Why did we create eYssen?
In 2025, we decided to fork the Odoo Community Edition and launch eYssen and the eYssen Cloud platform. The reason behind this decision lies in the ongoing changes to Odoo’s business model, which increasingly pushes customers towards the Enterprise Edition and SaaS, while limiting the freedom of Community users and partners.
Many features that were once available in the Community edition have gradually been moved to the Enterprise version. Licensing terms became stricter, and the official SaaS approach left less flexibility for partners to operate their own services.
What once began as Fabien Pinckaers’ vision – a truly open ecosystem, led by partners, empowering businesses with freedom and flexibility – has gradually turned into a closed, vendor-centric SaaS company. While Odoo has grown into a global success story, it has also steadily distanced itself from its original open-source philosophy.
eYssen, however, carries forward that earlier vision: a commitment to openness, independence, and long-term trust with clients and partners.
