The Problem

Why Most Data Enrichment Tools Waste Your Budget

Single-provider tools find only part of your contacts. You end up juggling multiple subscriptions, paying for empty results, and still getting bad data.

Miss Rate40-60%

Typical single-provider coverage

Industry estimates put single-provider coverage of B2B contacts at roughly 40-60%. You pay full price for a tool that cannot find a large share of your leads.

Price Tag$$$

Complex pricing for workflow tools

Tools like Clay bill credits on top of a monthly plan and still require manual workflow building for every enrichment sequence. Costs are hard to predict.

Data Decay~30%

Annual data decay (industry estimate)

B2B contact data is commonly estimated to decay by around 30% per year. Job changes, company moves, email bounces — without regular enrichment, your database goes stale in months.

No ValidationFew

Quality checks in most tools

Many enrichment platforms write raw data into your CRM with little validation. Formatting errors, duplicates, and outdated records go straight into your pipeline.

The Bottom Line

You're paying premium prices for partial coverage — and still importing dirty data into your CRM.

Waterfall across providers and check every field before write. That's what enrichment should look like.

The Solution

Data Enrichment Software That Actually Delivers

ListPlus combines waterfall enrichment, AI-powered cleaning, and CRM sync in one platform. Import your contacts, enrich them, and sync clean data back when you're ready.

Import

CRM Integration — Import & Two-Way Sync

Pull contacts from HubSpot, Salesforce, Pipedrive, or CSV. Enriched data syncs back to your CRM when you run the sync — no manual exports or re-imports.

  • HubSpot, Salesforce, Pipedrive via Pipedream (OAuth, no API keys)
  • CSV, Excel, and Google Sheets import with auto-mapping
  • Two-way sync — write enriched data back with one action
  • Fill only empty cells — keep your existing values

  • REST API and MCP server per list, self-describing
  • Claude, ChatGPT, or custom agents can enrich and query
  • Permissions: hidden columns, write whitelist, fill-only-empty, rate limit
  • Dynamic sublists by criteria — select what is ready and send it on

Enrichment That Scales With Your Lists

Waterfall Enrichment

ListPlus picks the best provider for the input you have — LinkedIn URL, email, name + company, or domain. If the first provider misses, the next one takes over. You get more coverage at a predictable cost.

Sublists and Routing

Define criteria once. Dynamic sublists show which contacts meet them, and you send what is ready on to Lemlist, Instantly, Smartlead, a webhook, n8n, or your CRM.

AI Agent Access

Enrichment, checks, and updates are available via REST API and MCP. Let Claude, ChatGPT, or your own AI agents work on your lists within the permissions you set.

From $55/mo

Basic plan is free: import up to 25,000 records, edit 5,000, 25 credits. Pro at $55/mo (100,000 records, 250 credits, Google Sheets, Airtable, Lemlist). Premium at $149/mo (1,000,000 records, 1,000 credits) adds HubSpot, Salesforce, Pipedrive and Notion. The AI Agent API is included in every plan, even the free one. Credits never expire.

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 multiple data providers in a waterfall, running 100+ quality checks, and syncing clean data 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 best provider for that input type. If it misses, the next provider in the chain tries — FullEnrich (which itself waterfalls through 20+ sources), Prospeo, CompanyEnrich, Serper, and others. This gives you more coverage than any single provider.

Which data providers are included?

ListPlus integrates multiple B2B data providers: FullEnrich (a waterfall across 20+ sources), Prospeo for LinkedIn and person lookup, CompanyEnrich and CompaniesAPI for company data, MillionVerifier for email verification, Serper for Google-powered LinkedIn URL search, and Enrich.so and HarvestAPI for LinkedIn profile data. You access all of them through a single interface and one credit system — no separate subscriptions needed.

How much does data enrichment cost?

1 credit is $0.035 with Pro or Premium, $0.06 on Basic. A verified email via Prospeo costs 2 credits, via FullEnrich 4 credits; a person lookup by name and company 6 credits; company data by domain 0.25 credits; email verification 0.3 credits. E-mail and phone lookups are charged only when found. Every plan includes credits (Basic 25, Pro 250, Premium 1,000), and packs start at 150 credits for $6. Credits never expire.

Is ListPlus GDPR compliant?

ListPlus is EU-hosted (Frankfurt) on Vercel (SOC 2 Type 2). CRM credentials are held by Pipedream (SOC 2 Type 2) via OAuth and can be revoked in your CRM. Lists are stored encrypted and persist until you delete them; temporary lookup results expire. Your lists are never sent to an AI model as a whole — AI commands get your instruction and the column structure, AI checks get only the values they check. Enrichment providers receive the identifier being enriched (email, LinkedIn URL, domain). A DPA is available on request for every plan.

How is ListPlus different from Clay?

Clay is built around visual workflows that you assemble for every enrichment sequence. ListPlus starts at $55/mo with a free plan, connects to your CRM via OAuth, and runs waterfall enrichment from a natural-language command. Key differences: EU hosting (Clay is US-hosted), 100+ built-in quality checks, a full read+write API and MCP server for AI agents, and e-mail and phone lookups charged only when found.
