Data Operations Agency in London

B2B Data Operations, Based in London

ClientWise is a London-based data operations agency serving B2B companies across the UK. We work with scale-ups, fintechs, and professional services firms - many of them headquartered in or around London - on CRM data quality, prospect enrichment, and ongoing data hygiene.

Being London-based matters for a specific reason: the companies we serve are here. The SaaS scale-ups around Silicon Roundabout and Shoreditch. The fintech companies in Canary Wharf and the City. The professional services firms in the Square Mile, Holborn, and Mayfair. When your data operations partner understands the UK market - not just the data tools, but the business landscape, the regulatory environment, and the way UK B2B companies actually sell - the work is better.

What We Do

CRM Quality Audit

A full audit of your CRM data: duplicates, decay, compliance gaps, and enrichment opportunities. We deliver a scored dataset and a prioritised action plan. Fixed price, 5-7 business days. For London-based teams, we offer an optional in-person walkthrough at your office to review findings with your sales and RevOps leadership.

ICP-Verified Prospect Pool

Net-new prospect lists built to your ICP, verified and enriched with UK-native data sources. Particularly relevant for London companies targeting UK mid-market and enterprise - we source from Companies House, the FCA register, trade directories, and professional body registers that global data providers typically miss.

Pipeline Retainer

Ongoing CRM maintenance: monthly enrichment, deduplication, decay monitoring, and compliance screening. Your data stays clean without your team touching it. We meet London-based clients quarterly in person to review data quality trends and adjust priorities.

London-Specific Expertise

London's B2B market has characteristics that affect data operations directly:

• High employee turnover. London's job market moves fast, particularly in tech and financial services. Contact data decays faster here than in other UK regions - a quarterly enrichment cycle that works for Leeds, Sheffield, or Bristol is often too slow for London-based target accounts.
• Regulated industries concentrated in the City. If you sell to financial services, insurance, or legal - all heavily represented in London - your data needs a compliance layer that generic providers do not offer. FCA register data, SRA records, and professional body registers are part of our standard sourcing.
• Dense competitive landscape. London companies are heavily prospected. Your outreach competes for attention with dozens of other vendors. Data quality - reaching the right person, at the right time, with relevant context - is the difference between a response and the spam folder.

In-Person Workshops

For London-based teams, we offer in-person working sessions at your office. These are particularly useful for:

• CRM Quality Audit walkthrough - reviewing findings with your sales, marketing, and RevOps leadership in the same room
• Data strategy workshops - defining your ICP, mapping your target market, and building a data operations plan
• Quarterly retainer reviews - assessing data quality trends, adjusting priorities, and planning the next quarter's data operations

We work remotely with clients across the UK, but there is value in sitting down together when the work involves cross-functional alignment. Most of our London clients take advantage of this at least once per quarter.

Pricing

CRM Quality Audits start at £2,000. Prospect Pools are scoped per project. Retainers start at £2,500 per month. In-person workshops are included for retainer clients; for standalone engagements, they are available at no additional cost for London-based teams.

Book a free scoping call - or if you prefer to meet in person first, we are happy to come to your office for an initial conversation. No obligation, no pitch deck.

Frequently Asked Questions

Where are you based in London?
We are based in central London and work with clients across the city - from Shoreditch to Canary Wharf to the West End. For in-person meetings, we come to your office.

Do you only work with London companies?
No. We work with B2B companies across the UK. London is where most of our clients are based, but the work itself is delivered remotely regardless of location. In-person workshops are a London-specific bonus, not a requirement.

Can we meet before committing?
Yes. We are happy to meet in person for an initial conversation. The scoping call is free and typically takes 15-30 minutes - enough to understand your situation and confirm whether we can help.

Do you specialise in any particular London industries?
Our strongest London client base is in SaaS, fintech, and professional services - reflecting London's business landscape. We also work with recruitment firms, media companies, and B2B agencies.

What makes you different from other London data agencies?
We are a data operations agency, not a data broker. We do not sell lists. We clean, enrich, and maintain your data as an ongoing service. The difference is accountability - we stand behind the quality of every record we deliver.
