Attio Becomes the Default CRM for AI-Native Companies: $141M Raised, $52M Series B from GV, 5,000 Customers, 4x ARR Growth

SaaStr·medium signal

Attio has captured the AI-native startup market with customers including Lovable, Modal, and Replicate — mostly migrating from HubSpot. The company raised a $52M Series B led by Google Ventures, bringing total funding to $141M, and is on track to 4x ARR. Its differentiator is AI built natively into the data model: AI Attributes auto-fill custom fields using web research agents, call intelligence auto-populates CRM fields from transcripts, and agent workflows are included in paid plans rather than priced as separate credits. Setup takes weeks instead of quarters.
