Sounds like the story of a young person who drank the VC cool-aid. The company should have been bootstrapped from the get-go... $25k/mo office, …doh.
Yep, easy to say as a greybeard and hindsight. But I remember Joel on Software articles on this subject circa 2000, so some information was out there.
Between the lines I feel a lot of self-punishment going on. Well, I'd love to have $10k+ of "failure" coming in every month, with the satisfaction of helping the little guy/gal no less.
Perhaps you'd consider selling to someone who believes in the mission and hates dark patterns? I don't have a lot of capital laying around, but some, and perhaps something else could be arranged?
