Atrium

Atrium is a sales-effectiveness and sales-performance business intelligence platform for revenue teams. It continuously monitors sales KPIs to surface anomalies in rep and team performance, detects which behaviors and activities are driving (or dragging) output, and delivers AI-powered coaching recommendations to managers and reps. The product connects directly to Salesforce, HubSpot, data warehouses, and communication tools rather than exposing a public developer API. Founded in San Francisco by Jason Heidema (CEO) and Peter Kazanjy and backed by Andreessen Horowitz (a16z), Bullpen Capital, and Electric Capital, Atrium was acquired by Fullcast in 2025 and is now offered as Fullcast Performance; atriumhq.com redirects to fullcast.com and only the customer application login at app.atriumhq.com remains on the Atrium domain.

Atrium is profiled on the APIs.io network. Tagged areas include Company, Sales, Analytics, Business Intelligence, and Sales Performance.
