Software businesses are built around the assumption that engineers are the labour. Headcount is the lever. Hiring is the bottleneck. Scaling output means scaling team size, which means scaling capital, which means scaling fundraising or bootstrapping pain.
That assumption broke in 2024–2025.
AI agents can now do most of what an engineering team does — write, review, test, deploy, monitor, iterate — when they are orchestrated by one technically literate operator who understands the system. The bottleneck is no longer hiring. It is direction.
In-Seat AI is the methodology that operationalises that shift. It is how one person runs the work of a team without the team. It is also — at a smaller scale, role by role — how one department head runs the work of two or three juniors without the juniors.
The methodology is open. Read it, build on it, take it with you. The methodology is the credential. The product Domanski.AI sells is the install — me sitting next to your operator, building the agents that fit their specific workflow, training them to own it after.
It is not a tool. It is not a stack. It is the operating system.
