"Layering Network Effects: Strengthening Defensibility and Scalability"

Introduction:
Network effects have proven to be a powerful force in the success of many businesses. By connecting users and creating value through network interactions, companies like Slack, Carta, and Poshmark have achieved significant advantages in terms of defensibility and scalability. However, these network effect models can be further enhanced by layering multiple forms of network effects on top of each other. In this article, we will explore two approaches that entrepreneurs can take to effectively layer network effects, and how this can strengthen their businesses.

Adding New Types of Network Participants:
The first approach to layering network effects is by introducing a new type of network participant and connecting them to existing users. This was demonstrated by Slack when they created a developer program and app directory in 2015. By allowing third-party developers to create integrations for Slack users, they added a user-developer network effect on top of the existing user-user network effect. This not only increased the value proposition for customers but also increased switching costs, making it harder for users to switch to a competing platform.

Amazon also utilized this approach by adding third-party sellers to their marketplace, layering a marketplace network effect on top of their existing data network. This not only created a new business for Amazon but also protected them from the downsides of relying solely on data network effects. It is important to note that companies can add multiple types of participants to successively layer new network effects, as demonstrated by Shopify.

Creating New Types of Connections between Existing Network Participants:
Another approach to layering network effects is by creating new connections between existing network participants. AngelList, for example, started as an interaction network connecting investors and entrepreneurs. In 2013, they launched syndicates, which connected investors and entrepreneurs in a marketplace for raising funds. This not only added a new network effect but also provided a SaaS workflow for managing the fundraising process. This approach requires a deeper understanding of customer behavior but is easier to execute as it does not involve acquiring new participants.

Combining Both Approaches:
Both approaches can be combined, as demonstrated by Poshmark. They initially started as a social, C2C commerce app that allowed users to buy and sell clothes. They added a social layer by allowing users to communicate and follow each other on a social feed, connecting all users on an interaction network. In 2015, Poshmark launched a wholesale portal that allowed sellers to buy clothes directly from brands, layering a new B2C(2C) marketplace on top of their product. This combination created a sticky experience where users not only came to buy or sell clothes but also to discover new brands and styling ideas.

Actionable Advice:

1. Identify opportunities to add new types of network participants to your business model. Consider how these participants can enable new types of interactions or transactions that enhance the value proposition for your customers.
2. Look for ways to create new connections between existing network participants. Understand your customers' behavior and find ways to facilitate interactions that provide additional value.
3. Consider combining both approaches to maximize the strength of your network effects. By layering multiple forms of network effects, you can create a more robust and defensible business.

Conclusion:
Layering network effects is a powerful strategy for multiplying unfair advantages in today's competitive business landscape. By adding new types of network participants and creating new connections between existing participants, companies can strengthen both defensibility and scalability. However, it is important to carefully consider the implementation and execution of these strategies to ensure success. By following the actionable advice provided, entrepreneurs can leverage the power of network effects to drive their businesses forward and achieve long-term success.
