THE MOTLEY FOOL - July 24 - The latest service to join Match is Hinge, a site that once billed itself as the "anti-Tinder" because it focuses on relationships instead of hookups. The purchase leaves Bumble as the only major dating app not owned by Match, and the two are currently suing each other. Match has acquired dozens of services over the past nine years and in the past three years spent $610M acquiring different brands, about equal to its cumulative operating earnings for the same period. While none of the deals have seemed to have gone like a bad date, the rise in Match's cost of revenues has outpaced its revenue increases due to acquisitions like POF and Pairs. Last year, revenue from North America, which contributes 56% of Match's total, grew 9% as a result of more people signing up for Tinder. Yet North America ARPU was flat. The deal for Hinge gives Match a 51% stake with the right to purchase the rest of Hinge within the next year. Though Hinge doesn't disclose the number of users it has, undoubtedly individuals using dating apps have accounts at multiple sites, so Match is paying for members it likely already owns. Match's total subscribers hit 7.43M in the Q1, up 26% YOY, and some of them have to be Hinge members, too. Making another acquisition might put another dating app into Match's diverse collection, but it doesn't really do anything to bolster what is making money for it, namely Tinder.
