This is very interesting. If ownership percentages at Series A are trending down, and investor time & emotional investment per company is trending down as a result, but having outside accountability predicts success, then I wonder how the best companies will replicate outside accountability.
Put another way: How could you hack a replacement for a board meeting?
I'm a funded entrepreneur without a board. I've tried nominating advisors and/or very-helpful angels as our "pseudo-board" and meeting monthly. This didn't help very much: There's something about having a lot of skin in the game that makes board members really prepare, take it seriously, and summon courage to have hard conversations with CEOs when things aren't working.
The one thing that worked pretty well was bolting a whiteboard over the desk area with this month's single goal (a revenue number, natch) and value so far. I don't have any board experience to compare it to, but it certainly keeps us focused.
Anyone else have ideas that have worked, or might work?
