Our take
hyperexponential was created to provide modelling software to help people and businesses build, deploy and manage analytical models that work with small, sparse and fragmented datasets. Its goal is to make teams more agile, collaborate more deeply, and work more productively.
hyperexponential's pricing and data-driven decision-making software is built for the speciality and commercial insurance markets. The product has broad applications, but the company's initial focus is on speciality insurance, a sector the founders know well, having worked there for more than a decade.
The company's making a name for itself too, working with some of Europe's biggest insurers to transform how pricing decisions are made. And its newest launch, hx AI, blends powerful AI with its core platform to help insurers build smarter models, faster. It's a strong signal that hyperexponential is not just growing, but ready to lead the way.
