Attio is a modern, object-based CRM that lets fast-moving go-to-market teams model their entire workflow using custom objects, relationships, and attributes, with a Lists-based interface adaptable beyond sales to customer success, partnerships, and fundraising. Its AI-native approach automatically enriches contact records, handles data cleanup, and syncs email and calendar data to build relationship timelines, while real-time collaboration features make it feel more like Notion than Salesforce. The platform includes a modern API, Call Intelligence, sophisticated reporting, and a generous free tier for up to 3 users, though it requires more upfront configuration than out-of-the-box CRMs.
