Atrium is an AI-powered relationship manager for investors, founders and executives who manage large networks. It connects to email and other communication channels, enriches contacts automatically, prioritises the inbox by who matters, prepares briefings before meetings and drafts replies, introductions and follow-ups for the user to approve.
The company was founded by Kevin Lu, a former investor at Australian venture firm Airtree, with co-founders Daniel Lum and Gerry Lu. In December 2025 it announced a $1.3 million pre-seed round from Airtree and TEN13 alongside US and Australian angel investors.
As of 2026 Atrium is offering early access to its product.
