About ClientWise

Your reps should sell, not clean data

We’re the UK data ops team behind clean CRMs, verified pipeline, and records your reps actually trust. Not a tool. Not a database. A team that does the work.

We don’t sell software. We don’t run outreach. We don’t resell data. We do one thing — make sure your GTM team is working with data they can trust.

You have integrations. Your reps have browser extensions. There are a hundred enrichment vendors promising 98% accuracy. And yet Monday’s pipeline review still shows contacts with no phone, no title, and no proof anyone verified them. Ever.

That’s not a tool problem. It’s an operations problem. Someone has to audit every record, cross-reference it across sources, verify it against Companies House, and do it again next month. We’re that someone.

40% of CRM data goes bad within 12 months

People change jobs. Companies fold. Numbers go dead. Every month you wait, your reps dial voicemail, email ghosts, and wonder why reply rates keep dropping. The cost isn’t the tools you’re paying for — it’s the pipeline you’re not building.

Our Story

Built from the frustration of bad data

We kept watching the same thing happen: SDRs deduplicating by hand. Ops leads Googling to check if someone still worked somewhere. Managers buying lists that were stale the day they arrived. Hours burned every week on work that nobody was hired to do.

So we built a team around doing it right. Analysts who cross-reference 16 sources per record, verify against Companies House, and deliver data with a full sourcing trail your compliance team can audit.

Who We Serve

UK B2B teams who need results

How We Operate

Four principles that shape every engagement.

Humans, Not Algorithms

A person researches every record — not a scraper, not a probabilistic match. You get a named analyst who knows your market, not a dashboard that guesses.

Full Sourcing Trail

Every data point ships with its source, verification date, and confidence score. When your compliance team asks where the data came from, you have the answer.

Fixed Scope, Fixed Price

You know exactly what you’ll get and what it costs before we start. If it doesn’t meet benchmarks, we fix it at our cost.

GDPR-Native Operations

Built under UK GDPR from day one. Verified against Companies House. We don’t retain your data after delivery and never resell it.

Quality Guarantee

Every project includes a review round. If data falls below agreed benchmarks, we fix it — no argument, no extra charge. Can’t deliver what was scoped? We refund. No annual contracts. No opaque pricing.
