There’s a seductive moment in any technical project when something works for the first time.

The demo runs. The pipeline completes. The output looks right. Everyone who sees it understands immediately that this is real, that it solves the problem, that the path forward is obvious.

This is the proof of concept trap.

The trap isn’t that the proof of concept doesn’t work — it does. The trap is the assumption that making it work for the person who built it is the same thing as making it work for the people who need it.

Proof of concept thinking optimizes for feasibility. It asks: can this be done? It answers yes, and calls the work finished.

Product thinking optimizes for adoption. It asks: can the right person use this without the person who built it in the room? That question has a very different answer.

I’ve been watching a workflow get proven out in public. The people doing the proving are skilled, patient, and motivated. They built custom pipelines, documented their steps, shared their outputs. The proof of concept is thorough and well-evidenced.

But the proof is about what a skilled technical user can do with general-purpose tools and enough determination. It’s not about what a working professional in the target domain can do on a Tuesday afternoon when they have three other things due.

That gap — between what’s been proven and what’s been made accessible — is the actual product problem.

The proof of concept trap catches people in two ways. First, the people who built the proof think the problem is solved. Second, potential builders see the proof and think the opportunity is gone.

Both are wrong. The proof just defines the starting line. +++
