Unpark - Domain Activation Engine. I built this to solve my own problem of having 30+ parked domains. Instantly generates and deploys a simple AI website to any parked domain. For domain hoarders who aren't web developers.
I think about this quite often, as 2 of my kids were born in Ireland, but grew up elsewhere (Slavic country). I speak English with them, but so do some of my friends/neighbors with their kids. The other kids would seldom speak English though, while my kids seem to default to English somehow. Btw. they left Ireland when they were 2y and 9months old (now 9 and 7), never attended daycare there, were only exposed to English at grocery stores, doctors etc. My point is, the early exposure to the language seem to make huge difference. I'm sure it's a combination of other things too but I'd say it is definitely a strong factor.

I think the problem with these general-purpose PaaS on top of Cloud is exactly that they're general-purpose. You will run into limitations and issues as soon as you start doing things only 5-10% of their customers need, like for example running privileged docker containers in kubernetes or wanting to manage parts of your infra with terraform.
I'd much rather see tools helping me deploy one particular niche use case in Cloud really well.
BTW I'm trying to follow this mantra while building https://staticbot.dev
