Clay enriches.
Klozeo retains.
Clay is an execution platform — brilliant for enriching 5,000 leads with waterfall lookups from 50+ sources. But it's expensive and unwieldy as a long-term data store. Every read costs credits. There's no native MCP. Schema is table-based.
- Clay enriches → Klozeo stores. Push enriched contacts via API, Klozeo deduplicates on arrival.
- Score once, query forever. Define your scoring rules in Klozeo — no credits consumed per read.
- AI agents query Klozeo via MCP natively. No bridges. No credit overhead.

Klozeo — same workflow
Close keeps you in the app.
Klozeo gets out of your way.
Close is an excellent CRM for sales teams. But if your workflow involves AI agents, custom automation, or programmatic data access — it works against you.
