Ask HN: How would you gracefully exit your startup?

Dear HN audience, I'm looking for ideas how to gracefully exit our startup, we can't maintain it much more. It's a browser based video tool for rapid video creation. The product never gone out of beta, it had a hundred testers, UI and technology is in pretty good shape, but we seriously lack business hustling / company building skills and at this stage I don't think it will get off the ground. I haven't met anybody who can take on the missing role in the last 3 years and I looked everywhere, no wonder, investors declined us, we also had no awesome work history and we live in Eastern Europe. I would consider an acquihiring a good exit, I feel no shame with that. Any feedback, ideas how to move further would be more than welcome.
