Definition: What is a platform business model?
A platform business model (multi-sided platform) is a business model pattern in which a company provides an infrastructure that enables direct exchange between two or more user groups. The platform itself does not create or own the product, but rather enables and facilitates transactions.
The basic principle: Instead of a linear value chain (pipeline: producer → intermediary → customer), the platform creates an ecosystem in which participants interact directly with each other. Value is created through intermediation, trust-building, and network effects.
Platform business models dominate the global economy today: 7 of the 10 most valuable companies worldwide are based on platform logic (Apple, Microsoft, Amazon, Alphabet, Meta, Tencent, Alibaba).
Types of platform business models
- Marketplaces (transaction platforms): Intermediation between buyers and sellers. Examples: Amazon Marketplace, eBay, Etsy, Airbnb
- Innovation platforms: Provision of a technological foundation on which third parties build their own products. Examples: iOS/Android App Stores, Salesforce AppExchange
- Social platforms: Connecting people for communication and interaction. Examples: LinkedIn, Facebook, TikTok
- Content platforms: Connecting content creators with consumers. Examples: YouTube, Spotify, Medium
- Service platforms: Intermediation between service providers and customers. Examples: Uber, Fiverr, Upwork
- Data platforms: Aggregation and provision of data. Examples: Bloomberg, Statista
Network effects: The key to success
Network effects are the central value creation mechanism of platforms:
- Direct network effects: More users on the same side = more value (e.g., social networks: the more friends, the more valuable)
- Indirect (cross-side) network effects: More users on one side = more value for the other side (e.g., more sellers on Amazon = more choice for buyers)
- Data network effects: More users = more data = better AI algorithms = better user experience for everyone
Network effects create natural monopolies and high barriers to entry—a winner-takes-most market. This makes platforms extremely valuable, but also makes getting started particularly challenging (chicken-and-egg problem).
Revenue models of platforms
- Transaction fee: Percentage share of each intermediated transaction (Airbnb, Uber, eBay)
- Subscription: Monthly fee for access (LinkedIn Premium, Spotify Premium)
- Freemium: Free basic access, premium features for payment
- Advertising: Free service, monetized through ads (Google, Facebook, YouTube)
- Listing fees: Fee for posting offers
- Data monetization: Sale of anonymized user data and insights
Platform strategies for SMEs
SMEs can also leverage platform logic:
- Industry niche platform: Focused platform for a specific industry or region—here SMEs have advantages over generic platforms
- Community platform: Building an expert community around your core topic—monetization through membership or premium content
- Using existing platforms: Leverage Amazon, Shopify, LinkedIn as sales channels instead of building your own platform
- Becoming an ecosystem partner: As a specialized provider on established platforms (e.g., Salesforce partner, Shopify app developer)
- B2B marketplace: Industry-specific intermediation between suppliers and customers with specialization advantage
Building a platform: Step by step
- Define interaction: Which user groups are you connecting? What core interaction are you facilitating?
- Solve chicken-and-egg: Build one side first—through subsidization, own content, or partnerships
- Build trust: Rating systems, guarantees, and verification reduce transaction risks
- Activate network effects: Design features that improve with more users
- Find revenue model: Which side pays? How? When? Often: subsidize one side, monetize the other
- Scale: Accelerate platform growth through growth strategies and go-to-market

Frequently Asked Questions
What is a platform business model?
A platform business model connects two or more user groups and creates value through intermediation and network effects. The platform often owns no assets itself, but enables direct interactions between providers and consumers—like Airbnb for accommodations or Uber for mobility.
Can SMEs also build a platform business model?
Yes—especially in specialized niches. SMEs have advantages with industry-specific or regional platforms because they better understand user needs. Alternatively, SMEs can use existing platforms as sales channels or become ecosystem partners of established platforms.
What are network effects in platforms?
Network effects mean: The more users a platform has, the more valuable it becomes for everyone. Direct network effects: More users = more value (e.g., social networks). Indirect network effects: More providers = more choice for buyers and vice versa. They create a self-reinforcing growth cycle.
