A development team from Bern. Since 2016 we have been developing and operating online platforms on our own stack, from the first line of code to ongoing operations.
We are not a web agency that processes projects and passes them on. We specialise in projects with high demands on security, availability and compliance.
More than ten years of development on a modular platform stack. Around 60% of a typical platform is in place from day 1. Symfony, Sylius, API Platform: assembled into a modular system.
Platforms are not just built and handed over: we take long-term responsibility and operate the infrastructure ourselves. Monitoring, updates, support and further development are part of our core business. Operations are not an add-on service but the norm.
Certified to ISO/IEC 27001. The ISMS covers development, hosting and operations. Audited annually, infrastructure on our own virtual servers in the Swiss Virtual Data Center.
The stack is built on open source products: Symfony and proven community technologies, with no proprietary core components from third parties.
A broad IT offering has become a development team with its own stack and a clear focus on platform development.
Christian Knellwolf founds cloudtec GmbH on Sandrainstrasse in Bern. Services: IT consulting, cloud solutions, web design and web applications.
The team grows. We start developing with Symfony.
After the first years of finding our direction, we specialise in platform development.
The first version of the stack is created. We learn our lessons from the first platform projects.
cloudtec GmbH becomes cloudtec AG.
The stack is rebuilt from the ground up: one foundation for many platforms.
We acquire Mediacoding GmbH and concentrate further on platforms and corporate websites.
We expand the management board with a COO and a CTO.
The management board is expanded to include a CXO (Chief Experience & Product Officer).
After many years at Sandrainstrasse 17 in the Marzili district, we have been working at Wabernstrasse 40 in Bern since 1 February 2026.
We pass our first certification to ISO/IEC 27001.
The third generation of the stack is close to completion; rollout follows from 2027.
Development, architecture, operations, design and project management. We all work together in Bern. A strong team that looks out for one another and cares about good work.

Once a year, cloudtec moves its office abroad for a week. That week, the whole company works together from a new place, often with workshops in the mornings.
In a team of just over twenty people, everyone knows each other, but rarely outside work. During this week, people get to know each other better while cooking together or over an after-work beer.
Grumpy morning people, early risers, hidden cooking talents: the week reveals quirks that enrich everyday life in Bern. Team members become more approachable, and working together comes more naturally.
Discovering a foreign culture and cuisine together, going on excursions, sharing new experiences. That strengthens the sense of belonging beyond the work context.
Pictures from past Office Relocations: 2021 Robion in France, 2022 Sevid in Croatia, 2023 Valencia in Spain, 2024 Athens in Greece, 2025 Lisbon in Portugal and 2026 Florence in Italy.
How we work, what we build and what we want to be measured by. Posts from the development team.
Office Relocation by train for the first time. A week in Florence: three workshops, the Mercato Centrale and a cooking class on Friday.
Information security with documented and audited processes, and what the road to an internationally recognised certification demanded.
New address: Wabernstrasse 40, Bern. An office move, a data centre switch and a team that managed both in the same winter.
Whether as a developer in the team or as a client with a platform idea: there are different ways to work with cloudtec.
