Whilst working on developing the app, I posted in 3 main coworking spaces in Canggu, Bali with a short intro text, and managed to get to 120 waiting list signups!
Whilst the product isn't ready, this a good test of demand AND a base to launch into in a matter of weeks (when the product is more developed). Canggu is also an ideal launch base due to the sheer density of digital nomads in a small area, making it perfect for a hyper-local social app.
