About Tweede golf

We are a close group of engineers and developers with a background in cyber security, mathematics and computer science. We find it important to work in an environment in which we continuously improve our engineering skills and challenge each other. At the same time, we are a long-term agency: for colleagues as well as for our clients. As far as we are concerned, attention for each other is the key.

What we do

Our domain is safe software: writing safe and privacy-friendly software is the common theme in all our work. We're here to make sure security is a thing from the get-go, not an afterthought.

We operate best when we are allowed to turn innovative ideas or technologies into safe, production-ready software. We do that for (and in collaboration with) tech start-ups, governments and universities & foundations.

Our open-source toolbox includes Node.js, Rust & Embedded Rust, Go, React, Symfony and Flutter.

How we see the world.

Software has been built the wrong way for 10 years. That's why these days, our industry spends most of her time patching the leaks.

Now that our lives have become highly digitalized we experience the consequences of unsafe software and poorly protected data every day. It is about time to reevaluate our priorities.

We believe that the design of safe and privacy-friendly software is the responsibility of all software builders, whether you are a freelancer, an agency or big tech.

Security and privacy thus become the domain of software makers, not just that of pen testers and consultants.

An ounce of prevention is worth a pound of cure - even more so in software.
