A tidbit of advice I got from a startup lawyer is that you want to provide value throughout the company's life. Apparently a lot of angels get screwed down the road (post VC) because they are no longer playing a big role. The founders, however, are often still playing an important role and get additional grants (especially if the founders are already fully vested after 3 or 4 years).
