I've negotiated a bunch of license agreements over the last 15 years. Each one is different, obviously. You really need to get experienced counsel to help you articulate the deal and, thereafter, paper that deal. Using templates from other companies invariably ends badly, though it is unfortunately very common in the tech industry.

Licensing deals are all about leverage. Make sure both sides are getting something out of the relationship, both now and down the line. When it comes to platforms, you want to make sure some portion of the license is for use of the platform only, whether or not they make any money using it.

Happy to have a call to discuss in more detail.
