Custom Order Software Intelligently Crafted
Software that works.
Today and long-term.
Custom-built software from Switzerland
One-time at a fixed price and
ongoing support via subscription.
This is COSIC.
100 % custom. Every line of code is written for you.
Security without compromise
Every line of code follows the highest security standards · ISO-compliant down to the last detail.
Audit-ready
Every project fully documented · requirements, architecture, processes, handover. Audit-ready at any time.
Clean design
Clear interfaces, focused on what you need.
Intuitive to use
Software that explains itself · with an in-app manual you'll rarely need.
Your code, your property
Full control, full freedom · it all belongs to you.
Direct contact
One person, personal and fast.
Professional from the start.
Software that lasts needs more than a good prompt.
The invisible gaps
API keys in source code, open endpoints, missing validation · what looks functional at first glance is often wide open.
Code someone understands
When the creator leaves and no one can read the code, every small change becomes a risk. At COSIC, code is written to stay maintainable.
Maintainability over throwaway code
Technical debt accumulates invisibly. Eventually, every change costs more than the original build.
Built to scale
Architecture that scales from 10 to 10,000 users · designed from the start.
Law & regulation
GDPR violations, missing accessibility, broken licenses · what gets overlooked can get really expensive.
What happens at 2 AM?
When the system goes down, it doesn't matter how fast it was built · what matters is whether someone is there who understands it and can fix it.
Who is behind COSIC?
Behind COSIC is me · since the mid-90s I've been building digital solutions that work. I think in systems.
Starting with websites in the mid-90s, programming languages followed through IT training. Since then, software development has accompanied and strengthened every step of my career. Professionally, I'm at home in Supply Chain Management.
Since 2021 I work exclusively with Linux. Since 2022 I stay continuously up to date with the latest AI technologies. I apply systems thinking to every industry. My standard: make results visible, keep functionality intuitive, never overwhelm.
