We are just about starting out with my company and I've literally just made our live analytics public at https://analytics.moonka.space - it's literally everything we see.
We are using Plausible.io (kudos to them!), a privacy-first analytics platform that provides just enough data without abusing our users' data. This way, we don't even have to show a cookie notice.
I'm planning to open up our financial details as well as soon as we have enough transactions so that our clients can't be identified based on our data.
*edit: grammar
