In a healthcare world where billions bleed from cracks no one wants to plug, Arine is doing what most systems won’t, fixing the actual problem. Medication mismanagement is a $528 billion wound. Not theoretical, not forecasted, actual dollars flushed thanks to misprescribed, mismanaged, or misunderstood meds. Most startups would’ve built another app that sends push notifications to take your statins. Arine built a full-stack, AI-powered command center that can steer clinical interventions across 25 million lives like it’s air traffic control for the human body.
Founded in 2017, commercially live by 2019, Arine isn’t some overnight pitch deck playing house in healthcare. This team’s been grinding. Dr. Yoona Kim, co-founder and CEO, is a triple threat: Stanford-trained in biology, UCSF Pharm.D., and a Ph.D. in health economics. She’s navigated the trenches of Gilead, Novartis, and Proteus Digital Health. Beside her, Penjit “Boom” Moorhead, co-founder and CTO, brings the kind of systems physics background that doesn’t just build scalable infrastructure, it engineers it to think. Together, they didn’t just launch a company. They launched a movement inside the machine.
Arine’s platform is what happens when deep clinical expertise meets real-world AI. We’re talking thousands of algorithms cutting through noisy data to serve up targeted interventions that actually change outcomes. These aren’t dashboards for the sake of dashboards. This is medication intelligence with teeth, clinical, behavioral, and SDoH data all woven together to drive action, not analysis paralysis.
Since raising a $29M Series B in 2022 (confirmed, real, and clean), with support from 111° West Capital, MBX Capital, Katalyst Ventures, New Leaf Venture Partners, and SCAN Group, Arine has taken the quiet route to domination: 272 employees, 100% client retention, and more than 40 health plans onboard. They’re not just reducing hospitalizations by 40%, they’re reducing cost of care by over 10% for national health plans, PBMs, and Blues.
And just in case you thought this was hype: Inc. ranked them 236 on the 2024 Inc. 5000, and 5th fastest in the AI category. The co-founders just landed on the 2025 Inc. Female Founders 500 list. Real growth. Real recognition. No smoke.
While others try to scale “reminders” or chase another ML use case for insurance pre-auth, Arine is scaling outcomes in value-based care. At a time when healthcare screams for reform, they’re quietly engineering it, prescriber by prescriber, patient by patient, plan by plan. Clinical expertise and AI, finally on the same team.
And if you’re running a plan, a system, or even just doing the math, the message is clear: medication is where care begins and waste ends. Arine’s not here to play doctor. They’re here to give them the tools that actually work.
