WALL STREET JOURNAL - Since Jan '19, App Annie data show U.S. users have spent 7.4M hours on dating apps a month on Android phones alone. Match Group and Bumble collectively boast ~$50B in fully diluted market value, but plenty of businesses are trying. Coffee Meets Bagel, which hits users with algorithmically curated matches every day at noon, has made ~130M matches since its launch in 2012. Hily, which works to make it easier to start conversations, has 22M users. Snack, which is focused on video-first dating, was the 10th most-downloaded dating app in the U.S. last month, according to App Annie. Some just need a larger platform to help them take off. Hinge, in which Match took a majority stake in 2018 before acquiring it in 2019, saw ~100K U.S. downloads in Jan '18. By Mar '21, it was closer to 600K. Berlin-based Spark Networks did $233M in revenue last year. And then there is eHarmony owner ParshipMeet, which is preparing for a 2022 IPO. In the Q2 it had €139M ($164.2M) in revenue.
