I'm currently managing and facilitating the Validos-collaboration – it's an open collaboration of companies for open source compliance. Validos does the basic validation of open source software packages and shares the results with every participating company/entity. Thus the basic work is done only once. I have introduced the idea and our law firm provides the compliance work. Validos is essentially a collaboration between our customers and new customers.
From our customers' perspective the business model is great. They get the traditional outsourcing benefits (expertise and scale) and most importantly, they do not need to redo work done by some other company. With a growing number of members and a growing database, the work needed per customer becomes smaller all the time.
