June 2014: Our story begins at Tinder. Tinder cofounder, Whitney Wolfe, leaves the company and sues for sexual harassment. She published her text conversations with fellow cofounder Justin Mateen as evidence.

September 2014: The sexual harassment lawsuit is settled, with Wolfe netting just over $1 million from the settlement.

November 2014: Wolfe joins up with two other early Tinder employees, former Tinder cofounder, Chris Gulczynski, and former Tinder VP of Design, Sarah Mick, to launch a direct competitor to Tinder called Bumble.

December 2014: Bumble officially launches. The original design of the app bore a striking resemblance to Tinder’s swipe left/right system. But with Bumble, women hold all the power. Men can’t send the first message and instead, women have to initiate a conversation with their matches within a 24-hour period. This idea behind Bumble gives women a power play, and attempts to change the mobile dating game. The only control a man has within the app is the ability to extend one match (per day) for an extra 24 hours, and hope his chosen lady will throw him a bone.

February 2015: Bumble introduced photo-messaging, which was one of the first times that a mobile dating app allowed users to send each other direct photo messages.

March 2015: The app introduced a backtrack feature that allowed users to take back accidental left swipes, which is very similar to the rewind feature available in Tinder Plus.

August 2015: Bumble boasts over 5 million conversations started by women, over 1 billion swipes, and an insane 15 percent week-over-week growth. In August, the app also implemented an algorithm called VIBee, a verification system that rewards good user behavior and engagement. Certified users can then enter a special mode of swiping where they’re matched up with fellow VIBees. #Goals.
