The advantage from data network effects only materializes at immense scale. The difference between a startup with 3 customers and one with 4 is negligible. This means early-stage companies cannot rely on a data moat to win; the moat only becomes visible after a market leader is established.

In a security marketplace, customers don't *want* to find the "product" (vulnerabilities), creating a negative feedback loop unlike eBay. Bug Crowd's founder realized the moat couldn't just be network effects; it had to be the proprietary data used to match the right hackers to the right problems, maximizing success for both sides.

As AI and better tools commoditize software creation, traditional technology moats are shrinking. The new defensible advantages are forms of liquidity: aggregated data, marketplace activity, or social interactions. These network effects are harder for competitors to replicate than code or features.

Since LLMs are commodities, sustainable competitive advantage in AI comes from leveraging proprietary data and unique business processes that competitors cannot replicate. Companies must focus on building AI that understands their specific "secret sauce."

As AI models become commoditized, the ultimate defensibility comes from exclusive access to a unique dataset. A startup with a slightly inferior model but a comprehensive, proprietary dataset (e.g., all legal records) will beat a superior, general-purpose model for specialized tasks, creating a powerful long-term advantage.

The vague concept of a 'data network effect' is now a real defensibility strategy in AI. The key is having a *live*, constantly updating proprietary dataset (e.g., real-time health data). This allows a commodity model to deliver superior results compared to a state-of-the-art model without access to that live data.

The long-theorized "data network effect" is now a powerful reality in the age of AI. Access to a proprietary and, most importantly, *live* data stream creates a significant moat. A commodity AI model trained on this unique, dynamic data can outperform a state-of-the-art model that lacks it.

As AI's bottleneck shifts from compute to data, the key advantage becomes low-cost data collection. Industrial incumbents have a built-in moat by sourcing messy, multimodal data from existing operations—a feat startups cannot replicate without paying a steep marginal cost for each data point.

CEO Srini Rawl explains that while many companies focused on structured healthcare data, Datycs targeted complex, unstructured documents. This challenging niche became their competitive advantage, creating a significant data and experience moat after processing over 15 million clinical charts.
