We are launching Summer 2016 and want to get started now.
Great approach! Many people don't realize that campaigns must be created and implemented well ahead of time. Growth hacking for example takes time and a lot of diligence, many think is a quick solve all approach to marketing but contrary to that!
I would be willing to help you if you have any questions. I have done several growth campaigns with significant results, you didn't seem to post a question tho. :)
I'd love to help you! I helped 100's of authors plan successful book launches through my company www.publishyourgift.com. It's good that you're already thinking about how to build your platform, before the actual release. That's a vital component! Let me know if you have any specific questions, or just go to the link above to schedule your free consultation.
