Looking for Solutions to Securely Transfer Large Corporate Funds

[JonDoe]

I am looking for practical solutions to transfer funds from companies I already have access to. These involve larger amounts that cannot simply be parked in small personal accounts. Unfortunately, I currently do not have business accounts (yet).
It’s important that these accounts are not newly created – I want to avoid the risk of frozen funds at all costs. I think you understand what I mean. Cryptocurrencies seem less suitable due to high barriers, but I’m open to being convinced otherwise if there are viable approaches.
If you have ideas on where to acquire established business accounts or know of any “offshore” solutions that could help in this context, feel free to let me know. I can guarantee that the payments will hold for at least five days.
