George Ten is a copywriter, educator, and strategist known online as @GrammarHippy. He invented the 'CopyThinking' philosophy — the contrarian belief that great copy is 90% strategic thinking and 10% actual writing. With 11 years in marketing, he has helped build 8-figure info-product funnels, sold over 500,000 products online, and spent $10M+ profitably on Facebook ads. He teaches thousands of entrepreneurs on X/Twitter and through his courses and community.
Joanna Wiebe is the founder of Copyhackers and the originator of conversion copywriting — a discipline she coined in 2011. Over nearly two decades, she has trained 70,000+ professionals and consulted for brands from bootstrapped startups to Fortune 100 enterprises including AWS, Canva, and Shopify. Her first traditionally published book, The Copyselling System, is set for release in July 2026 via BenBella/Simon & Schuster.
