Senior Customer Success Manager

About this role

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, and no one should have to.

At Assort Health, we're building Healthcare That Remembers.

We are creating one continuous conversation for every patient, across every modality: call, text, and message. An AI agent that knows who you are, remembers how you like to be reached, notices when something in your care changes, and carries that context from your first symptom to your full recovery.

Assort is the fastest-growing AI agents company in healthcare. Our omnichannel agents handle calls, texts, and chats from end to end, integrating with EHR and PMS systems and the real-world preferences of every provider so patients reach the care they need without the wait.

What began as the first voice AI agent to schedule a specialty appointment has become a platform spanning scheduling, intake, referrals, document processing, medication refills, eligibility verification, lab requests, and payments. That expansion has been powered by more than 190 million patient interactions, 62,000 care protocols, and 1.6 million decision pathways, creating the largest proprietary specialty dataset in healthcare.

Since launching the first AI agent to answer a patient phone call in 2023, Assort has helped healthcare organizations dramatically reduce hold times, automate administrative work, and improve access to care for millions of patients.

We are growing fast. We went from 15 people in 2025 to 170 today and are doubling again this year. Revenue has grown 20x in the last 15 months.

Backed by Menlo Ventures, Lightspeed, First Round, and other leading investors, Assort has raised more than $222 million, including a recent $120 million Series C. We were named to the 2026 Enterprise Tech 30 as the only healthcare AI company on the list and to the Forbes Cloud 100 alongside OpenAI, Anthropic, Stripe, and Ramp.

Healthcare spends over $1.1 trillion every year on administrative work instead of patient care. We believe AI can change that. The problem is enormous, the timing is right, and we are building the team to solve it.

If you want to help build the system that hundreds of millions of people will rely on to access care, we'd love to meet you.
