How to build a product when you don't have a team

Start with the problem, not the features. The clearest products come from a sharp description of what should exist and why — not a spec sheet. Say what you want to be true for the person using it.

Make the consequential calls early. What it is, who it's for, what it must do on day one. These are yours to decide; everything downstream hangs on them.

Then let the building happen around your decisions. The interface, the logic, the working thing — produced as one coherent piece, with you steering, not managing a team.

The result is yours to change. No lock-in, no dependency. That's the difference between renting a tool and owning a capability.
