You buy a list and hope for the best
Prospects researched to the client’s ICP, verified before they enter the CRM

What Clients Say
“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 ClientWise came back with 900 flagged as duplicates, 600 with outdated job titles, and 300 with no contact data at all.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.”
Sarah Chen, Kayden
Head of Revenue Operations
“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.”
James Whitfield, Reachflow
VP Sales
“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
GTM Lead
“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.”
Tom Ashworth, Clearpath
Sales Director
“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.”
Nina Okafor, Vantage Group
Chief Revenue Officer
“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.”
David Renshaw, Fynn
Head of Growth
“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.”
Laura Kim, Airo
Marketing Operations Manager
“Stopped guessing, started prioritising”
“The data quality scores were a game changer. We could finally prioritise outreach by record confidence instead of guessing.”
Marcus Bell, Trellis
SDR Team Lead
“Three projects and counting”
“Fixed-price, no contract, delivered in a week. Wish every vendor operated like this. We’ve now run three projects with them.”
Anya Petrov, Northbeam
VP Operations
“£180k pipeline from a single build”
“They found 340 net-new contacts at our target accounts that we’d completely missed. Pipeline value from that single build was £180k.”

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.
30 minutes. You’ll leave with a fixed-price SOW.
