ABOUT AURELIAN Aurelian builds AI tools that help 911 centers handle more with less, so telecommunicators can stay focused on what matters most and communities get the response they need. AVA is a conversational AI agent that answers non-emergency calls; the agent routes, triages, and resolves the calls without any human intervention. By handling administrative calls like noise complaints, lost dogs, and parking inquiries, AVA eliminates hold times and lets call-takers focus their energy on actual emergencies. CORA supports call-takers on the calls that matter most. CORA is an on-screen assistant that delivers real-time SOP checklists, smart reminders, and contextual guidance as an emergency call unfolds, so dispatchers stay calm, consistent, and confident when every second counts. When AVA detects an emergency mid-call, it transfers the caller to a telecommunicator and passes along the caller details, location, incident type, and key statements directly into CORA. The call-taker never starts from scratch. The problem we're solving is serious. The average emergency communications center is 30% understaffed nationwide. Staffing shortages drive burnout and attrition, which makes the shortage worse. Meanwhile, 60-80% of the calls coming in aren't even emergencies at all. Aurelian addresses both sides of that equation: AVA reduces unnecessary call volume, and CORA makes every emergency call more manageable for the people handling it. Aurelian is live in centers across the country, answering thousands of non-emergency calls every day, and is backed by New Enterprise Associates and Y Combinator. Aurelian is growing rapidly; we are hiring people who want to help scale this work and make a real difference in public safety infrastructure for communities across the country.
