B2B DATABASE CONSTRUCTION

Stop buying lists.
Start building databases.

Generic data purchases waste budget and pollute your CRM with names that never fit your market. We construct a bespoke contact database from scratch — researched, verified and matched to your exact ideal customer profile, one record at a time.

Custom Construction

Built to your ICP, not pulled off a shelf.

A purchased list is somebody else's definition of your market. We build differently — researching, sourcing and manually verifying every contact against your ideal customer profile before a single record reaches your CRM.

Our research team works across sixty-plus first- and third-party sources, cross-checking company sites, professional networks and proprietary databases so every record is current, accurate and genuinely relevant to how you sell.

Multi-Layer Targeting

Six filters. One precise universe.

A database is only as valuable as its targeting precision. Every build narrows through the same layered filter stack before a contact qualifies for delivery.

01

Industry & sub-vertical

Sector and niche-level segmentation across your total addressable market

02

Job title & seniority

C-suite, VP, director and manager-level contacts, not gatekeepers

03

Company size & revenue band

Headcount, ARR and employee growth signals matched to your fit

04

Geography & territory

Country, region, city and sales-territory mapping

05

Technology stack

Accounts running specific platforms, integrations or competitors

06

Buying signals & intent

Companies showing active research behaviour in your category

Human-Verified Records

Every contact, checked before delivery.

Automated scraping alone produces unacceptable error rates. Every record in your build passes a two-stage human check — role, deliverability and company match — before it ships.

Why It Matters

Bad source data is your biggest hidden leak.

Before an outreach campaign even begins, the quality of your prospecting database already determines how much of your sales capacity gets wasted.

Low lead quality is the top pain point. Most businesses trace their biggest pipeline problem straight back to poor source data.
A quarter of your list decays in months. A database purchased two quarters ago already has a meaningful share of invalid records.
Reps become researchers. Given unverified lists, sales teams spend up to a third of their time validating contacts instead of selling.
Verified, ICP-matched data pays for itself. Teams using it report meaningfully higher deliverability and lower cost per qualified meeting.
