Porter's Five Forces framework analyses the industry environment to assess how attractive (profitable) an industry is to operate in. Higher force intensity = less attractive industry.
1. Threat of New Entrants
How easy is it for new companies to enter the market? Barriers include capital requirements, brand loyalty, regulatory hurdles, technology complexity, and network effects.

1. Threat of New Entrants
How easy is it for new companies to enter the market? Barriers include capital requirements, brand loyalty, regulatory hurdles, technology complexity, and network effects.
Duolingo: MODERATE — low barriers for basic apps, but Duolingo's brand, gamification IP, and user data create significant barriers to matching their quality.2. Bargaining Power of Suppliers
How much leverage do suppliers have over the industry?
Duolingo: LOW — Duolingo creates most of its own content; doesn't depend on external content suppliers.3. Bargaining Power of Buyers (Customers)
How much leverage do customers have? Buyer power increases when:
Buyers purchase in large volumes (concentration gives negotiating leverage)Many substitutes exist (low switching costs)Price transparency is high (easy comparison shopping)Food delivery: Zomato and Swiggy act as "buyers" of restaurant services. With millions of users, they have leverage to negotiate lower commissions from restaurants who depend on the platform for orders.4. Threat of Substitutes
The risk of customers choosing a completely different type of product to solve the same problem.
Duolingo: HIGH — YouTube tutorials, AI chatbots, MOOCs, traditional tutors all help users learn languages without Duolingo. They are substitutes, not direct competitors. High substitution threat limits pricing power.5. Rivalry Among Existing Competitors
The intensity of competition within the industry. When competitors adopt superior technology (e.g., generative AI for customer support while you use rule-based chatbots), this intensifies rivalry.
PESTLE-to-Porter Connection: If PESTLE's Technological factor reveals that generative AI can automate customer support at 10x lower cost, the force most directly affected is Threat of Substitutes — AI tools are substitutes for human support services.
