FAST COMPANY - Feb 12 - Bumble went public on Thursday, and investors were very much interested in swiping right. The dating app, which soared in its first day of trading, is well-known for letting women make the first move. And in fact much of its success is due to this fundamental design decision. "The app is celebrating that women make the first move and men take a passenger seat. That sets us apart. And that's a design decision", said head of product design Lara Mendonça who joined the company in September 2019. The app's bright yellow color is meant to spark happiness. Mendonça's team has also introduced diverse illustrations that are meant to represent an audience of all backgrounds.
