Have you gotten any companies to agree to a royalty like this or is this just the initial monetization idea. I can see them paying 5 figures for a final report, but not a royalty on their bottom line sales.
As Mike said, currently we are going with a commission-based monetization strategy for the MVP, and based on feedback, it is subject to change.
Of course, we have many monetization strategies/features/mechanics we'd like to play with in the future, and they'll always be for the benefit of our users and the companies we work with.
