The partnership with Arthur Ventures, an early-growth firm managing approximately $2 billion, will fuel the expansion of E3’s product roadmap. Unlike traditional alert systems that merely signal a crisis, the E3 platform integrates live floor plans, location-aware alerts, and accountability tools to guide evacuations or lockdowns.

Recent additions to the service include Roll Call, which syncs with student information systems, and a reunification module designed to track student-parent handoffs. CEO Dalton Mickelsen and founder PK Keller emphasized that the company’s growth is driven by a focus on practical utility for educators and emergency personnel. With over 100,000 active users, the platform aims to further penetrate the K-12 and healthcare sectors by prioritizing actionable data for high-stakes environments.
