This is from years ago, but it was $4,900 for an SDK license for development and testing, and then the runtime licenses that you actually deploy are negotiable depending on pages/month, cores, languages, and other options. I think if you're just buying 1 runtime license they try to make it so it is around $5K so the total deal size is $10K. But they are negotiable. Maybe mention if you're a startup.
They also sold Recognition Server which has fewer options to integrate with programmatically (it was only 'hot folders' at the time), and I think only runs on Windows, but costs less.
And their mobile OCR which is lightweight, designed to run on smartphones, they worked out deals where they get a percentage of revenue.
