About Stage

Helping teams see, not imagine

Stage is a simulation layer that lets product and design teams preview site changes without touching production data or waiting on engineering.

Our Mission

Product teams at enterprise companies face a frustrating reality: they can't see how their site would look with different data without asking engineering to make changes. Want to preview 12 lipstick shades instead of 6? Update a promotional badge? Test an out-of-stock flow? Get in line.

We built Stage so teams can simulate these scenarios themselves. It sits between your frontend and downstream APIs — intercepting responses and applying overrides without touching production data. Think of it as Figma for live websites.

Our mission is to give product managers and designers the power to see their ideas on real sites, instantly — no engineering queue, no risky deploys, no corrupted data.

Our Values

These principles guide everything we do—from how we build our product to how we support our customers.

Empower Non-Engineers

PMs and designers shouldn't need to file tickets to preview ideas. We put control in their hands.

Zero Risk

Simulations are read-only. Your production data, staging environments, and systems of record stay untouched.

See, Don't Imagine

Screenshots and mocks aren't enough. Teams need to see real scenarios on real sites.

Enterprise Ready

Built for large commerce and content-heavy sites. Secure, scalable, and works with your existing stack.
