From the homepage it took me 7 clicks to drill-down into information about a specific compute service and see pricing, and it leads to their generic contact form page: https://www.stackit.de/en/contact
They're really missing that these big digital movements / transformations typically start out as a single person investigating / fiddling around with the service on some trial account or with a $10 provisioning spend as part of a few hours long Jira ticket on a Friday afternoon.
By inserting humans in the middle of this process (and the delay and back-and-forth which is incurred from having to formally give all that company information and implementation planning information and have it vetted) they're going to turn off a really significant number of potentially lucrative clients who will go elsewhere because they don't have to mess around with humans until they're sure of what they want.
