Online notary

For the USA, I had used Jared Leiman, Chicago, IL who can be reached at jared@apostillellc.com - highly recommended.

I can vouch for Online Notartermine – notarity for EU use.
I’ve used it twice: once to set up an Austrian GmbH and once for a notarial acknowledgment of debt. Smooth process both times.

For EU I used Digidentity | Digital Identity Made Easy and namirial.com/en/- both automated signature verified that with an annual subscription between Eu 60 - Eu 80 (that was a while ago, numbers may have changed). They give you unlimited number of documents you sign by yourself once you are verified and they are deemed notarized meaning your signature is considered to be notarized but only for EU. I had used both a number of time mostly for signing a court documents to be used in Europe.

Once set up - and in both cases the respective onboarding processes leave much to be desired - it works very well, usually under 2 min per signature. Note that both provide a number of other services as well.

Digidentity is Dutch and Namirial is Italian based. Digidentity has customer service center in UK, Namirial in Italy so when calling Namirial one has to ask upfront for an English speaking agent unless one speaks Italian.

Hope this helps.

I stand corrected, the digital signature provided by the 2 abovenamed companies for my digital signature accepted by any EU state, in my specific case company-related documents and agreements. Thanks Johnny!
