What is Platform?
Platform — The organizing layer others build on — it defines what a category contains and frames everything beneath it.
A platform is a table-of-contents position: it sets the boundaries of a category and what counts as part of it. Platform names sit high in the hierarchy, which is why they frame — and capture attention from — everything built below them.
Where platform sits in the stack
In the four-layer architecture of the agentic web, platform is a Organizing (L4) concept — it defines what counts as a category. See the thesis for how the layers compound.
