Compare each customer only to themselves.
The method begins with a simple, demanding idea: compare each customer only to themselves. Before the product has had time to do anything, we capture where that person starts. Every later check-in is read against that personal starting point, so the change we report is change within that individual, not an average pulled from a crowd of strangers who began in different places. Comparing a person to themselves removes the largest source of noise in most consumer measurement, the fact that no two people start alike.
Consistency is the rigor.
Rigor lives in consistency. Each customer answers the same structured measures, in the same form, at each check-in, beginning with a clean baseline taken before first use. That consistency is what lets a change be read as a change, rather than an artifact of asking different questions at different moments.
No number arrives bare.
Each read is reported with a stated confidence level that reflects how many customers it draws on, how consistent the signal is, and how much time has passed. An early, thin read is labeled as exactly that. A firm one is too. As more customers move through their first weeks, confidence rises and the picture settles. You are never asked to trust a number more than the data behind it earns.
The honest curve is the product.
Choose the rung your claim needs.
Measurement comes in rungs, and you choose the one your claim needs.
Within-person baseline read
Reads how your customers respond against their own baseline: their reported experience, the timing, the subgroups, the patterns. It establishes how your customers responded and what they reported feeling, measured honestly and labeled by confidence.
Experience and perceptionClaims-Ready
When a claim needs to separate your product's effect from everything else at work in real life, that calls for a higher rung. The Claims-Ready rung adds an independent review board and a control group, the design built for study-grade claims. Same honest posture, more rigorous instrument, for when the claim you want to make asks for it.
Study-grade claimsRigor you can inspect.
The measures, the method, and the way confidence is assigned are documented and open to inspection. Before you stand behind a number, you can see how it was produced. Rigor you cannot inspect is just a claim. Rigor you can is the reason to trust the read.
Your claims, our measurement.
Your product claims stay in your voice. The measurement stays in ours. That separation is what lets the read work as honest evidence rather than as marketing the brand wrote about itself. See the two voices side by side.
