About Hyperexponential (hx)

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Until now, insurance has been making billion-dollar decisions using outdated tools.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.

About The Role

Many actuarial careers are defined by deep expertise within a single company or portfolio. At hx, you’ll take that expertise and broaden its impact - working across multiple insurers and seeing first-hand how the most sophisticated organisations are reshaping their pricing and underwriting.

As an Actuarial Account Manager, your role sits at the heart of hx’s Revenue organisation, where client success and commercial growth come together. This role puts actuarial credibility at the centre. You’ll be a trusted partner to Chief Actuaries, Pricing Directors, and underwriting leaders, guiding them as they embed hx Renew and our wider platform across their businesses.

What You'll Be Doing

• Take ownership of a group of clients: build clear plans for how you’ll support them, prioritise where you can create the most impact, and deliver against agreed growth and retention goals.
• Broaden platform use: help clients expand from initial use cases into additional lines of business or geographies, ensuring measurable improvements in speed, quality, or insight.
• Drive value-led growth: lead renewal and expansion discussions based on outcomes achieved (e.g. faster model build, richer portfolio insight), ensuring clients see clear return on their investment.
• Bridge actuarial needs into delivery: work closely with Customer Success, Engineering, and Product teams to translate actuarial requirements into platform improvements and smooth client delivery.
• Champion AI and portfolio intelligence: introduce clients to practical ways of applying AI in actuarial workflows and help them adopt portfolio-level insights to inform pricing and underwriting decisions.
• Represent hx with credibility: lead conversations with senior actuaries and executives, contribute to client forums and industry events, and bring external insight back into our roadmap.

What You'll Need To Have Done

• Qualified or nearly-qualified actuary with 5–7 years’ pricing experience (insurance, reinsurance, or consulting).
• Built trust with senior stakeholders (Chief Actuary, Pricing Director, CUO) and influenced decisions beyond the model - process, governance, and portfolio choices.
• Demonstrated commercial awareness (consulting engagements, value cases, or client-facing delivery) with clear examples of outcomes you helped drive.
• Worked hands-on with actuarial tools, statistical modelling and large datasets; comfortable discussing methods, assumptions, and limitations with rigour.
• Applied AI pragmatically (e.g. analysis, documentation, reporting, QA) and can explain where it helps, where it doesn’t, and how you validated outputs.
• Communicated complex ideas clearly to technical and non-technical audiences; reliable written artefacts and executive-level presentations.

You’re Unlikely To Thrive Here If

• You’re content with established actuarial processes and aren’t curious about how AI, automation, and portfolio intelligence could reshape the discipline.
• You’d rather focus narrowly on technical tasks than engage clients in shaping how pricing and underwriting decisions are made and improved.
• You need a highly structured environment with predefined playbooks, rather than the opportunity to help define new standards for…
