Holy hell. My MVP backbone works and I have the data to prove it…. Now what? (I will not promote)

The app is a novel (ie. complicated) approach to an existing market and I can finally prove that it will work. If it works we can instantly compete with established players. Well, After 6+ months of building I can prove that it will work (hot f***ing dog!). So now what? At my rate the MVP is 8+ months out. The mountain of work is…large. I’m a solo developer with a marketing focused partner, we have a few other founders but they aren’t business or technical oriented. We have a Delaware LLC, marketing has a plan for attracting and landing and is working on it. But I feel like I’m missing the next step everyone else could be working on as I put in 4+ hours a night into the MVP…. They are just kinda sitting there twiddling their thumbs. Do I have enough to start courting incubators or VCs? Should they hunt grants or try and find more technical founders? How fully formed of MVP do I need? I will not promote
