Why We Invest in Open-Source — The Geseidl Philosophy

This quote defines everything we do at Geseidl — including how we approach open-source. It is not about marketing or public image. It is about the conviction that shared expertise generates more value than hidden expertise.

Open-source as a natural extension of the Geseidl philosophy

The Geseidl Group was founded on the principle that every contribution must count — makeitcount. This principle applies to client services, internal work, and community contributions alike.

When a team of accountants helps a client optimize their business fiscally, that expertise is valuable. When a developer solves a problem in an application's code, that solution is valuable. But if the solution can help others too — why keep it only for ourselves?

Open-source is the natural answer. We publish our solutions, document them, test them, and offer them free of charge to anyone who can use them.

What it means concretely

Our investment in open-source is not abstract. Here is what it includes:

• Free tools — applications and libraries anyone can download and use at no cost. From remote connection managers to AI skills for legacy languages
• Verifiable code — all our open-source code is public on GitHub. Anyone can see how we work, how we test, how we document. There is no "secret code" or "proprietary algorithms" — just transparent engineering
• Open documentation — not just code, but scientific papers, implementation guides, lessons learned catalogs. We document even our mistakes, so others do not repeat them
• Upstream contributions — not just isolated forks. We send changes back to original projects for the benefit of the entire community

Not just charity — a demonstration of competence

There is a pragmatic benefit of open-source that we do not hide: it demonstrates real competence.

When a potential client evaluates us, they can do something they cannot do with any of our competitors: verify. They can see our code, our tests, the way we solve problems, how we respond to feedback. They do not have to take our word for it — they can validate it themselves.

A SonarCloud badge with A/A/A on a real project with 6,175 tests says more than any marketing brochure.

The connection with makeitcount

The makeitcount philosophy means that every action must generate impact. Open-source is the ultimate impact multiplier: you write the code once, but its value grows with every user who adopts it.

A tool used by an IT administrator in Berlin, a developer in São Paulo, and a support team in Tokyo — from the same initial investment. That is the definition of "make it count."

We see open-source not as a cost, but as an investment. An investment in reputation, in community, and in the idea that good things deserve to be shared.
