We are not an agency that simply executes. We are a team that thinks ahead, challenges assumptions and gets the most out of every project. For over two decades, we have been developing digital solutions for Swiss companies – with the precision of a watchmaker and the curiosity of a startup. 784+ projects. 15 heads full of ideas. And the commitment to treat your project as if it were our own.
Sidora AG was founded in Zurich – with a simple conviction: digital solutions must not only work, they must inspire. Not the designer, not the developer, but the client who works with them, and the end user who experiences them.
We are 15 designers, developers and strategists who think, code and present in five languages: German, French, Italian, English and Albanian. This is no coincidence – it is our bridge to the multilingual Swiss market and to international clients.
What sets us apart from other agencies? We don't think in assignments. We think in partnerships. Every project that comes to us is treated by our team as if it were our own company. We challenge briefs when we believe there is a better way. We propose solutions that go beyond the brief. And we don't stop optimising until the result is not just good, but the best that was possible within the available budget.

We don't simply execute what's in the brief. We dive into your business model, understand your customers and challenge assumptions. The result: solutions that don't just work technically, but drive your business forward. Proactive, not reactive.
Not every company has the budget of a major bank. But every company deserves the best possible result within its means. We advise honestly, prioritise wisely and don't waste a single franc on solutions that add no value.
Technology is changing faster than ever. We continuously invest in training, test new tools and methods, and implement standards that are relevant not just today, but three years from now. From PHP 8.4 to GEO optimisation: we are where technology is heading – not where it was.
We don't build websites and disappear. We accompany our clients long-term: with proactive maintenance, continuous optimisation and an open ear for new requirements. Many of our clients have been working with us for years – that is the greatest compliment we can receive.
Let's find out in a personal conversation whether we are the right fit.
No waterfall, no chaos – but agile sprints with a clear plan, short feedback loops and a dedicated point of contact.
Technology-neutral: We recommend the CMS that fits your project – not the one we know best.
Design & code united: Designers and developers sit at the same table. No media breaks, no surprises.
Swiss Quality: Swiss hosting, Swiss standards, consulting in your language – with an international perspective.

784+ projects speak for themselves. Let's discuss your next project.
Sidora AG is not an agency owned by an investor or a holding company. It is owner-managed – and you can feel that in every project.
Owner management means: short decision paths, personal responsibility and a team that doesn't work for quarterly numbers, but for the pride in the result. If something isn't right, you don't call a hotline – you call us.
The "friendly and accommodating nature of the owner" that our clients consistently highlight is not marketing – it is part of our DNA. We believe that the best results come from respect, openness and genuine interest in each other.
Better inspired, differently motivated – that is not just our claim. It is the promise we fulfil anew every day.
Sidora is an owner-led digital agency from Winterthur. Since 2003 we have completed more than 780 projects — from small company sites to large platforms. This experience benefits your project directly.
At our agency, people who understand their craft and enjoy explaining what they do work for you. You speak with the same people who carry out your project — no long chains of command and no empty promises.
We are independent and recommend what really fits — not what brings us the most. Quality, reliability and an honest approach matter more to us than the quick deal.

We are 15 experts: designers, developers, strategists and project managers. Large enough for complex enterprise projects, small enough for personal relationships and short decision paths.
We are technology-neutral and recommend the system that is optimal for your project. Our core competencies include Craft CMS (Verified Partner), Statamic, WordPress, Laravel, WooCommerce, Craft Commerce and Shopify Plus. On the frontend, we use Tailwind CSS, Alpine.js, React and Next.js.
No. We serve clients across Switzerland and internationally. Our team speaks German, French, Italian, English and Albanian. In-person meetings are possible in the Zurich/Winterthur region, all other projects are coordinated remotely.
We combine the expertise of a specialised agency with the agility of a startup. With us, there is no agency overhead: short paths, direct communication, and the owner is involved in every project. At the same time, we bring the experience from 784+ projects.
Yes – that is one of our core values. We offer monthly maintenance packages with security monitoring, updates, performance optimisation and personal support. Many of our clients have been working with us for years.
Absolutely. We even recommend starting with a manageable project to get to know the collaboration. If it works out, we grow together.
We look forward to your project and to a conversation at eye level.
We are where our clients are: in the Zurich economic region. In-person meetings, workshops and presentations are a matter of course for us – digital or on-site.
