Bids, proposals, a study you're scoping, or a question you'd rather ask a human than a form.
The more you can tell us, the more useful our first reply will be — but none of it is required beyond a way to reach you.
Occasional notes on research practice and data quality. Nothing else, and you confirm by email first.
A senior person reads it — not a queue. If we're the right team for the work you'll get real questions back, and if we're not, you'll hear that just as quickly.
Reply to whoever you've been dealing with — the same person stays on your study from the first email through delivery.
