Attio
Collaborative, extensible CRM for teams that want to build a custom CRM with AI and advanced APIs
Overview
Attio is a collaborative CRM built to be extended and customized by technical teams: define custom business objects (accounts, contacts, opportunities or proprietary structures), wire data from dozens of tools, and build complex no-code workflows. The free plan covers up to 3 seats with 50,000 records; the Plus plan (€31/seat/month annual, €39 monthly) scales to 10 seats and 250,000 records; the Pro plan (€74/seat/month annual, €93 monthly) offers unlimited seats and 1 million records, right-sized for a growing SME. A custom Enterprise plan adds advanced security controls.
Attio offers no French interface: the product stays English-only. The platform's strength is its open architecture: a documented public API available on all plans including free, SDKs and Model Context Protocol (MCP) support let developers build deep integrations or AI agents that read and modify CRM data. Monthly pricing with a 20% annual discount makes the tool accessible from the start, but its flexible data model demands a real learning curve compared to off-the-shelf CRMs, and AI usage credits are billed separately in tiers from 5,000 to 50,000 monthly.
Our verdict
Best for technical teams or SMEs with in-house developers wanting an ultra-flexible, API-extensible CRM that plugs into a complex ecosystem. Not for you if you want an out-of-the-box CRM without technical setup: Attio's power comes at the cost of initial complexity, and nothing is translated to French.
