Where are your former startup colleagues these days? If they are still working close to the startup field, it'd be good to talk with them, even if you you aren't looking for a direct referral. If you can get candid feedback from them it may help. Their gap analysis might be quite scary at first, but they can likely suggest ways for you close the gaps. And the gaps might only be at an appearance level. You've done the startup thing, I'm sure you can do it again if you persist.
