My company EventVue failed. We tried to sell the code, but didn't get any serious offers. We'd raised 500k in funding so any money we gained from a sale would have gone straight to repaying our investors. I would have loved to have been able to do that just for the long-term goodwill, but financially I didn't have any incentive to work on finding a buyer. The chances of us selling for greater than 500k after the team left quickly approached zero. Good startup founders are usually quickly picked up by other companies or launch into another gig of their own. For me, it was a hard decision to pull the plug on EventVue, but once I did, I wanted to move on as quickly as possible. Wrapping up the last pieces of EventVue was painful enough.
The code still lives on my laptop and I reference pieces from time to time. I would have open-sourced it, but it included a lot of expectations about how the infrastructure was set up and would have taken a ton of time to generalize or properly document. The demand obviously wasn't there or else we wouldn't have gone out of business.
So there she lies. ~100,000 lines of code and 3 years of my life. May she RIP.
