DueBench · Independent verification desk

We show our work.

DueBench builds hand-verified B2B lead lists and runs business-logic-aware code audits for SaaS founders. Every deliverable arrives with its evidence attached — a source for every claim, a flag for anything we could not confirm.

Small by design. One desk, fully async, no account managers.

Engagements

Two ways to buy confidence

Method

Three gates before anything ships

Gate 1 — Sourced. Every factual claim in a deliverable needs a source we can show you. A claim without a source is cut, no matter how plausible it sounds.

Gate 2 — Live. Evidence goes stale fast: roles get filled, pages get taken down. Everything time-sensitive is re-verified on the day of delivery, not the day of research.

Gate 3 — Disclosed. Some things cannot be verified from the outside. Those ship with a flag and a note that says exactly what we could and couldn't confirm — you will never have to guess which rows are solid.

VALID
Confirmed at the source (e.g. mail server accepted the exact address)
LIVE
Re-checked on ship date — the hook, role or page is still current
CATCHALL
Domain accepts all mail; the address is format-inferred and flagged
UNVERIFIED
Could not be confirmed from outside; disclosed, never counted as verified

Verified lead lists

Quoted flat per engagement, by list size and verification depth. While we collect our first public case studies, pilot terms are deliberately generous: a free 10-account sample for a short testimonial if it proves useful.

Straight answers

What buyers usually ask

Who am I actually working with?

A small independent practice — one accountable desk, async-first. You get the person who does the work, not an account manager. Modern research tooling is part of the bench; every deliverable is verified and signed off by hand before it ships.

Do you send cold email for clients?

No, deliberately. You keep the send button, your domain reputation, and final say on every word. We deliver the verified list, the personalization, and a sequence you run yourself — with a setup SOP for warm-up, daily limits and reply triage.

Do you guarantee replies or a "safe" audit?

No. We guarantee the work is real: addresses verified or flagged, claims sourced, findings reproducible. Reply rates are quoted as industry ranges, never promises, and an audit reduces risk — it cannot certify the absence of all bugs. Anyone promising otherwise is selling you a guess.

How do we start?
