...tiny bootstrap... platform... 3D spaces...

That quicksand has swallowed many a tiny startup.

The platform operates on Amazon EC. They did not take or try to take investment. And at least one person worked hard on it. This does not sound like failure. It sounds as if the product is either something that people do not want, or something that does not have commercial application in it's current state.

File this one under "find a job elsewhere and keep working on the project if it is worth working on".

I guess we're going to see a lot more of "why my start-up failed" posts these days.

here's a tip: quit calling yourself a CEO. you're a start-up entrepreneur. you're one person and if you're lucky you get to put together a team of 2 to 10 others that you work "with".
