This document summarizes Kimmo Koivisto's presentation on business model innovation. The presentation discusses what a business model is, why business models matter, and provides examples of classic business model cases for inspiration. Some examples discussed include JC Decaux's earnings logic model, Ryanair's low-cost model, Hilti's tool rental "as a service" model, Minute Clinic's standardization model in healthcare, and Threadless' co-creation model leveraging online communities. The presentation emphasizes that startups should focus on innovating radical new business models, and established companies often fail because they prioritize products over reinventing their business model.
