70% of Tech Value from Network Effects

This study by NFX analyzed the value creation patterns of digital companies founded since 1994 to understand the impact of network effects on tech valuations. The key challenge addressed was quantifying how much of the technology sector's value creation stems from network effects versus other business model defensibilities like scale, brand, or embedding.

The research examined 336 companies founded between 1994-2017 that achieved billion-dollar valuations, categorizing each based on their core business model and defensibility mechanisms. The analysis compared companies with network effects at their core against those relying on other value creation methods, measuring both the percentage of companies and their aggregate market valuations.

The study found that while only 35% of billion-dollar companies had network effects at their core, these companies accounted for approximately 70% of the total value creation in tech over the 23-year period. Companies without network effects typically plateaued at $1-2B valuations, while network effect businesses demonstrated "asymmetric upside" with significantly higher valuations. Notable examples include the Big Five tech companies, Airbnb, Uber, and other platform businesses.

**Key takeaways for product managers:** Network effects represent the single most predictive factor for high-value tech companies, yet only 20% of startup business plans incorporate them. PMs should architect products to enable users to create value for other users from day one, as retrofitting network effects is extremely difficult. The research suggests network effects will become even more critical as new platforms in AI, crypto, IoT, and other emerging technologies are "born networked."
