If frontier AI labs have unlimited shovels, what's stopping them from building everything?

Key Points

The article uses the “picks and shovels” analogy to argue that frontier LLM companies effectively provide the core “shovel factories” (models and token/rate access) that let developers build many kinds of applications.
It asks what limits these model providers from eventually absorbing or integrating the best startup ideas across major verticals (e.g., medical, legal, finance, education) by using large or effectively unlimited compute/token capacity.
It highlights a competitive disadvantage for startups that must pay for tokens and operate under rate limits, even when startups create better domain-specific “shovels.”
It suggests potential survival strategies—focusing on niches or tasks that are too risky or too specialized for general-purpose LLM platforms—while questioning whether those moats will erode over time.
It cites early signs of this dynamic in healthcare, where multiple vendors might be consolidated under a single LLM-driven platform, raising the question of whether patents and proprietary data are sufficient protection.

I found myself explaining AI tokens to my mom over the weekend.

At first I related them to building bricks: blocks of data the model uses to understand and respond. Then I thought about it as we're all paying for tokens as units of work. Not just a shovel, but the work a shovel can do, like horses and horsepower.

“Picks and shovels company” is the idea that a company sells the thing that is needed to do fundamental work. It comes from the California gold rush. Not everyone will find gold, but everyone looking for gold will buy picks and shovels.

Thus, AI companies' LLMs are shovel factories and AI tokens are shovels. Smart shovels. These shovels do work across writing, coding, research, planning, support, analysis, and more. And everyone is using them to build new products, even better shovels.

So if foundation model companies control the shovel factories, and they can use effectively unlimited shovels on their own ideas, what happens to everyone building on top of them?

How can startups, who have to pay for tokens and rate limits, compete against the shovel factories?

Medical, legal, compliance, education, finance. If a category gets big enough, what stops the model company from absorbing the best ideas directly into its own platform?

The solution I came up with was creating products that were incredibly niche or too risky for a general LLM company to touch. But still, everything seems like it’s on a timeline before it gets integrated into LLM platforms.

It’s already happening with the medical industry. Why would a hospital use dozens of different vendors if they can use one LLM to assist doctors with diagnosing patients, help patients navigate health plans, take care of scheduling, write contracts, and handle compliance.

You could say speed, focus, and trust might help startups, but that moat disappears when the LLM can throw unlimited shovels at the problem. Now that a small team can run a startup that once took hundreds of people, the LLM company can become a multi headed hydra, with businesses in every industry.

Are patents and proprietary data enough to protect yourself from platform risk? Can startups create a real moat for survival? Or is everything already on a clock?
