01 · Background

A quarter century of search and web work

Thomas built his first websites in 2000 as a lead SEO and web developer. Since then he has run his own companies, managed development projects at Webhuset, and advised clients on search at Argo Internett.

In 2015 he co-founded Mementor AS, the agency behind this suite. He became CEO in 2022. The agency works with SEO, AEO, Google Ads and web design for Norwegian and international clients every day.

That daily client work shapes these tools. Features get tested on real sites with real rankings at stake before they ship here.

Thomas holds certifications in Google Ads and Google Analytics, plus the Semrush for Digital Agencies certification. He studied network and system administration at Næringsakademiet in Tønsberg.
