From what I've seen - a lot. You can lose a leading client (or cause huge bump on the road), your marketing plan can fall apart. It's about finishing stuff today, so tomorrow you can do more important strategical stuff. Start-up contrary to some of beliefs is not one big effort to reach the summit. It's a series of small wins (and loses) that accumulate. And you need to be accumulating them faster than your money runs out or competition takes the space, etc.
