About us

We operate websites.
Including our own.

Mr.Site is a subscription website service for trades and small businesses, founded in 2026 and operated by Collective Brain GmbH in Hamburg, Germany. Your plan covers design, hosting, maintenance, SEO and AI visibility for one monthly fee.

The name is older than the service. A British website builder of the same name shut down in 2020. Mr.Site has no connection to that company or its former product. What you see here has been built and run by Collective Brain GmbH in Hamburg, Germany, since 2026.

Mr.Site grew out of running things. Our team has been building and operating business websites, blog systems and visibility infrastructure for years. Several hundred websites run under our care today, many with fully automated editorial and SEO processes. Yours would join a well-practiced routine, not an experiment.

This shaped a conviction: a website is not a project you finish. It is infrastructure you operate. That is exactly what we offer you, as a subscription, at a price your business can plan with.

Your website gets the same tools we use to keep our own brands visible: modern static websites, structured data, AI-assisted editorial work with human approval, continuous measurement in Google and in AI answer engines. What all of that means for your subscription is listed on our plan overview.

Who is behind this

Mr.Site is a brand of Collective Brain GmbH.

Behind the subscription is a digital agency from Hamburg, Germany, with our own developers, our own designers and our own film crew. We have been building and looking after websites for 8 years, for one-truck shops and for large enterprises alike. We know what a small business needs: the phone should ring, and the site should keep running without you having to think about it.
