As they look to expand their international offering, and go head to head against Airbnb, Europe’s 9flats has acquired iStopOver, a global short-term rentals provider. Financial terms were not disclosed. This will give 9flats a stronger Canadian footprint and specifically an office in Toronto. iStopOver’s early investors include JLA Ventures, GrowthWorks Commercialization Fund Ltd., Brightspark, and other investors.
