About
20 years of real-world craft — married to AI.
Two decades of marketing, web, and automation know-how, combined with the AI that's actually shipping today. We bring the practical experience and the cutting edge — at the same desk.

01 / Story
How a Swedish side-project became an AI studio.
Mediseo started in 2018 as a side project — a Swedish founder helping local SMBs in the Nordics ship the digital systems they couldn't get from generic agencies. By 2019 we were building marketing sites and SEO programmes full-time, working from Sandefjord. ChatGPT shipped in November 2022, and we started integrating LLMs into client workflows the same week. The Málaga desk opened later, in 2022, as our first European base outside the Nordics — but Sandefjord remains where the work happens.
How we got here
- 2018
Founded
Swedish co-founder starts taking on digital projects on the side. First clients are local clinics and SMBs across the Nordics.
0 - 2019
SEO & web, full-time
Mediseo becomes the day job. We set up shop in Sandefjord and start shipping marketing sites, SEO programmes and lead engines for clients across Norway, Sweden and Spain.
1 - Nov 2022
AI from day one
ChatGPT ships. We start integrating LLMs into client workflows the same week — long before 'AI agency' was a category.
2 - 2022
Málaga desk opens
We incorporate Mediseo formally and open a base in Málaga — our newest addition, and our southern-European outpost. Sandefjord stays the main base.
3 - Today
Operating system, end-to-end
AI implementation + marketing + automation as one integrated operating system. Model-agnostic — Claude, GPT, open-source — whatever fits the job.

International team, broad network.
Small core, deliberate. Every engagement is run by a partner — no juniors fronted to senior accounts. Swedish founder, Norwegian base, Spanish desk, with a network of specialists we trust on tap.

Leave with a number, not a deck.
Thirty-minute call. We listen, we name the loops you'd hand off first, we name a price. No deck, no roadshow, no twelve-month programme — just the next concrete thing to ship.
