The insurance software maker plans to pay $1.7 billion in cash, with up to $400 million more tied to revenue targets, to expand its risk-assessment and pricing tools.

Insurance software maker Guidewire plans to buy London-based hyperexponential for $1.7 billion in cash, plus up to $400 million if revenue targets are met, the company said on 27 October in a report carried by CNA. Hyperexponential says nearly 600 insurers across 40 countries use its software.
Guidewire already supplies software to property and casualty insurers. The purchase would add hyperexponential’s underwriting and pricing software for commercial insurers, which cover businesses’ property and liability risks.
Hyperexponential’s adoption figures appeared in TechCrunch on 27 October. They are the company’s own account of usage, rather than an independently verified count, and concern a different customer base from Guidewire’s reported footprint.
| Company | Insurers using its software | Countries |
|---|---|---|
| hyperexponential | Nearly 600, the company says | 40 |
| Guidewire | More than 570 property and casualty insurers | 44 |
Guidewire said hyperexponential’s software uses superintelligence (SI) for underwriting—the process of assessing risks for insurance cover—and pricing. Guidewire intends the acquisition to let SI software agents work alongside underwriters to assess risk, price it and make decisions. Those capabilities are an intended outcome of the pending deal, not demonstrated benefits of the acquisition.
Guidewire plans to fund the purchase with $1 billion in new term loans from Bank of America and Citibank, alongside cash it already holds. The company said the deal would not affect its first-quarter forecast.
Guidewire expects the acquisition to close in the second quarter of its fiscal 2027.
