Customer Success Manager

Hi, I’m James, Head of Customer Success at hx. I’m also an Arsenal season ticket holder and owner of Daisy, our team mascot and an official member of the CS team. Her responsibilities mainly include boosting morale, appearing on calls and avoiding anything that looks like account admin. Customer Success at hx is about much more than account management. We work with some of the world’s largest insurers to make sure hx is driving real outcomes across pricing, underwriting and portfolio strategy. Our Global Customer Success team is currently eight people, and we’re looking for someone to join us as we continue to grow. You’ll work closely with some of our largest and most complex customers, building trusted relationships with senior stakeholders, driving adoption, managing renewals and turning customer insight into better product, delivery and commercial decisions. It’s a great opportunity for someone who enjoys complex enterprise relationships, wants real ownership and is excited to help shape how Customer Success continues to scale at hx. Sounds interesting?

About Halcyon Labs (hx) At Halcyon Labs, we’re building the AI-powered platform that enables the world’s most critical decisions in a $7 trillion industry - which risks to take, and how to price them. These are the decisions that shape real-world outcomes: whether rockets successfully launch into space, autonomous vehicles make it to market, or communities recover after major storms. Until now, insurance has been making billion-dollar decisions using outdated tools. We’re changing that. Our platform brings together data, AI, and human expertise to give insurers the fastest path from submission to decision - helping them move faster, act smarter, and take on more risk with confidence. Backed by a16z, Highland Europe, and Battery Ventures, we’re scaling globally - already trusted by nearly 50 of the world’s largest insurers, with zero churn and billions in premiums flowing through hx. What began as a single product in one market has rapidly evolved into a multi-product, multi-territory platform powering every stage of pricing and underwriting. AI is at the core of what we do - from building the world’s first domain-specific AI peer programmer for insurance (think GitHub Copilot with a PhD in actuarial science) to shaping agentic workflows that reinvent how this industry operates. What makes hx different is the people who build it. Here, impact isn’t tied to title or tenure; it’s defined by the challenges you take on and the discipline you bring. Surrounded by peers who stretch you, you’ll do the best, hardest work of your life in a company engineered to endure. If that sounds like you, join us in building what comes next.
