Now if you were to replace religion with life, we might have something...
Most fail and fail quickly.
Often the failures come from the same things that kill startups. Focus on the wrong things. Not finding its market. Not serving its market. Burning through cash before reaching positive cash flow. Inability to adjust. Inability to scale. etc.
So religion is really another type of institution, like business or government. And, perhaps, more religions would be sustainable if they adopted lean startup practices.
