IIRC Revolut Business is available in Estonia, so probably no need to travel.

Please do not rely exclusively on one of the new fintech "banks" as your only bank. It is a recipe for disaster.

Revolut for business closed my account with very short warning and fucked up sending me my remaining balance.

Lukcy for me, previous issues had meant I was loyal to the concept of having at least two banks at any given time, because one might crash/throw you out etc, so it didn't cause me too many problems.

Now I have a boring, expensive local bank which is stuck in the 80s (but presumably safe) and Transferwise for all the online stuff.

It's not that I have a lot of trust in the challenger banks, more of the opposite -- I don't trust the old banks much more than I would trust Revolut. It's very easy to exit their (broken) state machine, e.g. if you use the eID card for 2FA login and it expires. The thing with Revolut, Transferwise, etc is they don't rely on having physical offices.

I agree that it's always a good idea to have multiple accounts.

Could you share what was their reason for doing this? Any non-standard type of business or account activity?

There is very little to tell...

Pure software development/consulting business for other business clients in EU countries. As clean as it comes, I think.

I was never told what the problem was. This is standard operating procedure for banks, I am told. So I still have absolutely no clue what the problem was.
