Born in the 1990s and taken over by Eric Jemin in 2003, Groupe DAO provides mechanical design-office services, mechanical engineering and building modeling for companies in France and North America. Its more than 100 employees work through regional entities from Angers to Québec, supplying project designers either on client sites or remotely. The group remains family-led, with Eric’s son David Jemin taking over in 2023, and has built its network around local access and opportunities for younger technical talent.
