Are you planning to make a disclosure regarding that statement, such as being co-founders with Quentin Adam, the founder of Clever Cloud, in other projects?
Stuff like this should always be disclosed. Something like "My co-founder / friend built ..." would be totally fine, but this comment looks like it intentionally obscures the connection. Not a good look.
You live in the same city. You founded a project with him. It's not like you have submitted patches to Linux from different parts of the world, without ever seeing each other.
I don't want to sound like I have something personal (I didn't even know your names until yesterday) but your assumption that the readers here on HN have no clue makes me sick.
If you know each other, that should be disclosed. I have no qualms about recommending a friend's startup, given that the friendship is disclosed.
I have moved my side project (single server handling ~3 requests/s) from Heroku to Clever Cloud about 3 years ago and they work very reliably for me.
The truth is, on this scale Heroku worked well too. The reason to move for me was that they are an EU company so there is less questions from my clients about GDPR compliance.
I'd say the UI is quite old-school and I am missing good built-in metrics. There are some paid add-ons providing metrics but I'd really want to have it built-in.
