I find Posthog interesting because it launched around the same time (2020ish) as Stan.Store.

Not Posthog is a technically much more challenging product and is more geared towards developers and yet in terms of ARR it is at 10 million whereas Stan.Store which is basically link in bio + a very basic store is doing 25 million ARR.

Goes to show, selling to developers is really hard. Hopefully Posthog makes it in the long term, but graphing time spent vs returns, something like Stan.Store will make the founder + investors a lot more money in a shorter time period.
