The AI revolution may favor incumbents, not just startups. Large companies possess vast, proprietary datasets. If they quickly fine-tune custom LLMs with this data, they can build a formidable competitive moat that an AI startup, starting from scratch, cannot easily replicate.

As foundational AI models become commoditized, the competitive advantage is no longer raw intelligence. Lasting value comes from building a reliable ecosystem around the AI, focusing on deep workflow integration, governance, user trust, and flawless operational execution. This is the true defensible moat.

Contrary to the narrative of AI startups destroying incumbents, established enterprise software companies will likely absorb and 'domesticate' AI. They will integrate AI capabilities into their existing platforms, leveraging deep customer relationships and distribution advantages to maintain their market position.

Contrary to popular narrative, established companies hold a significant advantage over AI-native startups. Their vast proprietary data and deep, opinionated understanding of customer problems form a powerful moat. The key is successfully leveraging these assets to build unique, data-driven AI solutions, which can create a bigger advantage than a pure tech-first approach.

AI favors incumbents more than startups. While everyone builds on similar models, true network effects come from proprietary data and consumer distribution, both of which incumbents own. Startups are left with narrow problems, but high-quality incumbents are moving fast enough to capture these opportunities.

Oren Zeev argues against the narrative that AI will kill all incumbents. He believes businesses with operational complexity, deep data moats, and strong distribution are not easily disrupted. These companies are more likely to leverage AI to their advantage, while simpler software companies are at greater risk.

As AI agents require increasingly deep access to personal data, users will only grant permissions to companies they inherently trust. This gives incumbents like Apple and Google a massive advantage over startups, making brand trust, rather than technological superiority, the ultimate competitive moat.

For critical tasks like tax filing, consumers prioritize trust, brand recognition, and accountability over the potential low cost of a general AI tool. The fear of costly errors creates a durable advantage for established, specialized platforms like Intuit's TurboTax.

Contrary to early narratives, a proprietary dataset is not the primary moat for AI applications. True, lasting defensibility is built by deeply integrating into an industry's ecosystem—connecting different stakeholders, leveraging strategic partnerships, and using funding velocity to build the broadest product suite.
