The questions are as follows: 1. Consider a hypothetical (not real) startup platform, name it, and sketch its business environment (in which sector, who are the (real) competitors, what are the customer groups, etc.?). 2. Based on your answer to question #1, evaluate the network effects and multihoming opportunities in the industry. 3. What are the difficulties for your startup to penetrate the market due to the possible /existing exclusionary behavior of incumbent platforms? Please, evaluate at least one of them. 4. Are there any data-related competition issues (collection, portability, or interoperability) the market? What are the possible effects on your business? 5. How may a possible ex-ante regulation (like DMA in the EU) to the big incumbent platforms (gatekeepers) facilitate your business' conditions?
