Paper prepared for the workshop on The Economics and Business of Biosciences & Biotechnologies: What can be learnt from the Nordic Countries and the UK? This paper examines venture capital firms ’ investment patterns in the biomedical sector in the Stockholm Uppsala region from 1996 to 2002. The investments that venture capital firms make form network patterns around the biomedical firms. The investment network illustrates a rather dense network with several overlapping ownership ties between firms. The paper discusses effects of investment networks and how venture capital firms use these networks. The argument is that the most central venture capital firms combine and connect resources in their network in order to increase the value of their portfolio firms. The venture capital firms function as “bridges ” in the network and use their network position when possible to combine the resources. This might for example lead to consolidating activities between biomedical firms, having the same owners, encouraging firms to use the same suppliers, and recruiting CEOs to serve on the other portfolio firms ’ boards etc.
