Reminder for VC backed startups regarding revenue, profitability and growth:
Typically, the goal is not to build a profitable business. The goal is to build something people/companies love whereby you understand the cost of growth (unit economics, revenue short fall etc) - and then fueling that growth as fast as you can with venture capital.
Over time, economies of scale, network effects and new revenue streams should make up the difference and blast you through to profitability at scale - or someone buys your big, growing and unique user-base for lots of $$
