In the part about business models, Open Life contains a chapter titled Glass House, a totally transparent company (fictitious). As the title already gives away, it is my fictitious vision - a utopia, if you will - of a radically open business model, where even the tendering process and financials of the company would be publicly available.
The New Inspirer reports on a business model not at all like that, but this was really inspiring to read:
Entrepreneur Sanne Roemen never makes an invoice. She lets her clients decide what they want to pay her. And how they want to pay her. Sanne, who consults on how companies can apply web 2.0 principles in their business, knows by experience by now that clients generally pay her three times as much as she would have offered before the job was done. The side-effect of clients paying less than expected therefore isn't too much of a problem. 2I can't determine for the client what the value of my services is. That's something which is different for everybody".
