FORWARD.COM - Oct 7 - David Yarus, 30, and his three co-founders launched JSwipe during Passover 2014 to capitalize on the extra downtime people had while home for the holiday. It seems to have worked. The app boasts 800K users worldwide. JSwipe is now officially part of Spark Networks. While prior to the merger Yarus called JDate an "outdated organization" with "an outdated business model," he and his team seem to have fully embraced the challenge of bringing it up to speed.
