Senior Customer Success Manager

Building Healthcare That Remembers Every time you call a doctor's office, the system forgets you the moment you hang up. You wait on hold, explain everything from scratch, get bounced between lines, and hope someone follows up. Everyone has felt this. No one should have to. At Assort Health, we're building one continuous conversation for every patient. An AI agent that knows who you are, remembers how you like to be reached, and carries that context from your first symptom to your full recovery. What began as the first voice AI agent to schedule a specialty appointment has become the largest proprietary specialty dataset in healthcare: 190 million patient interactions, 62,000 care protocols, 1.6 million decision pathways. We went from 15 people in 2025 and will cross 250 by the end of 2026. Revenue is up 20x in 15 months and we've raised $222 million, including a recent $120 million Series C https://www.assorthealth.com/blog/assort-health-raises-120-million-series-c-to-scale-largest-deployment-of-ai-agents-for-the-patient-journey at a $1.2 billion valuation. We've also been named to the Forbes Cloud 100 and the 2026 Enterprise Tech 30 as the only healthcare AI company on the list! Healthcare spends $1.1 trillion a year on administration instead of care.
