Joanna Wiebe

Profile

Joanna Wiebe is the founder of Copyhackers, the resource that effectively created the conversion copywriting category. Her methodology — grounded in voice-of-customer research, A/B testing, and deep psychological understanding of buyer motivation — has become the standard approach for growth-focused marketers across Europe. Wiebe's influence is particularly strong in the SaaS sector, where her frameworks for onboarding copy, email sequences, and landing page optimisation have helped hundreds of European startups dramatically improve their conversion rates. She has trained over 40,000 copywriters and marketers through her courses and workshops, and her blog remains one of the most cited resources in the industry. Her approach is rigorously empirical: every claim must be tested, every assumption must be validated against real customer language. This scientific rigour, combined with genuine creative skill, makes her one of the most respected voices in European digital marketing.
