It was called called "Startup Engineering" [1]. This course doesn't exist on coursera anymore, there's a similar syllabus on Stanford's website [2]. The project was something about building a small web app with node.js and accepting enabling donations via bitcoin payment.

I was trying to find the course in the archive.org's backup of coursera [3] but it doesn't appear to be searchable.
