Technology Market Intermediaries (TMI) are currently emerging on the markets for technologies attempting to realize business opportunities and facilitate the technology and IP transactions supporting firms and other markets actors (e.g. universities). They aim to support open innovation, respectively facilitate more economically technology and particularly IP transactions. However, our understanding of TMIs and their roles needs to be considered incomplete. In this paper I provide evidence on the growing number of TMIs and derived a conceptual basis for a further understanding of TMIs. The inherent difficulties of intellectual property monetization present a challenge for technology based enterprises and business opportunities for IP firms. Following a literature review, I develop a typology for TMIs. Having carried out a review of the literature I compiled a mix of primary and secondary data on about 70 TMIs. Applying the 'nine business model building blocks' from Osterwalder (2004) I identify 12 different TMI types which I then consolidate into six TMI archetypes using the framework for 'business models archetypes' of Herman and Malone (2003).
