Yannick Seiller and François-Xavier Guidet.

Yannick Seiller
CEO – FactorFX
Passionate about Open Source, Yannick Seiller has dedicated more than fifteen years of his career to helping grow the ecosystem in France.
At the helm of FactorFX since 2012, he has built a company that combines software publishing and Open Source integration, supporting both SMEs and large public-sector organisations.
A committed Open Source advocate, he actively contributes to several leading projects, including OCS Inventory, ITSM-NG, Proxmox, Bekane and MyB’Suite, driven by a pragmatic vision: making Open Source software a true lever for performance, digital sovereignty and trust for organisations.
In 2024, he helped launch the Open Source Experts collective, alongside Worteks, Bluemind, Arawa and Inno³. The alliance is built on the belief that cooperation between Open Source players is key to creating a credible and sustainable alternative to cloud giants.
Close to the field, he draws on his experience working with CIOs, local authorities and large enterprises to bridge the gap between strategy and operational reality. Behind his straightforward, down-to-earth approach lies a clear ambition: to promote a free, sovereign and innovative digital world.
François-Xavier Guidet
CTO & Co-founder – FactorFX
A telecommunications and network engineer by training, François-Xavier Guidet began his career in the United States before returning to France to found FactorFX in 2006. He has built a unique company at the crossroads of integration and publishing of open-source solutions. Naturally curious, he envisions FactorFX as a laboratory for ideas and solutions centered around open-source infrastructures.
Under his technical direction, the company actively contributes to flagship projects such as OCS Inventory, MyB’Suite, Proxmox, ITSM-NG, Bekane and OpenNAS, combining technical rigor and a culture of sharing.
Known for his ability to connect architecture, performance, and usability, François-Xavier makes it a point of honor to share his knowledge. A regular speaker at major open source events, he shares his experience as an entrepreneur and committed contributor.
Guided by the conviction that open collaboration is the engine of technological progress, he continues to advocate for a digital world where control, transparency and community take precedence over dependence and complexity.
