The Problem

Why Most Data Enrichment Tools Waste Your Budget

Single-provider tools miss 40-60% of contacts. You end up juggling multiple subscriptions, paying for empty results, and still getting bad data.

40-60%
Miss rate with single providers

No single data enrichment provider covers more than 60% of B2B contacts. You're paying full price for a tool that can't find half your leads.

$446+
Per month for Clay-style tools

Tools like Clay charge $446/mo just for CRM integration and still require manual workflow building. Per-credit pricing makes costs unpredictable.

30%
Annual data decay rate

B2B contact data decays at 30% per year. Job changes, company moves, email bounces — without continuous enrichment, your database rots in months.

0
Quality checks in most tools

Most enrichment platforms dump raw data into your CRM with zero validation. Formatting errors, duplicates, and outdated records go straight into your pipeline.

FAQ

Frequently Asked Questions

What is a data enrichment tool?
A data enrichment tool takes your existing contact or company data and fills in missing information — emails, phone numbers, job titles, company details, LinkedIn URLs. ListPlus goes beyond basic enrichment by combining 15+ data providers in a waterfall, running 107+ AI quality checks, and syncing clean data directly to your CRM. It's a complete B2B data enrichment platform, not just a single-provider lookup.
How does waterfall enrichment work?
Waterfall enrichment cascades through multiple data providers in sequence. When you enrich a contact, ListPlus first tries the most accurate provider for that data type. If it misses, the next provider in the chain tries, and so on through 15+ sources including FullEnrich (which itself waterfalls through Apollo, Hunter, Lusha, Cognism, ContactOut, and more), Prospeo, CompanyEnrich, and Serper. This maximizes your coverage compared to 40-60% with a single provider.
Which data providers are included?
ListPlus integrates 15+ B2B data providers: FullEnrich (cascading through Apollo, Hunter, Lusha, Cognism, ContactOut, LeadMagic, and more), Prospeo for LinkedIn and person lookup, CompanyEnrich for company intelligence, Serper for Google-powered LinkedIn URL search, and Enrich.so for LinkedIn profile data. You access all providers through a single interface — no separate subscriptions needed.
How much does data enrichment cost?
Email enrichment starts at €0.02 per contact through the waterfall. Company data is €0.005 per lookup. Full person enrichment (email + phone + company data) costs €0.04-0.08 depending on the provider path. You only pay for successful enrichments — if no provider finds data, you pay nothing. Pro starts at €39/mo with all providers. Premium at €79/mo adds CRM sync and AI Agent API.
Is ListPlus GDPR compliant?
Yes. ListPlus is hosted on EU infrastructure (Frankfurt) via Vercel (SOC 2 Type 2, ISO 27001). CRM credentials are managed by Pipedream (SOC 2 Type 2). All data is processed within the EU. Contact data is stored in encrypted Redis with automatic TTL — data auto-deletes after processing. We never share your data with third parties, and you can request full data deletion at any time.
How is ListPlus different from Clay?
Clay charges $446+/mo for CRM integration and requires manual workflow building for every enrichment sequence. ListPlus starts at €39/mo, connects to your CRM in one click, and runs waterfall enrichment automatically. Key differences: EU data residency (Clay is US-only), 107+ built-in quality checks (Clay has none), AI agent API access via REST and MCP, and pay-only-for-results pricing instead of per-credit charges.
