Strip Tipz

Their pitch reads like a presentation on Shark Tank.
Maybe it will be.
Stay tuned.

*a way to give dancers money for nothing.

Won't be the first time. Perhaps you should have said "another way".

"watch their cash tally increase while they dance on the screen of the mobile device"

They must have very small feet. Those screens aren't that large.

Won't work (or won't be allowed) in a well-managed club, unless they create a club-branded version for the club to deploy to it's hired or contracted dancers. That means club management will be (must be) able to monitor tips by dancer and can then do accurate tracking for reporting, taxes and dancer performance needs. Plus, most clubs I know have rules about PL's not using a phone on the floor to prevent unauthorized pics of naked dancers.

So, it's an interesting idea and it's moving the industry forward to the inevitable death of cash. But they need to work out the use cases in much more detail. And they should be looking for a partner brand (Deja VU or Rhino?) to help develop it.

Great... Another thing to keep her focused on her phone.
