How hard would it be to build a api as a service company using racket?

hey, I have always gotten excited about starting a company with lisp or haskell.

Was wondering if it would be a good decision choosing racket if I happen to start something. thanks

Do you mean a service something like the AWS/azure/google speech recognition API's where users sign up for an account and then get billed for usage of the services?

What I have in mind is something like a Chat API and SDK that allows programmers to integrate chat functionality into their apps. So, essentially Stripe but for chat or for fraud detection or something else.
