Customer SupportRevenueHybridFullTime
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? Read more about us below.
At hyperexponential, 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Until now, insurance has been making billion-dollar decisions using outdated tools.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.
Our Customer Success team partners with hyperexponential’s largest and most complex customers to drive measurable value and long-term adoption of the hx platform. We build deep, strategic relationships with enterprise insurers, align on business outcomes, and ensure customers actively leverage core product capabilities to achieve those outcomes.
We work cross-functionally with Sales, Product and Delivery to create seamless experiences from onboarding through expansion. The team values proactive ownership, clear communication, and rigorous follow-through, empowering every member to shape customer success and influence our product roadmap.
As we scale, you’ll join a high-performing group that thrives on curiosity, collaboration, and impact. Your work will directly strengthen customer outcomes, account health, and hx’s market reputation.

You struggle to adapt to change or ambiguity, or find it difficult to collaborate across diverse teams.
You’re not energised by a culture that values ownership, feedback, and continuous learning.
If reading our Culture Document leaves you feeling neutral rather than energised, hx may not be the place where you’ll do your best work. We’re building something that asks for commitment and conviction, and we want you to feel excited by the opportunity to grow with us.
At hx, we’re committed to salary transparency. You’ll always have clarity on pay early in the process - our Talent Partner will share details with you during initial conversations - and we’re working towards publishing salary information for all roles globally.
Because we’re building at the intersection of technology/SaaS and insurance, our roles don’t always map neatly onto traditional benchmarks. Our approach is to design compensation that’s competitive in the market, fair across teams, and aligned with the impact our people make.
