What to do with code once startup has failed?

I am an ex CTO in a failed startup. As any geek I still have feelings for the darn thing, and I have no clue what to do with the code...

Software in question is real time news analytic SAAS written in nodeJS and mongoDB.

Choose a good license and open source it on GitHub or somewhere else. If your company failed that doesn't mean somebody else can find your product interesting and use it. There's a possibility that your product can be improved and, who knows, eventually released again for commercial use (if the license permits it).

1. Try to sell it on flippa.

2. Failing that, put it on github, with a note that says "unsupported". (open source) It can help for future job interviews.

3. Delete from your local machine and move on with your life.
