thanks for your answer Markstansbury, let say the co founder owns 35% of the company...in a typical start up, when do you allow them to vest the last portion? after a year, 2 years or when the company gets profitable?
my question here is, why would you be thinking about vc's at this point? Start small, look around familiar territory (family, friends, and fools...lol) for raising a small Angel round and also potential biz partnership.
one of the important things about start up is that you have a well documented starting to crawl before you walk is a well established tried and true method; My advice is use about 160 hrs for a good prototype. Use that to test if the idea has stickiness in the first place before you invest 1000 hrs.
