OpenView Labs supports expansion stage startup companies with a strong offering of expert support to portfolio companies. They have decided to open up their experience and expertise to all who are interested after working with agile practices and implementing Scrum in most of their companies during the past three years.
The web site is packed with useful information like a rigorous analysis of why you should dump all those worthless job descriptions that are messing up your company! Of course, you probably have already got rid of time sheets that reduce productivity. But I bet you still have performance appraisals which are proven to demotivate employees!
There is a lot you can learn from this site whether you are a software developer or the CEO of a company.
