Many teams wrongly focus on the latest models and frameworks. True improvement comes from classic product development: talking to users, preparing better data, optimizing workflows, and writing better prompts.

As foundational AI models become more accessible, the key to winning the market is shifting from having the most advanced model to creating the best user experience. This "age of productization" means skilled product managers who can effectively package AI capabilities are becoming as crucial as the researchers themselves.

Early-stage AI startups should resist spending heavily on fine-tuning foundational models. With base models improving so rapidly, the defensible value lies in building the application layer, workflow integrations, and enterprise-grade software that makes the AI useful, allowing the startup to ride the wave of general model improvement.

The best application-focused AI companies are born from a need to solve a hard research problem to deliver a superior user experience. This "application-pull" approach, seen in companies like Harvey (RAG) and Runway (models), creates a stronger moat than pursuing research for its own sake.

Counter to fears that foundation models will obsolete all apps, AI startups can build defensible businesses by embedding AI into unique workflows, owning the customer relationship, and creating network effects. This mirrors how top App Store apps succeeded despite Apple's platform dominance.

In the fast-moving AI sector, quarterly planning is obsolete. Leaders should adopt a weekly reassessment cadence and define "boundaries for experimentation" rather than rigid goals. This fosters unexpected discoveries that are essential for staying ahead of competitors who can leapfrog you in weeks.

To avoid being made obsolete by the next foundation model (e.g., GPT-5), entrepreneurs must build products that anticipate model evolution. This involves creating strategic "scaffolding" (unique workflows and integrations) or combining LLMs with proprietary data, like knowledge graphs, to create a defensible business.

ElevenLabs' CEO sees their cutting-edge research as a temporary advantage—a 6-12 month head start. The real, long-term defensibility comes from using that time to build a superior product layer and a robust ecosystem of integrations, workflows, and brand. This strategy accepts model commoditization and focuses on building durable value on top of the technology.

The founder of Stormy AI focuses on building a company that benefits from, rather than competes with, improving foundation models. He avoids over-optimizing for current model limitations, ensuring his business becomes stronger, not obsolete, with every new release like GPT-5. This strategy is key to building a durable AI company.
