How should we approach a startup that's developed B2C tech that we want to leverage for our own B2B business?

Hi all,

Quick question - my startup is a music-tech company that's developing a new system from the ground up and coincidentally we found a company in Europe that already developed pretty much what we were imagining but for a different market. We're looking for a way to approach them with either a partnership strategy or some type of mutually beneficial relationship so they would allow us to use their B2C technology to grow our B2B business.

Does anyone have any recommendations on how to approach the company? I assume they'll want some type of cash/equity + % of sales-based compensation, but past that I have no idea what to expect.

Any suggestions are appreciated. Thank you!
