Lead list building

Lists built to your criteria, verified, and deduplicated against what you already have.

Most bought lists are stale exports somebody resold. We build yours from live sources against the filters you actually sell to, verify the addresses, and strip out everyone already in your CRM.

Why bought lists underperform

Three failures, all avoidable.

Sold many times over

A list resold to a hundred buyers has been emailed a hundred times. The good contacts unsubscribed long before it reached you.

Unverified addresses

Bounce rates above 5% damage your sending domain reputation. One bad list can put your whole outbound programme in spam folders for months.

Wrong filters

Generic industry codes and headcount bands rarely match how you actually qualify. You end up paying to email people who were never buyers.

What you get

A list you could hand straight to a sequencer.

Company, contact, role, verified email, phone where available, plus the enrichment fields your qualification actually depends on — tech stack, storefront platform, location, headcount, funding stage.

Deduplicated against a CRM export you send us, so you never pay for a contact you already own.

How we build it

Engineered, not typed by hand.

We built our own discovery and extraction pipeline for this — the same system that finds businesses, pulls contact details from their sites and verifies them before anything reaches a list.

STEP 01

Define the filter

Industry, geography, size, platform, role — the criteria you actually qualify on, not a generic segment.

STEP 02

Discover and extract

Automated discovery across directories, maps and company sites, with contact details pulled from the source rather than a resold database.

STEP 03

Verify and clean

Every address checked, risky and catch-all addresses flagged or removed, duplicates and your existing CRM contacts stripped out.

STEP 04

Deliver

CSV, Google Sheet, or pushed straight into HubSpot, Pipedrive or your sequencer.

Compliance

Where we draw the line.

Is this GDPR compliant?

We build B2B lists from publicly available business information — company addresses and role-based contacts, not personal accounts. Under GDPR and the UK equivalent, B2B outreach usually relies on legitimate interest rather than consent, but that assessment is yours to make and document as the data controller. We will not scrape personal social profiles, and we exclude jurisdictions on request. If your use case needs consent-based data, we are not the right supplier and will say so.

Do you send the emails too?

We build the sending infrastructure and the sequences if you want them. We don't operate bulk unsolicited campaigns on your behalf — the sending reputation, and the legal responsibility, should sit with you.

What bounce rate should we expect?

Under 3% on verified lists. If a list we deliver bounces above 5%, we replace the failed contacts at no cost.

Can you match our existing CRM?

Yes — send a CSV export of what you already have and we dedupe against it before delivery, so you only pay for new contacts.
