Insurance software provider Guidewire signed a definitive agreement to acquire London-based Hyperexponential, an artificial intelligence company focused on underwriting and pricing for commercial insurers. The deal is valued at up to USD 2.1 billion.
Guidewire will pay USD 1.7 billion in cash at closing, subject to customary adjustments. It will also pay up to USD 400 million more if Hyperexponential meets specified recurring-revenue targets.
A Push into Agentic Underwriting
Hyperexponential builds AI-native software that helps insurers price complex commercial risks. Its platform supports underwriters and actuaries as they assess exposure, model outcomes and set premiums.
The transaction marks one of the larger recent bets on AI in commercial insurance. Guidewire wants to expand its capabilities beyond core policy administration and claims systems into intelligent underwriting and pricing tools.
Guidewire said the acquisition will accelerate its move towards agentic underwriting. In this model, AI agents work alongside underwriters to evaluate risks, recommend pricing and support faster decision-making.
The company positions the deal as a way to set a new standard for how insurers use AI in commercial lines. It expects the technology to help carriers respond more quickly to complex and specialized risks.
Strategic Fit for Guidewire
Guidewire provides software to more than 570 property and casualty insurers across 44 countries. That installed base gives Hyperexponential a wide route to market for its underwriting and pricing technology.
For Guidewire, the acquisition adds specialist capability in commercial and specialty insurance, where pricing decisions often depend on large volumes of data and expert judgment. The company believes AI can improve both the speed and quality of those decisions.
The deal also reflects growing competition among insurance technology providers to embed generative and agentic AI into core workflows. Insurers are seeking tools that reduce manual work while preserving human oversight in high-stakes underwriting decisions.
