Built by

Stefan Maritz

A seasoned brand strategist, content leader, and AI-native content engineer - currently building out content operations for one of the world's leading fintech companies.

Contengi is the accumulation of everything I've learned building brands and content systems over the past decade. Every framework, playbook, and hard-won insight - packaged into a platform you can actually use.

My mission is to give small companies and founders the same content infrastructure that large teams take for granted. I work directly with every customer to set up their system and knowledge base - and I'll personally train you and your team.
