Definition

Measurement Portability is the right and technical capability to reuse fit data across operators without re-entry, loss, or lock-in.

It means not repeating the same measurements every time a new tailor, brand, or stylist enters the relationship.

Investor meaning

Portability is the wedge that turns fragmented tailoring data into a network layer with interoperability potential.

Why it matters

It reframes fit as customer-owned infrastructure rather than operator-owned residue from a transaction.

Concept FAQ

Direct answers for search, AI, and investor questions.

Is portability only about export?+

No. Export is one expression. Portability also means shared interpretation, permissions, and continuity across approved operators.

Why is portability a category-level idea?+

Because it changes who owns the data relationship and makes the platform useful across multiple brands instead of inside a single stack.
