what were you big motivating milestones that kept you going? if anything caused you to almost give up, what was it and how did you overcome it?
...and then their trial ended and they paid.
Even though I'd written a full software system at that point, the app was still fairly hands-on, and it wasn't until then that it was fully obvious that someone would pay for just the software. In retrospect this is a pretty big thing that it would have made sense to test much earlier somehow.
I'm pretty optimistic by nature, and Complice has felt promising since the beginning. I think it probably helped that while I had a vision/goal (= become ramen-profitable by graduation) I didn't spend too much time fretting about it. I just focused on making incremental improvements to the system (eg UX).
And this in many ways is the philosophy of Complice itself: stay oriented towards the big picture, but focus on what you can do today.
