The sports betting supplier has been powering the LeoVegas sportsbook since 2016, although the new agreement will see a greater number of brands switch to the Kambi platform.
Through Kambi's software, LeoVegas has run sports betting in the UK, Sweden, Denmark and Spain.
Kristian Nylén, Kambi CEO, said: “We are proud to have agreed this partnership extension with LeoVegas, and that Kambi will now provide its sports betting services to the other brands in the LeoVegas group."
Mattias Wedar, CPO & CTO at LeoVegas, said: “We are pleased to continue our sports betting journey with Kambi, a partnership which has brought about real success as we continue to deliver on our sports betting ambitions."
