> We were building a complex and big management system Sounds like long sales cycles + probably a longish period between "sale" and "integration done, workers trained, in production" (which may be the point when the cash starts flowing...). > My idea is to finish the MVP and giving the project the opportunity to find another client without expending more money. I don't know the specific market you are in and the technical ability of the persons you are trying to sell to. It may be that a finished MVP vs. a 60% done MVP doesn't significantly improve the chance of a sale. It may be that for the sales process, slides-only or a 5 min click demo are enough to convince the client of your technical ability and the discussion will move on to other topics. Apparently this has worked before, and the owner may be looking to replicate that before investing further time into building the MVP. Sales is tough, really tough, and may be the far bigger problem for the startup. A finished MVP doesn't necessarily make this easier, sadly.
