ListPlus

What is data enrichment?

Data enrichment fills missing fields in your contact or company records by combining multiple external sources. ListPlus waterfalls through 15+ providers per record — typically email, phone, job title, company details, LinkedIn URL — and runs AI quality checks before the clean data reaches your CRM.

How does waterfall enrichment work?

For every field you want filled, ListPlus tries the most accurate provider first. If it misses, the next provider in the chain is called, and so on through 15+ sources (FullEnrich, Prospeo, CompanyEnrich, Hunter, Serper, Enrich.so, plus 10+ more). A single provider covers 40-60% of B2B contacts. A waterfall covers 85%+.

Which CRMs does ListPlus support?

Native bidirectional sync with HubSpot, Salesforce, and Pipedrive. Google Sheets and Airtable are supported. Any other tool with a REST API or Zapier/Pipedream connection works via our AI Agent API. OAuth-based connection, no developer setup.

How accurate is the data?

ListPlus only returns verified results. Emails go through SMTP verification; phone numbers through country-level normalization; company data is cross-checked across providers. When coverage is weak, the result is null — you pay nothing. Typical combined accuracy is 92-95% for emails and 85-90% for direct phone numbers.

Is ListPlus GDPR compliant?

Yes. Infrastructure runs in Frankfurt (Germany) on AWS eu-central-1. Data is processed in the EU and auto-deleted after enrichment. We are data processor per GDPR Art. 28 with a standard DPA available. AI models receive sanitized commands — never full contact data.

What's the difference between ListPlus and Clay?

Clay is a visual workflow builder a human operates — useful if you have a RevOps engineer who loves building waterfall flows in a canvas. ListPlus is an API any AI agent can call autonomously — one URL, self-describing schema, plus a built-in UI. Clay is the interface. ListPlus is the infrastructure.

How does the AI Agent API work?

Every ListPlus workspace exposes a single REST endpoint. An AI (Claude, GPT, Cursor, any MCP client) reads the URL, understands the available actions and filter conditions, and can query contacts, enrich data, or sync results back — without writing integration code. The URL is the token. No SDK, no auth headers to manage.

How much does ListPlus cost?

Free plan includes 250 records and 25 credits with basic enrichment and AI commands. Pro is €39/month for 5,000 records, Google Sheets and Airtable sync, plus automated workflows. Premium is €79/month for 100,000 records, HubSpot and Salesforce sync, AI Agent API, and your own API keys (50-80% cheaper provider prices). No per-seat pricing.
