1. Origins of the Platform Business Model
1.1 Early Beginnings: From Mainframes to Ecosystems
The platform business model has roots in the early days of computing, when companies like IBM bundled software with hardware to drive the adoption of mainframes in the 1950s and 1960s. Software was not a standalone product but a complementary tool to enhance hardware's value, as seen with GE's CNC machines, which included free software to differentiate their offerings. This bundling strategy laid the groundwork for platforms as ecosystems that connect multiple stakeholders.
In the 1980s, Microsoft's Windows operating system marked a pivotal shift. By creating a platform that enabled developers to build applications for a standardised operating system, Microsoft transformed the PC industry. Windows became a two-sided platform, connecting developers (who built apps) with users (who consumed them), creating a virtuous cycle of value creation.
This model, known as a multi-sided platform, was formalised by economists like Jean Tirole and Jean-Charles Rochet in their seminal 2003 paper, "Platform Competition in Two-Sided Markets," which defined platforms as markets that facilitate interactions between two or more distinct groups, such as buyers and sellers or developers and users.
1.2 The Rise of Software Platforms
The 1990s saw the internet amplify the platform model. Netscape's browser and Amazon's early e-commerce marketplace connected users with content and sellers with buyers, respectively. These early platforms leveraged the internet's low marginal distribution costs to scale rapidly.
Amazon, starting as a bookseller, evolved into a horizontal marketplace by the early 2000s, allowing third-party sellers to list products alongside its inventory. This marked a shift from linear value chains (where firms produce and sell directly) to platform-based ecosystems that orchestrate interactions.
1.3 Foundational Framework: Understanding Platform Types
Before exploring platform evolution, it's essential to understand the fundamental distinctions that shape platform strategy:
B2B vs B2C Platforms:
- B2B Platforms serve businesses, focusing on ROI, efficiency, and long-term relationships. They feature longer sales cycles, multiple stakeholders, and customised pricing.
- B2C Platforms target consumers, emphasising convenience, price, and emotional appeal with short sales cycles and mass-market appeal.
Vertical vs Horizontal Platforms:
- Vertical Platforms focus on specific industries, offering deep specialisation and curated solutions.
- Horizontal Platforms serve multiple industries with common solutions, enabling faster scale but facing differentiation challenges.
Platform vs Marketplace Distinction: While often used interchangeably, these models serve different purposes:
1.4 Key Success Factors from Early Platforms
HBR's "Strategies for Two-Sided Markets" (2006) by Thomas Eisenmann, Geoffrey Parker, and Marshall Van Alstyne provides a foundational framework for understanding platform success. The authors argue that platforms succeed by solving the "chicken-and-egg" problem: attracting one side (e.g., developers) to draw in the other (e.g., users).
Critical success factors include:
- Subsidies (e.g., free tools for developers)
- Network effects, where the platform's value grows as more participants join
- Strategic patience to invest in one side of the market to bootstrap growth
The $32.11 trillion B2B e-commerce market in 2025, projected to reach $36.16 trillion by 2026 (14.5% CAGR), underscores platforms economic impact. Unlike traditional businesses, optimising marginal revenue equals marginal cost, platforms leverage near-zero marginal costs, as Marshall Van Alstyne notes in his 2016 HBR article, “The Economics of Platform Businesses.”
2. Evolution of Platforms: Expansion and Scaling
2.1 The Dot-Com Era and Network Effects
The late 1990s and early 2000s saw platforms like eBay and PayPal leverage network effects to scale. eBay's marketplace thrived because more buyers attracted more sellers, and vice versa, creating a self-reinforcing loop.
PayPal, initially a payment tool for eBay, became a standalone platform by enabling secure transactions across multiple marketplaces. These platforms demonstrated the power of network effects, where the value of the platform increases exponentially with the number of users.
2.2 The Cloud and SaaS Revolution
The 2000s introduced cloud computing and Software-as-a-Service (SaaS), enabling platforms like Salesforce and AWS to scale without the constraints of physical infrastructure.
Salesforce, launched in 1999, disrupted traditional enterprise software by offering a cloud-based CRM platform. Its AppExchange, introduced in 2005, allowed third-party developers to build and sell apps, transforming Salesforce into a multi-sided platform.
AWS, launched in 2006, provided infrastructure for developers to build applications, capturing value through compute usage. These platforms lowered barriers to entry for businesses, enabling rapid scaling.
