AI-Ready Websites, Right the First Time

CMS migrations don’t have to drag on for months or eat your Christmas party budget. We deliver Strapi and Payload CMS platforms for teams that can’t afford to get it wrong.

What You Get with Notum

Whether you're getting ready for AI search, leaving a legacy CMS, or building something new, you get the strategy and the delivery from one team.

Let's Talk About Your Project

AI Search Optimization

Your next visitor might be an AI agent. We structure your content so ChatGPT, Perplexity, and Google's AI answers can read it, quote it, and send people your way. AI speeds up the work. Our people make the calls.

Headless CMS Migration

Migrations are most of what we do. We know the code of Strapi and Payload CMS inside out, and we've turned the repetitive parts into ready-made automation. You move faster, and your new site usually loads faster and ranks better than the old one.

Why Teams Choose Notum

You Know Who You're Working With

No subcontractors and no handoffs between offices. The people you meet at kickoff are the people writing your code, and the ones you call when something comes up.

Every Project Has to Succeed

We take on only a handful of projects a year. That keeps senior people on your project and leaves no room for one that just limps across the finish line.

Your Team Comes Out Stronger

You lead, we deliver, and the know-how stays with your team. Your developers, editors, and marketers understand what was built and why, and they carry those skills into whatever they take on next.

About Notum

We started building with Strapi in 2018 and later made Payload CMS our second core platform. Today, we work with clients in 13 countries, collaborate closely with both core teams, and build our own open-source tools.

Find out what drives us, what we value, and why clients keep coming back.
