Senior Customer Success Manager

Senior Customer Success Manager

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. 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 at a $1.2 billion valuation.

We're hiring a Senior Customer Success Manager to own complex customer relationships across provider groups, MSOs, and health systems where our platform helps support meaningful patient populations. You'll partner with executive and operating leaders, manage accounts from launch through renewal and expansion, and serve as a trusted voice for your customers inside Assort.

This is a unique opportunity to help define what customer success looks like at a leading AI company, at a pivotal moment for our team.

What You'll Do

• Own complex accounts through the entire customer journey — serve as the primary relationship holder for provider groups, MSOs, and health systems, managing both executive relationships and operational details from launch through renewal and expansion.

• Be a strategic advisor on agentic AI — partner with C-suite and operating leaders to transform how patients experience care, expanding their vision of what's possible with AI and delivering measurable outcomes.

• Diagnose and solve with data — proactively identify, surface, and address risks and opportunities, and translate insights into recommendations that drive ROI, unlock productivity, and improve AI agent performance.

• Be the voice of the customer — develop deep fluency in Assort's product and partner closely with Sales, Implementation, Product, and Engineering to ensure our enterprise customers' needs shape what we build, sell, and deliver.

• Build scalable systems — own design and implementation of playbooks, processes, and tools that let us deliver consistent, world-class support as we rapidly grow.

• Travel to client sites (up to 25%)

• Top-tier project management abilities — you can manage multiple customer accounts, urgent priorities, and strategic initiatives, effectively and with composure.

• Exceptional communication skills & executive presence — you communicate with clarity, concision, and empathy, quickly earning the trust of executives.

• Strong analytical and problem-solving skills; comfortable using data to drive decisions.

• Builder's mindset — you've owned the creation of new systems, processes, or customer programs from scratch.

• Thrive in fast-moving, ambiguous environments, bring structure to chaos, and are willing to wear many hats as we set ourselves up for scale.

• Interest in or experience driving adoption of AI-native platforms in complex organizations.

• Experience working for early-stage startups or high-growth SaaS companies.
