AI Stroke raises $4.6M seed for pre-CT stroke triage AI — faster detection before hospital arrival
Summary
Israeli startup AI Stroke raised $4.6M in a seed round for their AI-powered pre-CT stroke triage platform that predicts large vessel occlusion severity from paramedic-collected data before patients reach a CT scanner. By directing high-severity stroke patients to thrombectomy-capable centers faster, the system aims to significantly reduce time-to-treatment — the critical metric for stroke outcome. The seed round supports a clinical validation study across Israeli emergency medical services.
Why it matters
"Time is brain" in stroke — every minute of delay costs approximately 1.9 million neurons. A pre-CT AI triage system that correctly redirects patients to thrombectomy centers before imaging could save thousands of lives annually. Israeli EMS infrastructure provides an ideal validation environment with dense paramedic coverage and excellent hospital data linkage.
