This happened a bit faster than I expected! Super exciting. You'll have an easier time selling this if you can attach it to accelerating revenue, vs. saving money or reducing risk (the core value primitives). It sounds like you're focused on building internal tools vs. building customer facing products - is this correct? Curious why, if so.
I'm also curious if you've automated maintenance and support - those will be big questions.
I would go out and talk to lots of people and do open-ended interviews. Ash Mauriya has a great article on this but there are tons of other great resources. Your goal is to figure out who cares the most about this and why.

I would normally say partnering with other software companies could be a strong play for you, but some might see you as competitive. I'm working on custom, on-demand enterprise integrations. We might make good partners :)
