B2B Prospect Pool Service for UK Sales Teams

We build qualified, GDPR-compliant prospect lists matched to your ICP. 300-500 enriched prospects with 400+ data points. Delivered in 7-10 business days.

Why Bought Lists Don't Work

Buying a contact list gives you volume. It does not give you pipeline.

Bought lists decay within months. Half the emails bounce. The job titles are wrong. The companies don't match your ICP. Your reps spend the first two weeks cleaning instead of calling, and by week three the list is already going stale.

A ICP-Verified Prospect Pool is different. We research, verify, and enrich 300-500 prospects matched to your Ideal Customer Profile, delivered CRM-ready with 400+ data points per company. Every record is traceable to its source. Every email is verified. Every contact is checked against Companies House, LinkedIn, and multiple enrichment providers.

You get accounts your reps can actually work - not a spreadsheet to clean.

What's Included

ICP Workshop (45 minutes)

We start with a call to define or refine your target. Company size, industry verticals, technology signals, growth stage, geography, and the job titles that matter. If you already have a documented ICP, we validate it against what we can source.

Multi-Source Research

We pull from LinkedIn, Apollo, Companies House, Google Maps, trade directories, job boards, and ads intelligence. No single database. No scraped lists. Each prospect is sourced from multiple channels and cross-referenced.

Enrichment (400+ Data Points)

Every company record gets enriched with verified email addresses, direct dial numbers, LinkedIn profiles, company financials, headcount, tech stack intelligence, recent funding rounds, and hiring signals. Every contact gets firmographic and technographic data where available.

Intelligence Layer

For the top prospects, we add context: what software they use, whether they're hiring SDRs (a signal they're investing in outbound), recent ad spend patterns, and competitive positioning notes. This is the icebreaker material your reps need to personalise the first touch.

Deliverable

A CRM-ready import file segmented by priority, with outreach-ready dossiers for top accounts and icebreaker suggestions per segment.

How We Build Your Pipeline

  1. ICP Workshop. 45-minute call. We define your target together - firmographics, technographics, buying signals, and exclusion criteria.
  2. Source. We research across 6+ data channels. Every prospect is identified from at least two independent sources before making the list.
  3. Verify. Email addresses are validated via SMTP ping. Phone numbers are format-checked. Company status is confirmed against Companies House. Dead leads never make it into the deliverable.
  4. Enrich. 400+ data points appended per company. Missing fields get filled from our enrichment stack of 16 providers.
  5. Score. Every prospect is ranked by ICP fit, data confidence, and buying signal strength. Your reps start with the highest-probability accounts.
  6. Deliver. CRM-ready file plus a 30-minute walkthrough to review the data, explain scoring decisions, and discuss outreach strategy.

Timeline: 7-10 business days for 300-500 prospects.

Data Sources

We don't rely on a single database. Every ICP-Verified Prospect Pool pulls from:

  • Companies House - UK company data, directors, financial filings, incorporation dates
  • LinkedIn and Sales Navigator - contact identification and verification
  • Apollo and Cognism - email and phone verification
  • Hunter.io - email deliverability confirmation
  • Google Maps and trade directories - local business intelligence
  • Job boards - hiring signals (SDR/AE roles indicate outbound investment)
  • Ad libraries - spend signals and competitive activity

Every record includes its sourcing trail. You know exactly where each data point came from - not "our proprietary database" with no further explanation.

Pricing

£3,000-£5,000 depending on ICP complexity and prospect volume.

Fixed scope, fixed price. No hourly billing. Payment is 100% upfront.

You own the data. It lives in your CRM, not ours. No recurring access fees. No data that disappears when a subscription ends.

Book a scoping call - we will define your ICP together and scope the build in a 30-minute conversation.

If your existing CRM data needs cleaning first, start with a CRM Quality Audit. Most teams get better results from a ICP-Verified Prospect Pool when the foundation is already clean.

Who This Is For

  • Scale-ups launching or scaling outbound for the first time
  • Teams entering a new market segment, vertical, or geography
  • Post-funding companies ramping GTM and need pipeline in weeks, not months
  • Sales leaders who need accounts for new SDR hires on day one
  • Anyone tired of buying contact lists that are outdated before the ink dries

Frequently Asked Questions

Can you match our existing ICP?
Yes. We start with a 45-minute workshop to define or refine it together. If you already have documentation, we validate and build from that.

What format is the deliverable?
CSV formatted for direct import into HubSpot, Salesforce, or Pipedrive. Custom field mapping is included. Other CRM formats available on request.

Do you write outreach copy?
Not included in the ICP-Verified Prospect Pool. We provide icebreaker suggestions per segment and enough context per prospect to personalise the first touch. If you need copy, we can recommend partners.

Can we request more than 500 prospects?
Yes. Larger builds are scoped and priced on the call. Turnaround extends to 10-14 business days for 500+ prospects.

Is the data GDPR compliant?
Yes. All prospects are sourced under legitimate interest, screened against TPS/CTPS, and delivered with full sourcing documentation.

What if we want fresh prospects every month?
That is our Pipeline Retainer - 200-400 net-new enriched prospects delivered monthly, plus ongoing CRM hygiene.
