I was referring to Silicon valley salaries, obviously you would need ~ 50-100 people or such. At current scale of Uber, if they charged just a penny (instead of the 20-30% they currently do) They would make 16 million dollars which could pay 100 people an average of 100K per year, they could spend $4M on infrastructure and still make $2M in profit despite being not much more than a payment processor and app provider (like square or shopify) They bill more than 200X that on average.
