Why No Company Will Win the AI War: The "Rebel Alliance" Thesis | Nick Grossman

The AI industry is evolving into a massive, decentralized ecosystem rather than a monopoly dominated by a few large labs, a thesis Nick Grossman, General Partner at Union Square Ventures, calls the "Rebel Alliance." This shift is driven by the rise of the "agentic stack," where specialized agents serve as both consumer interfaces and infrastructure. Instead of relying on a single model, companies are increasingly using sophisticated orchestration to mix general-purpose and specialized models, optimizing for both cost and performance. While big labs provide foundational innovation, significant value will accrue to the application layer, where domain-specific expertise and real-world connectivity create defensibility. As agents gain autonomy in tasks ranging from coding to financial trading, the future of computing will be defined by a multi-agent fabric rather than a consolidation of power into one or two monolithic applications.
