No problem, really. I didn't take it negatively at all, I understand that's a lot of time. The best thing we could do to test the product was to find a few users (paying users) and do some mechanical turk work. When the testing period ended they were willing to pay double to continue using the product, but our costs were growing by 10x. They knew upfront it was just a temporary service, we promised them 6 months of free service when we finally finish it. To mitigate the consequences of our failure, none of us quit our other company (we are working there part time) and we didn't get into debt. We hired some very bright guys to help us, we tried getting things faster by hiring more people, it didn't work out very well.
