(Render founder) We're still on public clouds because even if it doesn't help with margins, it helps us move faster on features our customers want. It's all one big prioritization problem (and lots of little ones too!).
I'm curious how significant a risk products like AWS Lightsail are to your business - it seems you are competing in the same market, but:
1. They have vastly different ongoing capital and cashflow requirements than you do.
2. They have all the leverage when it comes to the question of your continued operations on their cloud.
I'm also curious if they have already offered to just buy you out since you're clearly succeeding where they seem to just be treading water. (But not expecting you to answer this question. :) )
