I picked those three companies because, far as I know, they are good. Here is what I can see missing:
Ramnode: no information about who runs it or how big a team they have. The legal name of the entity is correctly given, but not where it is registered not any registration number (most jurisdictions have them). The only contact address I could find was a PO Box number
BuyVM: TOS is in the name of Frantech, but there is no indication of what legal entity I am dealing with. No address, but whois gives a PO Box number in Canada, which is the only indication of what country they are based in. There are photos and a little info about Francisco and Aldryic on the about page, but gives the impression of a two man business, which is not consistent with the claim of 24/7 support. No contact address at all on the site, but there is what looks like real address in the whois.
SecureDragon: no address on the site, whois gives a PO Box number. Only two "founding members" are mentioned by name, so, again, it is not clear whether or not the small team IS the two of them.
None of them disclose financials. Bytemark actually links to their accounts on the companies house (the registrar of companies for England and Wales) which means you can see exactly what the filed. This may not be possible in other places, but posting a summary of your accounts and disclosing ownership is.
I also think BuyVM's humorous tema pages are a mistake. That sort of humours works well on other pages (I love the operating systems page) but I think it is out of place on the "about us" page and will lose you some customers.
