Notum is a headless CMS development agency and an official Enterprise Partner for both Strapi and Payload, certified under ISO/IEC 27001. Notum builds, implements, migrates, and maintains enterprise-grade platforms for teams that can't afford to get it wrong, whether that means a never-ending project, a blown budget, vendor lock-in, or lost search traffic once it's live. The work often spans multi-site, multi-brand, and multi-language setups. Notum's clients include AXA, Siemens, Scenic Group, Konica Minolta, Lokalise, and even Strapi's own website. The team also contributes several open-source Strapi and Payload plugins, including the Strapi + Next.js Starter.
