Practical marketing knowledge built from 25+ years of doing the work.
I've spent 25+ years helping companies grow. That journey has taken me from building my own ecommerce business to leading marketing programmes for brands including Nokia, Virgin Media, QVC, Accenture and Royal Mail. Along the way I've managed budgets from zero to £65 million, launched products in more than 90 countries, driven millions of app downloads, generated millions in revenue and worked with over 100 organisations ranging from startups to global enterprises. Today I run Growth Hakka, where I help founders, CMOs and marketing teams combine growth marketing, AI, automation and data to build leaner, faster growth engines. The courses, frameworks and playbooks you'll find here aren't academic theory. They're built from real campaigns, real budgets, real mistakes and real results accumulated across more than two decades of marketing, digital transformation and growth. My goal is simple: Help ambitious marketers learn in weeks what took me 25 years to figure out.
