Neurology doesn’t run on hospital schedules. It runs on seconds. During a stroke, 1.9 million neurons die every minute, and most systems still waste those minutes in call center limbo. Sevaro Health was built to kill that lag, and today it’s putting muscle behind the mission with a $39 million oversubscribed Series B.
Founded in 2019 by Dr. Rajiv Narula, Sevaro Health didn’t come out of a boardroom brainstorm. It came from burnout, inefficiency, and the refusal to accept “business as usual” when lives were on the line. Dr. Rajiv Narula walked away from a neurointerventional radiology fellowship, went three years without a paycheck, and instead built Synapse AI, a platform that connects emergency teams to neurologists in under 45 seconds. Not “on hold.” Not “when the transfer clears.” Forty-five seconds, period.
The new round, co-led by Valtruis, the healthcare investment platform from Welsh, Carson, Anderson & Stowe, and Intermountain Ventures, the innovation fund of Intermountain Health, pushes Sevaro’s disclosed total to roughly $85 million. Returning investors APA and Catalyst backed the round as well, recognizing that Sevaro isn’t just selling software, it’s selling time. And time is the most valuable drug in neurology.
The data speaks louder than pitch decks. Hospitals using Sevaro slash door-to-needle times by up to 55 percent. One dropped from 67 minutes to 34. tPA utilization averages 21 percent, transfers out drop by up to 90 percent, and one system saved over $4 million in its first year. Another pulled in more than $500,000 in reimbursements in just three months by keeping patients in-house. Average time to reach a neurologist? Twenty-five seconds. Those aren’t metrics; they’re lifelines.
Series B capital is fuel for expansion. Sevaro is scaling its hybrid workforce model to ease physician shortages, deepening hospital integrations, and building out Virtual Institutes of Neuroscience Excellence. The company is also pushing beyond neurology into hospitalist medicine, cardiology, infectious disease, behavioral health, surgery, neurosurgery, and neurointerventional radiology. When you’ve proven that seconds can be saved, the obvious move is to apply that standard everywhere.
Behind the platform is a leadership bench with range. Alongside Dr. Rajiv Narula are Jason Bond, CFO and SVP of Strategy, with finance chops from CityMD, Mount Sinai, and Yale New Haven Health. On the clinical side, Dr. Sam Saha drives regional medical leadership, while Dr. Rami-James Assadi directs stroke programs with precision honed at Washington University. The roster reflects a culture where technology, medicine, and execution aren’t separate, they’re fused.
Valtruis, Intermountain Ventures, APA, and Catalyst didn’t just invest in another telehealth company. They invested in a system that treats time as medicine and refuses to waste it. Sevaro Health isn’t just scaling a business, it’s forcing hospitals to redefine what fast really means.
