Your CRM is lying to you. We fix that.

We clean, verify and enrich B2B data so your sales team stops chasing dead contacts. In one recent audit we found 51.4% of a client’s database was unusable — before it damaged their sender reputation.

The problem

B2B data decays at 25% a year. Most teams don’t notice until the bounces start.

Contacts change jobs. Domains lapse. Mailboxes close. Duplicates multiply every time someone imports a list. By the time your open rates drop, your sender reputation is already damaged — and rebuilding that takes months.

Bounce rates climbing

Above 3% and your domain reputation is at risk. Above 10% and email providers start throttling you — including the mail people actually want.

The same company, five times

“Acme Corp”, “ACME Corporation”, “acme corp.” — three records, one customer, three conflicting histories and nobody sure which to trust.

Nobody trusts the dashboard

When the sales team keeps a private spreadsheet instead of using the CRM, the CRM has already lost — and so has every report built on it.

Case study · Automotive B2B services

We found 51.4% of their database was unusable

Their outbound was failing — high bounce rates, poor engagement, and a sender reputation heading toward blacklisting. The sales team was spending roughly half its outbound hours on contacts that no longer existed.

The four-layer hygiene audit

  1. Syntax & DNS validation — malformed addresses and dead mail servers, removed before they cost you anything.
  2. SMTP handshake — real-time mailbox verification without sending a single email. No risk to your sender reputation during the audit itself.
  3. Heuristic decay analysis — job and company changes estimated at 98%+ accuracy.
  4. CRM-readiness formatting — every surviving record standardised to your destination platform’s structure.

“B2B data decays at an annual rate of 25%. We don’t just provide leads — we make sure your CRM stays a working engine rather than an archive of people who used to work there.”

Why teams stay

Four reasons clients come back

The Bounce-Back Guarantee

If any email address we deliver bounces, report it within 5 days and we replace it free. We can offer that because every address is verified through ZeroBounce before it reaches you.

A team, not a bottleneck

Ten data specialists means your 6,000-row cleanup doesn’t sit in a queue. We cleaned a 6,000-record Capsule CRM — six years out of date — ahead of schedule.

Regulated-industry experience

Financial services, healthcare and public sector. We built a verified contact list covering all 58 California counties — delivered in full on the first attempt with zero revisions.

We tell you when we’re running late

“Smooth and honest communication about the timeline was very much appreciated.” — a client in Japan. We’d rather tell you early than surprise you late.
