According to Greek mythology, the hero Jason built a ship and named it Argo. With his comrades, the Argonauts, he left on a quest for the golden fleece. Poseidon, the god of the seas, protected and safely guided their journey.
About 4000 years later, Jason Robbins started an open source project for a UML modeling tool and named it ArgoUML. Many others joined him in this adventurous undertaking, including a group of software developers lead by Marko Boger, who was at that time a researcher at the University of Hamburg. Together they greatly advanced the tool. After Jason Robbins shifted his focus to other tasks, the developer group evolved to become leaders of the project. Under their guidance and with their advances, ArgoUML became highly popular. They realized the great demand for a tool like ArgoUML, as well as the amount of work necessary to shape it into a professionally usable tool. They finally took the risk of starting a company with the goal of bringing the most usable tool to a broad audience. With respect to their open-source origin, the company is called Gentleware and their tool is called Poseidon for UML.
That is who we are and how our quest started. Today, Poseidon for UML is one of the most popular UML modeling tools on the market. Our special focus is on usability and on making the job of modeling a joy.
Software development is a creative process. It requires a deep understanding of the problems to be solved, the involved users and stake holders and their requirements, the ability to find the right level of abstraction from reality, and the creativity to shape a software solution. At the heart of software development is the human being. Our goal is to provide tools to increase his creativity and productivity. Tom DeMarco found a word for this: Peopleware. This point of view is engraved in our name. Gentleware is the connection between humans and the software they develop. Our main subject is the development of tools for UML, Java, MDA and XML with a strong focus on usability and high productivity. We also offer training, consulting and individual solutions.
