Who is Attio best for?
A good fit if you
- GTM engineers who want to design their own objects and attributes, for example a custom Signals or Partners object fed from Clay.
- Small teams that want a usable free CRM: up to 3 seats, 3 objects and 50,000 records at no cost.
- Clay-heavy stacks, since Clay's native Attio integration can import, create, update and upsert records and list entries.
Look elsewhere if you
- Teams that want CRM, marketing automation, landing pages and a help desk from one vendor; Attio focuses on the CRM and relationship data.
- Larger teams on a tight budget who need more than 10 seats, since seat counts above 10 start at the Pro plan (£59 per user a month billed annually).
- Buyers who need a published SOC 2 report: Attio's Trust Center lists ISO 27001:2022, GDPR and CCPA, not SOC 2.
Does Attio integrate with Clay and your CRM?
- Clay
- Native Clay integration. Attio is in Clay's integrations directory (included in Clay's Growth plan and above). Clay can import records from any Attio object or list (up to 50,000 records), look up records (free, up to 10 matches), and create, update or upsert records and list entries for 1 Clay credit per run. Connecting requires an Attio workspace admin to authorise via OAuth. (source)
- Integrations
- Native apps for Gmail, Outlook, Slack, Zapier, Segment and Mailchimp, a Clay app built by Clay, a Make-maintained Attio app on Make, and a REST API. n8n has no built-in Attio node, so n8n users connect through its HTTP Request node. (source)
- GDPR
- Attio's Data Processing Addendum (last updated September 2026) forms part of its Customer Agreement and covers the GDPR and UK GDPR, using the EU Standard Contractual Clauses with the UK Addendum for transfers. The platform is hosted on Google Cloud Platform, with backups in a different geographic region; the DPA does not name specific regions. Attio's Trust Center lists ISO 27001:2022, GDPR and CCPA, and publishes its sub-processor list. (source)
