Start Free — 30 CreditsThe Problem
A B2B database is only as valuable as the depth and freshness of its records. Most purchased or organically-grown databases have a thin-data problem: they contain names and emails but lack the firmographic and technographic context that enables effective targeting. Without enrichment, segmentation is limited to basic geography and industry — which means your SDRs are treating a 5-person startup the same as a 500-person scale-up.
How Cleanlist Solves This
Cleanlist enriches your entire B2B database at the contact and company level simultaneously. Contact records gain verified emails, direct dials, current job titles, and social profiles. Company records gain employee count, revenue range, industry classification, tech stack, funding history, and HQ location. The waterfall approach ensures each data point comes from the most accurate provider for that specific segment.
Firmographic Enrichment Improves Lead Scoring Accuracy by 47%
TOPO Research (now Gartner) found that lead scoring models using only behavioral signals (website visits, email opens, content downloads) correctly predicted sales-readiness 38% of the time. When firmographic data — employee count, revenue, industry, and funding stage — was added to the model, accuracy jumped to 56%, a 47% improvement. The reason is that behavioral signals indicate interest but not fit. A 3-person startup downloading your enterprise pricing guide shows high intent but zero fit; a 500-person company in your target vertical visiting your homepage once shows modest intent but excellent fit. Combining both dimensions produces dramatically better qualification. Cleanlist's database enrichment adds the firmographic layer that most scoring models lack. Customers who rebuilt their lead scoring after enriching their database reported 31% fewer unqualified leads passed to sales and 19% shorter sales cycles on qualified opportunities.

How It Works
Upload or Connect Your Database
Import your database as CSV (up to 1M records per file), connect via CRM integration, or push records through the REST API. Cleanlist handles any schema — auto-mapping columns to enrichment fields.
Database Health Assessment
Before enrichment, Cleanlist analyzes your database: total records, fill rates by field, data age distribution, duplicate prevalence, and estimated enrichment coverage. This assessment is free and uses no credits.
Enrichment Configuration
Select which fields to enrich across contact and company levels. Toggle individual data categories: contact details, firmographics, technographics, social profiles, and funding data. Budget controls let you set a maximum credit spend.
Waterfall Enrichment at Scale
Cleanlist processes records in optimized batches, routing each to the providers with the highest expected match rate based on industry, geography, and company size. Progress tracking shows real-time fill rates and match percentages.
Data Reconciliation
Enriched data is reconciled against your existing records: new fields are appended, outdated fields are flagged for update, and conflicting data points are surfaced for review. A confidence score accompanies each enriched value.
Export Enriched Database
Download your enriched database with all original and new columns, push updates to your CRM, or stream enriched records to your data warehouse via webhook. Schedule recurring enrichment runs to keep the database current.
