I signed up for Stripe Atlas which included an LLC, bank account, and an EIN number. I was also able to partner with Stripe Atlas to join AWS Amplify to receive some AWS credits to keep my costs down for a while. I was planning to sign up for Stripe anyway, I still needed a business account and to get my EIN, and the Atlas program made it very easy to set everything up. It was a nice bonus to receive the AWS credits from the Amplify program. Looking forward to next steps!
