No sarcasm . . . How is it not possible to survive for a year for 50k? . . . We do not need an office or need to hire any employees - we just need some hustling cash! . . . where are you guys from?
This makes the very poor assumption that the only reason you raise a round from an angel is to hire people. A small business can, and should, be able to do quite a bit with $50,000.
