“Ubisoft was deeply saddened to learn of the death of Claude Guillemot, co-founder of the group and chairman of Guillemot Corp, in an accident,” the statement said.
“Our thoughts are with his family and loved ones during this difficult time. No further statements will be made at this time,” it added.
Guillemot, 69, died on Friday in a plane crash in La Baule, a resort town on France’s Atlantic coast that was scheduled to host an air show this weekend, newspaper Ouest-France reported.
He was one of two people aboard the twin-engine Cessna 421 plane, the newspaper said. Both passengers died in the incident, Ouest-France said.
Guillemot helped transform Ubisoft from a mail-order software business into one of the world’s largest video game companies, before serving as chair of the family’s hardware arm Guillemot Corporation.
