What changes when someone actually owns your client’s data?

When we do

vs. when nobody owns the data

You onboard a client and inherit a CRM full of dead contacts

We audit and enrich it before your first campaign touches it

Your team spends campaign week cleaning data instead of running it

Data arrives campaign-ready. Your team stays on strategy

You buy a list and hope for the best

Prospects researched to the client’s ICP, verified before they enter the CRM

Bounce rates climb because nobody’s monitoring for job changes

Monthly monitoring catches moves before your sequences fire

The client asks “how accurate is our data?” and you don’t have an answer

You hand them a data health score. Updated monthly

“Who’s actually looking after the data?”

We are.

We audit, deduplicate, enrich, and score your client’s CRM across 16 verified sources — so you know exactly what’s broken before your next campaign fires.

  • Cleaned, deduplicated CRM export in your client’s existing field structure
  • Data health report (pre- vs post-enrichment metrics)
  • Enrichment log: source, confidence level, and change made per field
  • Suppression list with reason codes
  • Quality score (0–100) per record

ICP-Verified Prospect Pool

Prospect research matched to your client’s ICP and verified across 16 sources — delivered ready to sequence, not scraped from a shared database.

  • Verified prospect file (CSV or CRM-native): name, verified email, direct dial, job title, seniority, company context, LinkedIn URL
  • ICP match rationale per record
  • Source log per contact
  • Confidence rating (High / Medium) — no Low-confidence records delivered
  • Deliverability validation report

Email list validation, domain health monitoring, and bounce-risk scoring — so your client’s sender reputation stays protected at scale.

  • Validated list with per-record risk scores
  • Domain health report (reputation, blacklist status, spam signals)
  • Quarantined records list with reason codes
  • Monthly monitoring dashboard (retainer clients)
  • Remediation recommendations per flagged segment

Always-Fresh Pipeline Retainer

Monthly enrichment, job-change monitoring, and fresh prospect delivery — so your client’s pipeline never goes stale.

  • Monthly change-flag report with recommended action per record
  • Updated records (re-enriched, ready to replace in CRM)
  • Net-new prospect file (50/100/150 depending on tier)
  • Suppression list additions with reason codes
  • Running data health score
  • Quarterly data decay analysis

We become your invisible data team. You resell clean, enriched pipeline under your own brand — we handle sourcing, QA, and deliverability at scale.

  • White-labeled data deliverables per client
  • SLA-backed turnaround on all work
  • Dedicated Slack/comms channel
  • Per-client cost attribution dashboard
  • Cross-client deduplication reports
  • Monthly partnership review

What Clients Say

Kayden

Reply rate doubled in one month

We exported 4,200 records before the audit. ClientWise came back with 900 flagged as duplicates, 600 with outdated job titles, and 300 with no contact data at all. After importing the cleaned file, our outbound reply rate went from 2.8% to 6.1% within a month. The health report also made it very easy to explain to the board why our numbers had been soft.

Head of Revenue Operations

Reachflow

Forecast variance dropped from 35% to under 12%

We’d been putting off a CRM cleanup for two years. The scoping call took 25 minutes, SOW landed that afternoon, and the cleaned export was back in our CRM within a week. Pipeline accuracy improved immediately — our forecast variance dropped from 35% to under 12%. Wish we’d done it sooner.

Stackline

Replaced two tools and a part-time hire

The monthly data ops retainer replaced two tools and a part-time hire. Our CRM hasn’t been this clean since the day we set it up.

Priya Sharma, Stackline

Clearpath

Conversion rate jumped 22%

We had 6,000 contacts and no idea which ones were still valid. ClientWise flagged 2,100 job changes we’d missed. Conversion rate jumped 22% the next quarter.

Full sourcing transparency for the board

Every record came with a sourcing trail. First time I’ve been able to tell our board exactly where our pipeline data comes from.

Beat every other data provider on UK accuracy

We tried ZoomInfo, Apollo, Lusha. None of them got UK data right. ClientWise nailed Companies House matching on the first pass.

Messy export to clean database in five days

Handed them a messy HubSpot export on Monday. Got back a fully deduplicated, enriched database by Friday. No onboarding, no kickoff meetings.

Stopped guessing, started prioritising

The data quality scores were a game changer. We could finally prioritise outreach by record confidence instead of guessing.

Fixed-price, no contract, delivered in a week. Wish every vendor operated like this. We’ve now run three projects with them.

Frequently Asked Questions

For a CRM audit, a CSV export of your client’s records — whatever fields they have. For an ICP-Verified Prospect Pool, the ICP: target industries, company size, geographies, and job titles. The scoping call covers all of this in 30 minutes.

Most projects deliver within 5–10 business days. CRM Quality Audit on 2,000 records: 5–7 days. ICP-Verified Prospect Pool of 500 prospects: 7–10 days. Pipeline Retainer engagements run on a monthly cycle with a fixed delivery date.

Yes. The reports, exports, and enrichment logs are yours to present to your client however you like. We don’t appear anywhere in the output unless you want us to.

Absolutely. A CRM audit on a subset (500–1,000 records) is a sensible starting point to see the process and output quality before committing to a larger engagement. Scope it on the call.

We deliver to HubSpot, Salesforce, Pipedrive, and most other CRMs via CSV import. For HubSpot and Salesforce we format the export for their native import flows.

Every project includes a review round. If the data doesn’t meet the agreed quality benchmarks, we fix it. If we genuinely can’t deliver what was scoped, we refund the relevant portion. The terms are in every SOW.

Your next outreach campaign deserves better data.

If the data is wrong, everything downstream suffers — the targeting, the sequences, the client’s confidence in your agency. One conversation sorts it.
