There is at least one company that does provide managed Lemmy services (which makes sense, since a lot of people might want to run their own instance, but don’t want to deal with security and updates and setting up x.509 certs and stuff).

Might be elest.io that I’m remembering.
Hey dear community, we just launched today our fully managed hosting of Lemmy
We offer to do Deployment / Security / SSL / DNS / SMTP / Monitoring / Alerts / Backups / Automated updates / Handle migrations / Fully automated but with Human support :)
We deploy each instance on a dedicated VM, and we provide full root access as well if you want to customize anything.
Pricing start at $10/month (billed hourly, no contract)
Looks like there’s another one at least:
Get Lemmy hosting that works for you
Only $11.25/mo. Risk-free with a 14-day money-back guarantee
Those are the ones that come up in a search. They’re probably hoping that the Threadiverse will grow; enough instances could make writing scripts and whatever pretty worthwhile.
