This presentation discusses profit models and was created by Ziya Boyacigiller, a leading angel investor and mentor in Turkey. It outlines 22 different profit models, including customer solutions, product pyramids, installed base, brand, and low cost business models. Examples are provided for each model to illustrate how companies have designed their business to target profit growth rather than just unit volume growth. The presentation encourages businesses to shift their focus to identifying more valuable opportunities and strategic control points in the value chain.
