They probably have already received the cease and desist letter from the 'other Ripple' (https://ripple.com/)

....seriously what were they thinking?

Seems like a dangerous time to launch an app named Ripple.

I think LinkedIn is probably prime for being disrupted by something, but I feel like the "swipe right or left" interface has been monopolized by low effort activities (shopping, tinder, etc) and it doesn't feel very professional. I wonder if the app will be able to succeed despite this.

Almost exactly like the defunct Weave: https://weave.in/

Definitely agree that there is an unmet need and huge market here. Best of luck to them.
