About.

Bio · 2008 — present

I founded COSEOM in London in 2008 and moved the company to Barcelona in 2017 — where I’ve been based personally since 2005. Before COSEOM: IT and security work at Citi and T‑Systems, plus consultancy projects across Germany and Spain.

For seventeen years the agency has run multilingual paid‑media and SEO programs for B2B companies expanding internationally. Today the team works out of Barcelona, San Francisco, Stuttgart and Bangkok — virtual offices for the markets we ship into — in English, Spanish and German, mostly for SaaS, cybersecurity, legal‑tech and fintech clients.

Most of my time now goes into integrating AI agents into how the team operates — bid management, reporting, competitive monitoring, structural content production. The interesting question is which parts stay human and which don’t.

The agency is at coseom.com. This is the personal site.
