Client voices
What teams take from a cohort reading
“The signup-week tables finally showed us that our spring onboarding change looked strong in week one and then faded by day twenty-one. Helen walked us through the caveats before we changed the roadmap. I still wish we had booked the follow-up session earlier in the quarter.”
“We had been treating day-three silence as churn. The activation study reframed it as a natural pause for our weekly content cadence, which saved us from a clumsy push notification rewrite.”
“Priya’s brief named the exact interval where tradespeople stopped opening the schedule after quiet job months. Specific enough that our support team could change the check-in script the same week.”
