Attio is a CRM platform designed for modern GTM organizations, built on a JavaScript/TypeScript/React frontend with Node.js and Go backends, deployed across GCP and AWS. The company is in active scaling mode — engineering-heavy hiring (32 roles), real-time infrastructure work, and architecture redesigns signal a shift from monolithic CRM toward an AI-native, multi-tenant platform capable of handling millions of users. Integration velocity (Zapier, Tray.io, n8n, Segment, Rudderstack, Stripe) and no-code extensibility are core to their product strategy.
