A map of how businesses make money online and why digital economics — near-zero marginal cost, global reach — changes the rules.
A generation ago, starting a business meant a physical location, inventory, and a local market. Today a person with a laptop can reach customers worldwide by lunchtime. The online economy has not just moved old businesses onto the internet; it has changed the underlying economics of who can compete and how money is made.
Understanding the landscape — the main models and what makes them tick — is the foundation for everything else in this module.
Most online businesses fall into a few families: e-commerce (selling physical goods), digital products (software, courses, media), services (freelancing, consulting delivered online), advertising (free content monetised by attention), marketplaces (connecting buyers and sellers), and subscriptions (recurring access). Many businesses blend several.
Two features change everything. First, near-zero marginal cost: once a piece of software or a course exists, each additional copy costs almost nothing to deliver. Second, global reach: the internet removes geographic limits on your market. Together these allow tiny teams to serve huge audiences.
Those same features concentrate markets. When the best product can serve everyone at low cost, customers pile onto the leader, and a few winners capture most of the value while many others earn little. Digital competition is often brutal.
A designer creates a set of digital templates once and sells them online. The first sale covers the work; every sale after that is almost pure profit, and buyers can come from anywhere. But because rivals can copy the idea cheaply, the designer must keep improving and marketing to stay ahead.
Digital does not guarantee scale. A local service that depends on physical presence — a plumber, a dentist — gains a website and online booking but still serves one town at a time. Not every business enjoys near-zero marginal cost, and pretending otherwise leads to bad plans.
Shopify, founded in 2006, is a clear example of how digital tools reshaped the landscape. Its founders originally tried to sell snowboards online, found existing e-commerce software inadequate, and built their own — then sold that to other would-be merchants. By turning "open an online store" into something almost anyone could do without coding, Shopify helped millions of small sellers reach global customers. It illustrates two lessons at once: digital businesses often scale by serving other businesses, and lowering the barrier to entry can create an enormous market — while also intensifying competition among the sellers who now flood in.
List five online businesses or apps you used this week. For each, name its primary model (e-commerce, subscription, advertising, marketplace, etc.). Which look winner-take-most?
Think Like a Maester: On the internet, the cost of one more customer is tiny — but so is your rival's, so value is won on more than price.
The online economy spans e-commerce, digital products, services, advertising, marketplaces, and subscriptions. Two features — near-zero marginal cost and global reach — let small teams serve vast audiences, but they also concentrate markets into a few winners. Understanding these dynamics, as Shopify's rise shows, is the starting point for building anything durable online.
