The aim of this research is to provide perspectives on how entrepreneurial practitioners, specifically owners of high-tech small firms (HTSFs), engage with knowledge transfer and learn. The authors draw on extant research and report on the views and observations of the principals in two case study companies in the HTSF sector with regard to growing their ventures and developing learning while part of a Knowledge Transfer Partnership (KTP) programme. Entrepreneurial learning is an area of significant interest due to the growth of entrepreneurship and the varied ways in which learning can take place. There are many different interventions that can be used to transfer knowledge and develop learning, but there is limited, if any, consensus on their respective effectiveness. The researchers used an ethnographic approach in two companies over an 18-month period. The study concludes that the KTP intervention facilitates an opportunity for learning through disruption, with the key barrier to any new learning being established practice. Interestingly, the findings suggest that entrepreneurial learning is greatly facilitated by 'on-the-job' learning.
