This is a pretty cool example of how important it was to change business model (or at least be sensitive to being wrong about your initial expectation) and the uncanny serendipity of the valley.<p>One question, though: what kinds of factors go into the decisions behind accepting funding?<p>Really, to anyone -- what drives the decision to try raise that first five million vs. the next six million vs. the final ten?<p>This is to a good degree a n00b question because a) we can't know what it was spent on and b) I'm truthfully not that savvy behind the business decisions.<p>But if anyone has any insight (or insightful speculation), I'd like to hear what the differences behind these different rounds -- or even the decision to keep fundraising at all. Genuinely curious. Thanks!
