Firstly - impressive work bva - I’m curious about your microservice, sounds interesting for verification.
The legal entity name is “Vast.ai Inc.”, a Delaware c-corp also registered in the state of California (and you can look it up on either site to get entity numbers, etc). That company name shows up on any simple invoice from the billing page (and is also on the TOS). Being a small US c-corp we don’t have a VAT number. There is a phone number on the site, but it’s not prominent as we prefer support goes through crisp (online chat) or email.
Stripe is our merchant account that we use for all credit card processing. We also naturally have a US business bank account.
