Even though it seems may seem obvious that your product should be desirable to one of those companies, it usually needs to fit very well into one of their long-term strategic roadmaps. Learning whether that's the case and at which company take a lot of digging and you need inside info that can only come from talking to someone already at one of the companies or that recently left. That's where I would start -- speak with as many of those contacts as you can and zero in on the right target -- then build as many warm intros as possible at the target.
