When given an early stage investment a founder has to either use that money to pay for their life or invest it in their product. Making people devote themselves full time to an early idea means they need to spend the investment on salaries when it is usually way to early to do that.
I have heard angel investors in shock at a burn rate for a company that ran out of money out after 4 months, but the investment was only 50K and they were made to sign contracts that said they had to work exclusivly on the start up. The investors were mad, but then it seemed like they thought the founders were idiots for paying themselves salaries.
What gives?
