The deal will run for three seasons, from the 2021-22 campaign that kicks off this weekend, until 2023-24.
As a partner of the club, Parimatch Tech will gain access to a rage of Chelsea’s digital, social and logistical assets to create mutual branding opportunities.
“Chelsea’s unique style, determination and charisma resonate perfectly with Parimatch’s passion for sport and ambition,” Parimatch Tech co-chief executive Roman Syrotian said.
Chelsea chief executive Guy Laurence added: “Last year was immensely successful for Parimatch as they expanded and opened new markets, while launching several game-changing projects. Chelsea also showed its excellence, becoming European champions for the second time in our history.
“We are excited and proud of this partnership and the opportunities it brings.”
The deal comes after Parimatch Tech last month rebranded from Parimatch in a move designed to increase focus on its B2B marketing and technology solutions.
The operator said the rebrand highlights its “technological transformation”, from its formation as a retail bookmaker in Ukraine in 1994 to its growth in the online sector. This included a return to its home market earlier this year, as Parimatch secured the first sports betting licence when Ukraine re-legalised various forms of gambling.
