Modern Monopolies by Alex Moazed and Nicholas L. Johnson, published in 2016, is a business book about platforms: companies that make money by connecting groups of people instead of making goods. Moazed founded Applico, a firm that builds and advises platform businesses, and Johnson worked there as a researcher. Their argument is that the most powerful firms of this century win by owning the means of connection, the way industrial giants once won by owning the means of production.
What is Modern Monopolies about?
The authors start by splitting businesses into two kinds. Linear businesses make or buy something and sell it down a chain to customers. Platforms create value by matching producers and consumers and letting them trade, chat or share. Uber owns no cars, Airbnb owns no rooms and YouTube makes almost none of its videos, yet each controls the place where supply meets demand. Because adding a new user costs a platform close to nothing, the winners grow fast and tend towards winner-take-all markets.
The book then sorts platforms into two families. Exchange platforms match people for a direct interaction, such as a ride, a date or a freelance job. Maker platforms give producers tools to reach a large audience, such as app stores and video sites. For each type the authors walk through the same questions: who the producers and consumers are, what single transaction repeats between them, how the platform builds trust and how it makes money without choking that transaction.
The final part looks at why platforms fail and how traditional companies respond. The authors argue that most incumbents try to bolt a platform onto a linear business and get the incentives wrong. They close with a look at where platforms were heading at the time of writing, from the internet of things to finance.
What are the main lessons for founders?
- Name the one transaction. A marketplace for tutors lives or dies on one repeated exchange: a parent books a lesson and a tutor shows up. Design every feature around making that exchange easier and safer.
- Seed the hard side first. Most marketplaces have one side that is harder to attract. Recruit that side by hand, even if the work does not scale, before you spend on the easier side.
- Build trust into the product. Ratings, verified profiles, payments held in escrow and clear rules are what let strangers deal with each other. Without them, growth turns into fraud and churn.
- Charge for the right thing. Take a fee only once users get value from the connection. Charging too early or in the wrong spot pushes users to deal with each other off the platform.
- Focus on a narrow group. Platforms that try to serve every user at once spread their liquidity thin. Win one city, one niche or one use case before widening.
Who should read Modern Monopolies?
Founders planning a marketplace, booking service, community or developer ecosystem, and product leads inside larger firms who are asked to add a platform layer. It is most useful at the design stage, when you still choose which side to serve first and where to charge.
Founders selling a product directly to customers, such as a SaaS tool or a consumer brand, can skip it. The ideas help them only if they plan to open their product to third parties.

Where does Modern Monopolies fall short?
The examples date fast. Several companies held up as winners in 2016 have since stalled, and the book says little about the regulatory and labour fights that later hit ride-hailing and home-sharing apps. It also reads in places like a showcase for the authors’ consultancy. The guidance on launching a marketplace from zero is lighter than the analysis of giants that already won. The Cold Start Problem covers that early phase in much more depth, and Platform Revolution offers a broader academic treatment of the same ideas.
