I have a full time day-job and a family, so I could scrunch in some time whenever I could and successfully launched:
Oracle of Legends
Dotademy
Both were database websites for League of Legends and Dota 2 respectively, it was met with lots of love and kind words and usage. At it's peak I was looking at 25,000 daily users, with thousands voting on couterpicks for the champions/heroes. It was a "success" in my book.
Unfortunately around that time a website called Lolking was picked up by the Zam Gaming network (they own Wowhead, etc) and obviously that now had a team working on it as their job.
A team of devs working full time > a single dev working a couple of hours a week.
I learned a lot, had fun making it, but was sad when I ultimately pulled the plug. Who knows, I may revisit the websites and launch them for an international market. So far none of the big websites has localization and I know the latinamerican crowd is huge, so there's that. :)
All in all I spend 60$ for 4 months of hosting, nothing more.
I think that a failed startups feels quite similar to losing someone.
I still tear up when I talk about my previous company, but sitting it out enabled me to better handle it and now I'm very pumped up and working on my 3rd company.
Btw, I've blogged about it: http://www.eytanlevit.com/post/32192713706/sitting-shiva-on-...
I've been working on my startup for some time. I haven't been profitable (or funded) yet, but it's far from being a "failed" venture.
I've come to believe it's a "failed" venture once I reach a point where I've exhausted all of my ability and options. I haven't reached that point because I can just learn to code to build it. I was relying too much on finding technical cofounders because I didn't consider myself technical at the time.
Quite frankly, we were wantrepreneurs. Coming to terms with myself over that really helped in moving forward.
I've been building ever since and have someone willing to pay once it's done. Best thing is - I've realized that I enjoy building :).
