There's never really just one point of failure. There is maybe a so called turning point, one mistake that is then daisy chained with other mistakes. Soon enough the compounded mistakes lead to an overall failure. You have passion, dedication, and more. The founders there weren't right, and now you've learned something pretty damn valuable. Time to move on and start something new, don't let one failure ever stop you.
