The company behind PhiWebs.
PhiMajor builds PhiWebs — the world of living digital Surfaces. One AI you can review line by line, on a platform where nothing goes live unseen.
We are building the world for living digital Surfaces.
Putting something real on the web has always meant a bad trade: write code — full control, but slow and expensive — or settle for a site builder — fast, but the output is dead. PhiMajor exists to end that trade. We build PhiWebs: the place where a Surface is data, not code. Edited at runtime, versioned, and built by an AI you can actually review.
One company, one world, one engine.
Four names, one system. Here is exactly what each one means.
PhiWebs
The world where living digital Surfaces exist, evolve, and connect. The brand our customers publish on.
PWFabric
The Surface operating system underneath — catalog, contracts, runtime. PWFabric powers PhiWebs; you never see it directly.
PhiCo
Your AI partner: it builds Surfaces from a real catalog, proposes a signed Receipt — an itemized approval list of the changes — and publishes once you approve. One of the products under the PhiWebs brand.
PhiMajor
The company that builds all of it. Based in Istanbul, PhiMajor has been the signature behind these products since 2016.
Three principles that shape every decision.
Receipt before code
Every meaningful change follows a reviewable, signed plan. The discipline we ship to customers, we hold ourselves to.
Audit-ready defaults
Logs are on, versions are immutable. The data boundary between customers is enforced by architecture, not by policy.
Knowledge compounds
Every change is kept as a signed Receipt. Months later, "why is this here?" still has an answer.
