François Mainguy worked at R/D Tech from 1995 to 1998, as their first applied physics technician working with phased array and EMAT ultrasound technologies. He then left to eventually found HARFANG Microtechniques in August 2001. He introduced the first portable ultrasound phased array system for nondestructive evaluation, in June 2002. In 2005, he sold his company to The Sonatest Group (Milton Keynes, UK), where he worked for three years.

In June 2008, he founded UNGAVA in Québec City, to offer design, engineering, prototyping and OEM production for customers. UNGAVA specializes in value-added devices based on complex electronics, embedded software, digital signal processing, visualization software, and mobility. In 2012, he introduced PRAGMA as a division of UNGAVA.

Mr. Mainguy has technical training in applied physics engineering (Cégep La Pocatière), an Electrical Engineering degree from l’École de Technologie Supérieure (Montréal) and a specialization in microelectronics at l’École d’Ingénieurs du Canton de Neuchâtel (Switzerland).


Mike Reilly was previously Group Managing Director of Sonatest PLC from 1989 to 2009, during which time the group grew from a $2m to $25m business.
