Most current AI tools for sales are general large language models with a thin layer of data on top. The real productivity leap will come from future tools where deep, domain-specific knowledge—like complex enterprise sales methodologies—is embedded from the ground up.

While horizontal chatbots handle general tasks well, they fail at the highly specific, high-stakes workflows of professionals like investment bankers. Startups can build defensible businesses by creating opinionated products that master the final 1-2% of a use case, which provides significant value and is too niche for large AI labs to pursue.

As AI handles the complexities of coding, the key differentiator for new startups will shift from technical ability to deep domain knowledge. Martin Shkreli argues that experts from industries like oil and finance can now directly build solutions for problems they understand intimately, without needing a programming background.

AI performs poorly in areas where expertise is based on unwritten 'taste' or intuition rather than documented knowledge. If the correct approach doesn't exist in training data or isn't explicitly provided by human trainers, models will inevitably struggle with that particular problem.

For entrepreneurs building on top of large language models, the key differentiator is not creating general platforms but achieving deep domain specialization. The call to arms is to know a vertical better than anyone and imbue that unique knowledge into AI agents, creating a defensible moat against more generalized tools.

As AI capabilities become commoditized, the key to superior output is the user's domain expertise. An expert with precise vocabulary can guide an AI to produce better results in one attempt than a novice can in many, because they can articulate the desired outcome more effectively.

While the "bitter lesson" suggests powerful general models will dominate, vertical AI solutions can thrive by deeply integrating with a company's specific data, workflows, and project context. The model can't know this proprietary information; value is created by the application that bridges this gap.

AI can accelerate development, marketing, and sales tasks. However, it currently lacks the strategic judgment, customer empathy, and "taste" required for strong product management—deciding what to build and why.

AI coding tools struggle to replace entrenched niche software because AI lacks access to private client data and cannot provide the liability and support needed for mission-critical operations. The software's cost is often trivial compared to the operational risk of replacing it.
