Fall asleep beneath living northern lights. Eight worlds in real time, sounds you mix yourself, and a gentle wake-up. Plus sleep tracking, a breathing exercise and noise, in 31 languages and without an account.

Built ourselves. With care.
We do not only advise, we publish. Both apps were made entirely in house: concept, design, code and store presence. What we learn doing it goes straight back into every client project.
Our homage to the landing games of the eighties: fire the thrusters, land gently, pick up passengers. 20 handbuilt levels, three taxis, no advertising and no subscription.

Our master platform. What began as a forum for people building a house has become a toolbox: thirteen calculators that turn a question into a number you can back up.

Screenshots of the platform, 9 September 2026.
Thirteen calculators instead of thirteen promises.
Every tool returns a figure with a source behind it — from an aerial photo of your own roof to the deadlines in all 26 cantons. Free for owners and builders, and no account is needed for a result.

Six communities where people actually talk.
We have been running our own Swiss forums since 2002. They grew, they were not bought: every post comes from somebody who had a question or knew an answer. Their magazines and company directories offer further guidance.


haus-forum.ch
Online since 2004Building, living, garden, renovation
The busiest of our platforms: people who are building, converting or renovating compare quotes, tradespeople and technology here. Alongside it a magazine, a company directory, calls for tenders and thirteen tools for calculating and comparing.


digi-tv.ch
Online since 2002Television, streaming, internet, home cinema
One of our oldest forums, on air since 2002. Television, cable, IPTV, streaming and home cinema: anyone wanting to know which provider is actually any good reads up here.


liebeskummer.ch
Online since 2002Heartbreak, separation, relationships
The largest of our communities by post count. People write about separation, doubt and starting again, often anonymously and always moderated. A place where somebody listens.


armeeforum.ch
Online since 2007The Swiss army: recruitment, basic training, career
From the recruitment process through basic training to a military career. Serving and former members answer the questions the official leaflet leaves out.


haustierforum.ch
Online since 2005Cats, dogs, rodents and other pets
Keeping, health, training and everyday life with animals. Much of it consists of first-hand accounts written over years, of a kind no brochure carries.


trader-forum.ch
Online since 2011Trading and markets
Equities, commodities, currencies and the question of which trading platform is worth having in Switzerland. The smallest of our communities, with one clearly defined subject.
Why advertising works here
People reading these forums are usually in the middle of a decision: replacing a heating system, switching provider, taking in a dog. Advertising here meets attention that is already there.
The content has grown over more than twenty years and sits in search results. A post written today will still be found in years — and with it everything next to it.
On top of that come the platforms’ own newsletters, which land directly in the inbox.
What can be booked, and what it costs, is on the advertising page of each platform. That is where it is maintained and where it is current.
- 430’000
- visitors per month
- 1’600’000
- page views per month
- 30’000
- newsletter recipients
From the media data of haus-forum.ch: server statistics (AWStats, robots excluded and cleaned), as of September 2026. We publish no visitor figures for the other platforms.
How a project runs with us.
Concept
We listen and write down what is to be built: features, audience, scope. What you end up with is a document you could hand to somebody else.
Design
The concept becomes screens. You see early how the product feels, and can change your mind while it still costs nothing.
Development
We build in short rounds with working intermediate versions. What is finished you can try out instead of imagining.
Growth
Release is where the work starts: measuring, sharpening, becoming visible. We stay alongside for that if you want us to.
Your website.
A conversation away.
We build your website. With AISphere, you update content by talking to an AI assistant: revise text, add images and change information.

Let us get something moving.
Tell us what you are working on. You will get an honest assessment back: what is possible, what it takes and what it costs.
