Yves Guillemot

Who Yves Guillemot is

Yves Guillemot is a co-founder of Ubisoft and one of the five Guillemot brothers who started the company. Ubisoft's leadership page lists him as Co-Founder and Chief Executive Officer, and the biography document the company publishes for him gives his titles as Director, Chairman and Chief Executive Officer. He signs the messages the company carries on its news site, and its investor releases attribute their commentary to him.

The company's notice of meeting brochure for the general meeting of 30 September 2026 records his age as 65 and his nationality as French, in a table dated 20 May 2026. The same table gives the start of his first term as a director as 28 February 1988, a current term ending in 2028, and 38 years of presence on the board.

How did the Guillemot brothers start Ubisoft?

Ubisoft's biography document for him states that he and his four brothers founded the company in 1986, after he had left business school, and that they entered the video game industry while it was still forming. The document says the brothers understood early that creating original content in house and developing proprietary brands would be key to Ubisoft's long-term success.

The same document says his brothers appointed him Chairman, and that he established the company's strategy of using new technologies or changes in habits to innovate, create brands and capture market share. It states that he has supported Ubisoft's growth for more than 35 years and that the company followed a policy of organic growth with a focus on in-house talent.

What roles does Ubisoft's own record list for him?

The leadership page on Ubisoft's corporate site lists him among the company's officers as Co-Founder and Chief Executive Officer, and carries no publication date. The biography document describes him as Director, Chairman and Chief Executive Officer and states that the Chairman role came from his brothers. Neither of these pages records the year in which he took up either title.

The biography document also records awards: it says Ernst & Young named him Entrepreneur of the Year in 2009 and 2018, that Glassdoor elected him one of the Top 2 most esteemed CEOs in France in 2018, and that he received a Prize of Honor at the Pegase awards, the French academy of video game arts and technique, in March 2020.
