Guidewire, whose software runs the policy and claims systems of many property and casualty insurers, agreed on Tuesday to buy Hyperexponential for $1.7 billion in cash, plus up to $400 million more if revenue targets are hit.

The London company, backed by Andreessen Horowitz and Battery Ventures with nearly $90 million raised, sells pricing and underwriting software used by nearly 600 insurers in 40 countries, and now calls itself an agentic underwriting company. Closing is expected next year.

The buyer is the insurance industry's system of record. Putting agents that price risk inside it sends them to every insurer on Guidewire without a separate sale.
