MJB Seminars is one of Australia’s longest-running personal development companies. Founded and led by Mitch Behan and Emilia Tomeo out of Perth, MJB has been running experiential seminars, coaching programs, and international retreats for over 25 years. More than 50,000 people have attended their events. They hold 854+ Google reviews at 4.9 stars. Their Instagram following sits at 86,000+.
MJB had built something remarkable over two decades. A loyal community. A proven methodology in the Equilibration Process. A reputation that filled rooms in Perth through word of mouth alone. But the business was at an inflection point. The personal development industry was shifting fast: rising ad costs, digital-first competitors, growing consumer scepticism toward free seminar models. MJB was ready for the next chapter but needed a strategic partner to build it.
When Mamba came on board in June 2024, the scope was paid media execution with a very healthy budget per event. That scope expanded quickly once it became clear the opportunity went well beyond running ads.
