Consulting or support. State it clearly on the project page and make sure you have a correct license. You need be aware if the library choice in said enterprises is a must-have or nice-to-have. I wouldn’t bet on corp. manager freeing a budget for a non-critical library. Also, while handling tickets, you can politely explain the user the paid support or consulting if they need it ASAP or require more support. This will can get the manager’s attention more than just “let’s support this guy because we use it”. As a last resort, you could consider paywalling new features and improvements. Or basically creating paid downstream product with a support and implement changes to the upstream. Sounds awful but that’s basically what most open-source companies do to keep new products alive :)
