Your board (and VCs by extension) are not the only accountable 3rd-parties... I'd argue that they're not even the best accountable 3rd-parties because they're interests are not necessarily aligned with yours - VCs have limited partners to worry about.
Look no further than your customers for great 3rd-party accountability. If they love and use your product, they will pay you more money and recommend you to others. They should be the only thing that matters. In fact, by not having a board you have the luxury of only being accountable to them.
