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.
