The pursuit of network effects can be a double-edged sword for businesses. On one hand, it can create a self-reinforcing cycle of growth, where more users attract even more users. However, this relentless focus on network effects can lead companies to sacrifice profitability in the process. By subsidizing user acquisition and retention, firms may inadvertently create a false narrative of success, where user growth is mistaken for genuine value creation.

The mechanism behind this phenomenon is rooted in the way network effects are typically measured and incentivized. For instance, a company like eBay, which relies heavily on network effects to drive its business, may prioritize user growth over revenue per user. In a hypothetical scenario, a 10-person team at a startup might focus on increasing their user base by 20% each quarter, even if it means operating at a loss. This approach can create a temporary illusion of success, but ultimately, it may not be sustainable in the long term.

The twist is that prioritizing network effects over profitability can have unintended consequences, such as attracting low-value users who do not contribute significantly to revenue. This can lead to a situation where the company is forced to continually subsidize these users, creating a vicious cycle of unprofitability. Furthermore, the focus on network effects can also distract from other critical aspects of the business, such as product development and customer support, ultimately eroding the company's competitive advantage.