2.3 Platform Evolution Pathway
The evolution from proprietary software to dominant platforms follows a predictable pattern:
Stage 1: Proprietary Utility (Low Scalability/Closed System)
- Monolithic architecture, low interoperability
- Linear value creation, one-time license models
- Examples: IBM mainframe software, early Microsoft Word
Stage 2: Digital Scaling (High Scalability/Open System)
- Cloud-hosted or modular architecture
- Subscription or usage-based models
- Examples: Early Salesforce CRM, Dropbox, Google Maps API
Stage 3: Ecosystem Emergence (Multi-sided Value Creation)
- Early network effects, APIs/SDKs introduction
- Multi-sided user base is emerging
- Examples: Early Microsoft Windows, Salesforce AppExchange launch
Stage 4: Network Dominance (Full Platform Maturity)
- Robust APIs, strong network effects
- Diversified revenue streams, massive scalability
- Examples: Apple App Store, modern Salesforce, Amazon Marketplace
2.4 Case Study: Microsoft's Platform Transformation
Microsoft's evolution exemplifies successful platform transformation:
1980s-1990s: Windows as a developer platform 2000s: Office suite expansion and enterprise relationships 2010s: Cloud transition with Azure 2020s: Ecosystem consolidation with LinkedIn acquisition
By 2025, Microsoft's enterprise relationships span nearly every major corporation, enabling upselling of new products through established distribution networks. Key success factors include:
- Embedding switching costs through data integration
- Using APIs to extend platform reach
- Creating workflow dependencies that reinforce lock-in

4. Platform Economics
4.1 Network Effects and Economies of Scale
Platforms thrive on network effects, where value increases with user participation, fundamentally different from traditional linear business models.
Types of Network Effects:
Direct Network Effects: More users enhance value for existing users
- Example: Slack's team communication improves as more team members join
- Each additional user creates value for all existing users
Indirect Network Effects: One user group attracts another
- Example: More sellers on Amazon attract more buyers, benefiting both sides
- Creates virtuous cycles that compound over time
Data Network Effects: More users generate better data, improving the platform for everyone
- Example: Netflix's recommendation algorithm improves with more viewers
- Creates competitive moats through algorithmic advantages
4.2 Platform vs Traditional Economics
Traditional Brick-and-Mortar Economics: Traditional businesses operate on linear models where profit maximisation occurs at the intersection of marginal revenue and marginal cost:
- Fixed Capacity: Physical constraints limit output
- Predictable Costs: Revenue expansion requires proportional cost increases
- Linear Growth: Every dollar of revenue matches corresponding costs
Platform Economics Divergence: Digital platforms fundamentally rewrite economic rules
Near-Zero Marginal Costs:
- Software distribution has negligible marginal costs
- Example: Shopify incurs minimal costs to add new merchants
- Enables scale without proportional cost increases
Network Effects Over Linear Revenue:
- Platforms prioritise user acquisition over immediate profitability
- Often operate at a loss initially to build network effects
- Traditional marginal revenue = marginal cost becomes less relevant
Winner-Take-All Dynamics:
- Increasing returns to scale create market concentration
- Early leaders capture disproportionate market share
- Example: Amazon's marketplace dominance through scale advantages
4.3 Revenue Model Evolution
- Subscription Models: Predictable recurring revenue (Salesforce CRM access)
- Transaction Fees: Percentage-based revenue sharing (Amazon's 15-20% seller fees)
- Freemium Models: Free access with premium upgrades (Slack's tiered offerings)
- Infrastructure Services: Usage-based pricing (AWS compute and storage)
- Advertising Revenue: Monetising user attention and data (Google's ad platform)
4.4 Switching Costs and Platform Lock-In
Modern platforms create multiple layers of switching costs:
- Data Integration: Critical business data stored within platform ecosystems.
- Workflow Dependencies: Business processes built around platform capabilities.
- Ecosystem Reliance: Third-party integrations and customisations.
- Skill Investment: Employee training and expertise development
Example: Microsoft's Azure creates enterprise lock-in through data storage, application dependencies, and integration with Office 365, making migration costly and complex.
5. Strategic Framework: Platform Positioning and Value Creation

Note on What, Why and How of Platforms vs Marketplace
What:
- Platforms offer a broad value proposition, including services, data, and interoperability. Shopify provides e-commerce tools, payments, and apps, capturing value across the merchant lifecycle.
- Marketplaces focus on transaction efficiency, capturing value through fees. Etsy’s marketplace charges listing and transaction fees but offers limited tools beyond selling.
Why:
- Platforms exist to create ecosystems that enhance functionality, integration, and customisation. Slack’s platform integrates with tools like Google Drive, creating a communication hub.
- Marketplaces exist to enable transactions with minimal friction. Amazon’s marketplace prioritises speed and price over deep integration.
How:
- Platforms facilitate interactions across multiple stakeholders, often providing tools, infrastructure, or APIs. Salesforce’s platform enables developers to build apps, businesses to manage sales, and users to access solutions.
- Marketplaces focus on connecting buyers and sellers for transactions. eBay’s marketplace matches buyers with sellers for goods, with minimal additional tools beyond transaction facilitation.
Economic Differences:
- Platforms benefit from diverse revenue streams (subscriptions, transaction fees, ads) and deeper lock-in through integrations. Salesforce’s ecosystem creates switching costs via data and app dependencies.
- Marketplaces rely heavily on transaction fees, with lower switching costs unless supplemented by services (e.g., Amazon’s Fulfilment). Marketplaces scale faster but face risks of commoditisation.
A 2020 ScienceDirect study notes that platforms create broader ecosystems with deeper integrations, while marketplaces prioritise transaction efficiency, impacting retention and revenue models.
