Apollo and ZoomInfo are established B2B data platforms with massive contact databases and sales engagement tools. Entity Enricher serves a fundamentally different purpose: schema-driven, multi-model enrichment for any entity type, with AI-powered fusion and conflict resolution. Here is how they compare.
Uses multiple LLMs to research and enrich entities in real-time. Draws from the full breadth of AI model training data.
Looks up entities in a proprietary database of 275M+ contacts. Data is only as current as the last database update.
Define a schema for any entity: pharmaceutical compounds, legal entities, real estate properties, research papers, or anything else.
Purpose-built for B2B companies and contacts. Provides firmographic data, technographic data, and buyer intent signals.
Run 2+ AI models simultaneously. Field-level conflict detection resolves disagreements with structured reasoning and confidence scores.
Single authoritative database. No cross-validation mechanism. Data accuracy depends on Apollo/ZoomInfo's update frequency.
Bring your own LLM API keys. Pay your provider directly per token. No monthly platform fee, no per-seat charges.
$49-249/month per seat with credit limits. Enterprise plans with custom pricing. Additional credits cost extra.

Entity Enricher and Apollo/ZoomInfo are not mutually exclusive. Many teams use Apollo for initial B2B prospecting and contact discovery, then feed those contacts into Entity Enricher with a custom schema to add domain-specific intelligence that Apollo does not provide -- competitive analysis, technology stack details, regulatory compliance status, or any other custom fields.
Entity Enricher's batch processing supports URL fetch with authentication, so you can pull entity lists directly from Apollo's API and enrich them with your custom schema in a single workflow.
