Best for: Startups and modern GTM teams who want a CRM their automations can drive.

The CRM built like a data platform. API-first, fast, and friendly to agents.
Attio ships a first-party hosted MCP server at mcp.attio.com (OAuth, official) plus a public REST API over every record and attribute, so Claude and other agents can read and write the pipeline directly.
The verdict: The best CRM foundation if your stack is heading toward agents and automation.
What's good
- Genuinely API-first: every object and attribute is reachable programmatically
- Fast, flexible data model that maps to how you actually sell
- Clean enough that reps will use it without a fight
What's not
- Younger ecosystem than Salesforce or HubSpot, fewer turnkey integrations
- Reporting is improving but not yet enterprise-grade
