There is absolutely a startup support industry. I am wary of using tools that seem to cater to startups only or that are interops between other startups, because I see the whole industry as brittle. Robust in aggregate, but individual services come and go daily.

I want longevity in my tooling, and I personally feel it's irresponsible to put your product into the hands of thirty companies who are all on the same growth or die cycle.
