Aren't there a decent number of companies out there that take 1-5 million in funding and then 'bootstrap it' from there? This seems like a fairly reasonable middleground where you get some cash to help you get over the initial hump and form a team but still have to focus on building a sustainable business asap. Or are companies who seem to be on that trajectory avoided by seed investors even when the fundamentals look good?
