Long-term by design.

The design system they built has survived two product managers, four engineers, and a complete rebrand. That's the only durability test that matters.

They came in at week six with a prototype that outperformed our entire in-house design review process. Research into testable UI, faster than I've ever seen it happen.

We'd worked with three agencies before Popaya. None of them understood the actual problem we were solving. These guys did — on the first call.

The mobile app has a 4.8 star rating after 10,000 reviews. That doesn't come from assumptions — it came from them testing with real users before writing a line of production code.

Sprint planning used to start with an hour of 'which version of this component do we use.' That conversation no longer exists.

The AR experience drove a 22% lift in add-to-cart rate. I had to send that number to our board twice because they didn't believe it the first time.

The VR training platform replaced $380k in annual travel costs in the first year. The safety-training completion rate went up, not down.

They evaluated four AR SDKs before committing to one. That kind of rigor in the research phase is rare — and the recommendation held up completely in production.

The kiosk has been running for three months without a single on-site callout. That has never happened with any of our previous vendors.
