POSTMEDIA NEWS - Aug 26 - Lumen, a dating app for the 50-plus crowd, is a runaway success. The app launched in the UK last fall by co-founders Antoine Argouges (ex-Bumble) and Charly Lester, and has 1.2M users worldwide. The app uses AI to ensure users are who they claim to be (promising 100% photo verification); the opening salvo has to be longer than 50 characters. "Working for Lumen has made me realize how 'old' people think 50 is, and how untrue that perception is," said Charly Lester. "When someone pictures a 50-year-old in their head, most of the time the image they are thinking of is a 70-year-old. We need to shake up these perceptions because they are wrong, and damaging."
