About Attio
The CRM built around your data model, not the vendor's.
Attio is a London-based CRM founded by Nicolas Sharp and Alexander Christie, publicly launched in 2023 and backed by a 2025 Series B led by GV that brought total funding above $100 million. The product targets SaaS scale-ups that outgrow HubSpot's fixed schema and refuse to take on Salesforce's admin weight. Customers on its own site include Modal, Flatfile, Replicate, Snackpass, Bravado and Union Square Ventures.
Attio's data model is the reason most teams pick it. People, Companies, Deals and Workspaces are standard, but every object has first-class custom attributes and custom objects land next to them with the same API treatment. Lists group records for a playbook rather than duplicating the record. AI features sit on top of that schema: enrichment, research agents and field-filling agents read and write the same objects your team edits by hand.
The point of pulling Attio into a warehouse is that the flexibility that makes it attractive also makes it easy to lose the thread. A custom attribute invented by one rep for one deal shows up on twelve thousand records six months later, and commission runs, churn models and board reporting each interpret it differently. In a warehouse, Attio's objects sit next to the Stripe subscription, the Gong call and the Intercom conversation, and the weekly revenue review runs on the joined picture instead of the CRM snapshot.
