BitList labels SolCard and Stealths as KYC-free. However, while Stealths indeed unequivocally provides that they do not require any kind of verification from their customers, SolCard does.
~snip~
Stealths offers virtual cards without KYC from their side, but some of the card providers may in exceptional cases ask for KYC from the client. However, it is one of the services that has been functioning for almost 1 year (at least as far as the forum is concerned) and no one (so far) has had a complaint about it.
