Founder | InsightRiot.com. Co-founder of some other stuff. I've helped clients / partners reach over 100MM people globally. My magic ability is to architect (strategize) more impact (and income) for speakers, authors and thought leaders.
Designing your positioning, products and platform in a way to give you uncontested market space, truly engaging products and a footprint that attracts and builds your community around your unique abilities.
Start with those who influence your audience. Target 'coaches to the coaches'...people who train speakers, etc. Leverage all their hard work at amassing a community by doing some account based marketing to those people; strike up partnerships; get some beta user feedback (and testimonials). If you have a solid product, it's a pure value add to their audience.
You can also target those communities with paid traffic and then just a matter of tweaking the metrics to make the numbers work. (Spend < Revenue)
And for what it's worth, I develop products with speakers, authors and thought leaders. Happy to take a peek at what you have and provide feedback.
