Openmoko
Welte was Lead System Architect for Openmoko, a project to create a smartphone platform using free software. It uses the Linux kernel, together with a graphical user environment built using X.Org Server, and the Matchbox window manager. The OpenEmbedded build framework and ipkg package management system are used to create and maintain software packages.
However in 2007, Welte announced his withdrawal from Openmoko, citing internal friction and demotivation. He continues to contribute as a volunteer to the project.
