Renardo Tech grew from the meeting of Jessie Coiffard and Teerapong Dabreteau, two builders convinced that imaging sensors can show industrial inspectors what they cannot yet see. The company was cofounded in Nantes and has worked with academic research labs from day one.

For decades, industrial inspection has relied on point-by-point measurements and complex analyses. We are bringing the field into the imaging era: see a defect across an entire area, in real time, without direct contact. The shift mirrors the move from thermometer to thermal camera.

The global non-destructive industrial inspection market is worth 16 billion dollars and grows by 10% each year. Every critical defect missed can cost millions of euros in losses. Our ambition is to become the European reference for electromagnetic imaging in industrial maintenance.

Our roadmap rests on three building blocks: 2D imaging sensors for electric and magnetic fields, and magnetic excitation sources. The first product is the electrical-activity imaging sensor, due in June 2026. The eddy-current imaging sensor follows by the end of 2027.
