A small team builds Bandzen, and the same people answer the email.
support@bandzen.com — for support, billing, refunds, or telling us something is wrong. We answer within two working days, usually sooner.
Reporting a problem with a band estimate
Every score Bandzen produces is an estimate from a model, and models get things wrong. If a report looks indefensible, send us the attempt and we will look at it — that feedback is how the rubric improves.
