Study Notes

Network Effects Overview

  • Network effects are mechanisms where new users increase the product's value for all existing users.
  • Network effects account for 70% of tech value creation since 1994.
  • This is the strongest form of defensibility in the digital world, alongside brand, embedding, and scale.
  • 16 types of network effects are identified, ranked by strength.
  • Networks are interconnected systems of people or entities.

Network Components

  • Nodes: Participants in the network (e.g., users, customers).
  • Links: Connections between nodes.
  • Directionality: Links can be one-way (directed) or two-way (undirected).
  • Density: Ratio of links to nodes; higher density usually indicates stronger network effects.
  • Clustering: Nodes tend to group together, forming dense areas within a network.

Network Value & Growth

  • Critical Mass: Point where network value surpasses individual product value.
  • Network Size: Total number of nodes, but not the sole determinant of value.
  • Laws of Network Value: Sarnoff's Law (proportional to N), Metcalfe's Law (proportional to N^2), and Reed's Law (proportional to 2^N). Reed's Law applies to "group-forming networks" where clustering occurs.

Network Asymmetries & Irregularities

  • Networks are not uniform; they have clusters, hot spots, and dead spots.
  • Real-world factors (e.g., geography, relationships, business size) influence node behaviour and cluster formation.
  • Focus on the "white-hot center" (dense, high-activity area) to accelerate growth.

Network Types

  • Homogeneous: All nodes have the same function (e.g., telephone network).
  • Heterogeneous: Different classes of nodes with varied functions and utilities (e.g., eBay, Honeybook).

Network Effects & Value

  • One-to-one: Reciprocal, undirected connection.
  • One-to-many: Unidirectional, directed connection (e.g., Twitter).
  • Bridges: Connection between two otherwise disconnected clusters. A bridge is a link between two isolated clusters
  • Profiles: Real-world identities often lead to more effective network effects than pseudonymous profiles.

Marketplaces & Networks

  • Demand-side marketplaces: Focus on attracting buyers.
  • Supply-side marketplaces: Focus on attracting suppliers.
  • Asymmetric values: Some nodes within a side of the market are more valuable than others (e.g., premium listings on eBay).

Network Effects Types (More Detail)

  • Same-side network effects: Increase in value for the same type of user (e.g., congestion on Uber).
  • Cross-side network effects: Increase in value for a type of user due to another type of user joining (e.g., Uber drivers increasing value for riders).
  • Indirect network effects: Increase in value for one user type that benefits another type of user (e.g., more sellers on eBay benefit both sellers and buyers).
  • Negative network effects: Decrease in value due to congestion (e.g., traffic), or pollution (e.g., irrelevant information on social media feeds).
  • Asymptotic network effects: Diminishing returns after a certain network size.

Single-player vs. Multiplayer Products

  • Single-player: Value is independent of other users (e.g., using Amazon for personal purchases).
  • Multiplayer: Value is derived from interactions with other users (e.g., YouTube video views & comments).
  • Products can have both single-player and multiplayer value. Switching to multiplayer can improve the value of a product

Switching Costs & Defensibility

  • Switching costs: Costs to switch from one product to another.
  • High Switching costs: Create customer lock-in, leading to product defensibility (e.g., Apple ecosystem).

The "Chicken or Egg" Problem

  • Getting enough early users to initiate a network effect.
  • Solve this with tactics like single-player mode, compensation, or multi-tenanting.

Other Important Concepts

  • Multi-tenanting: Using multiple platforms simultaneously.
  • Disintermediation: Users bypass the platform and transact directly (a problem in marketplaces).
  • Retention: User return rate. High retention is crucial for network effects because it drives usage & thus overall value.

Additional Factors

  • Viral Effects: Getting new users to join by word-of-mouth. Viral effects can help with network effects, but don't always result in a defensible product.
  • Platform vs. Network: A common conflation due to them being similar, but understanding the distinctions is important.
  • Scale Effects: Cost reductions per unit as a company grows. These and network effects can be additive to a product's overall value and defensibility

Key Takeaway

  • Network effects are critical to building valuable and defensible technology companies in the digital age.
  • Understanding the nuances of different network types, factors influencing network value and growth and methods for mitigating negative network effects are equally important.
