Most store changes ship on faith
A redesign goes live and the only evidence it worked is that nobody complained. Agencies bill for the pages, not for the result; themes make every change slow enough that nobody dares to test twice.
Proa exists to close that gap: every change is reversible, previewed on the real store, and measured in orders and revenue against the version it replaced.
How Proa works
Design on-brand
Studio learns your store's identity from your live site or your Figma, then generates brand-faithful sections and pages, ready for your Shopify theme.
Ship without fear
The Proa Runtime script delivers every change to your storefront in seconds, with a real-store preview before anything goes live and instant rollback at any time.
Measure what matters
Every variant is measured against the original with per-order revenue attribution. Decisions come from the register, not from hunches.

An agency-built product
Proa comes from Vasta, an agency with more than ten years designing, building, and optimizing online stores, 400+ Shopify entrepreneurs served along the way.
The product grew out of that practice. Year after year, the same needs kept coming back: pages that respect the brand, changes that go live without fear, and an honest answer to whether each one paid off. Proa is that experience turned into software, the work we refined by hand for a decade, now on your store.
