In their words
What engineers say when the sales call is over.
“We used to close API support tickets with an apology. Now we close them with a wake ID and the exact line of the payload that was wrong. Average time to resolution went from four days to under an hour.”
Iris CalderStaff engineer, Northbank Payments “The consumer view is the part nobody else ships. Seeing our p95 split by integration told us in an afternoon what six months of service dashboards had not.”
Devan RouxHead of platform, Halyard Retail “Replay paid for the whole contract. We caught a settlement regression in staging by replaying eleven thousand production requests against the release candidate.”
