Seems like they have some decent companies using them too.
I don't know if we want to go that direction though. Plus I wasn't even sure who is actually self hosting these days. Kind of reminds me of the Silicon Valley show with the "box" in the data center dilemma.
About every company who don't outsource everything + every company that adheres to strict privacy rules + every company that is forbidden to share user data because of regulations + every company that is beyond what free GA has to offer.
That's like a shit tons of companies, a lot of which are established and have money. Just sayin'
The bigger the data the more self-hosting will make sense for you, but the less for your customers.
This works for snowplow because they sell services, which only really works for bigger companies who have the resources to self-host and to pay the services fees.
I don't use them, but they are building enterprise-grade self-hosting.
