I am launching a new online marketing platform that will allow brands to connect with (potential) customers globally in a completely new way. The biggest component of the business is partnering with various large and medium size brands that are willing to experiment with their marketing approach and product offerings.

Until now, I was working on devising the business plan and the operational aspects of it but now is the time when I have to penetrate the C-Suite, specifically the Chief Marketing Officer suite at those brands with my partnership proposal. I am not sure how to go about it.

Do I sent emails, pick up the phone, send letters? Do I prepare a “pitch deck” that I email the brands or send them or a top view summary page? I am totally unconnected to those brands and they span across various industries. Any ideas or insights would be appreciated!
