It's worth thinking about the team in advance, especially to understand what things you do well and where you need complementary talents. Good teams also work through the problems that are inevitable in new products. There's a great speech by Ed Catmull that makes this point well. (https://www.youtube.com/watch?v=k2h2lvhzMDc)

Of course this is useless advice if you are doing a one-person business. :)
