Guidewire buys Hyperexponential for $1.7B to put AI agents in underwriting

An insurance pricing team used to be the hardest part of a commercial policy to automate. Guidewire said on 27 October that it will buy Hyperexponential. The price is $1.7 billion in cash. Up to $400 million more will follow if revenue targets are met. The goal is to make underwriting teams work alongside AI agents.

Guidewire runs the policy, billing and claims systems used by property and casualty insurers. Hyperexponential, a London company founded in 2017, builds the pricing and risk-decision layer. That layer sits in front of a Guidewire system. The press release names Aviva, Allianz, Sompo, Beazley, Markel, HDI, Cincinnati Financial, Convex and Bowhead as customers. Guidewire says the platform now powers underwriting across more than $75 billion in annual commercial P&C premium.

What the deal pays for

Guidewire's statement calls the goal "agentic underwriting". AI agents assess risk, price policies and make decisions. Human underwriters and actuaries work alongside them. Hyperexponential's own site describes the jobs its software does. These are submission triage, risk assessment, renewals and portfolio monitoring.

The base price is $1.7 billion in cash. The $400 million in contingent payments is tied to recurring-revenue targets, Guidewire said. The deal is being funded with a $1 billion term loan plus existing cash. It is expected to close in the second quarter of Guidewire's fiscal year 2027.

What each company says

Guidewire CEO Mike Rosenbaum said in the release that insurance is a complex industry. The quality of risk decisions has a large impact on business outcomes. He said the two companies will "deliver industry-specific AI solutions that will transform commercial underwriting".

Hyperexponential CEO Amrit Santhirasenan is the company's co-founder. He said the company was built on one belief. Underwriting judgement is the highest-leverage work insurers do. The combined business will give insurers one view, he said. The view runs from submission to bind, and from the individual risk to the whole portfolio.

What TechCrunch adds

TechCrunch reports that Hyperexponential's platform is used by nearly 600 insurers across 40 countries. The company has raised close to $90 million from backers. Those backers include Andreessen Horowitz and Battery Ventures. TechCrunch values the full deal at around $2 billion once the earn-out is included. It is expected to close in 2027.

A big incumbent is paying $2 billion for an agentic layer. That is a signal about where enterprise AI money is going. The insurer stays the customer of record. The shape of the judgement it buys is now a vendor's. For a team selling software into regulated industries, that is the easier deal to close. Pick a specific job a human does today. Wrap it in evaluation and audit. Sell it to someone who already owns the system of record.
