


Offered through the Mines-Télécom Foundation, these loans are designed to secure the earliest—and often most difficult—phase of startup development. They complement regional funding mechanisms and help high-tech ventures like Renardo reach their first milestones.
