Weaving and Bobbing
The real art of the start, to steal a phrase from Guy Kawasaki, is the "weave and bob".
Dick Costolo of Feedburner says, "it's about realizing you are going down a dead end before the other guys do".
Matt Blumberg of ReturnPath has a post up on his personal weblog about the original ReturnPath business plan, email change of address.
Matt and his team weaved and bobbed a lot over the past five years and have built a business that includes a lot more than ECOA.
That's how you have to do it. I cannot think of many startups that are still executing their original business plan.
