From 2007-2009, I was able to start an internet games company, run it as CEO, and then wind it down - with great collaborators and support from a broad range of folks. I wrote up the experience: A Story of GameLayers over the last eighteen months; adding tangible numbers and business documents. Hopefully this can be useful to other entrepreneurs!
Also I used it as an excuse to learn how to make an ebook: you can get A Story of GameLayers for the Kindle.
