Hi, congrats on the launch!
Firstly, it doesn’t seem to work for me and my wife - we hold the phones together but clicking start does nothing (and we’ve accepted Bluetooth etc).
Secondly, I wonder if you’ll have a massive chicken and egg issue with the physical feature. I get it’s the main feature but could you overcome it somehow initially while still maintaining your long term “gimmick”? Like could you allow people to connect with the first X friends (5? 10? 20? Whatever that can get virality and flywheel going) or connect with as many as you want virtually for the first X months etc. You could even have the contacts fade away slowly if they don’t get verified in person etc. You might want to model out different strategies (and be extremely conservative) otherwise you’ll be relying on lottery-level luck. Good luck anyway though :)
