I want to offer my patent and consulting to a startup. How do I establish contact on eye level with one of their CEOs on LinkedIn or directly?

As a solopreneur/freelancer I still own a patent for location based display of personalized data on mobile devices from my previous (failed) startup which I also failed to monetize until now. I'd like to offer that patent and consulting to a startup that offers a broader approach to a problem I tackled before. What would be the best way to approach them?
