hyperexponential is the agentic platform for commercial P&C insurance underwriting.

The acquisition strengthens Guidewire's leadership in P&C technology and sets up the company to define agentic underwriting, a new approach in which AI agents work alongside underwriters and actuaries to assess risk, price it, and make decisions, from the most complex specialty risks to high-volume commercial business. Insurers will be able to respond to more submissions, faster, with pricing and risk decisions that consistently reflect their best underwriting judgment. This will enable insurers to write more profitable business, grow into new lines with confidence, and free underwriting teams to focus on the risks where their expertise matters most.

Underwriting speed and accuracy remain vital to pricing risk appropriately and maintaining portfolio resilience as P&C insurers face changing environmental, market, and regulatory conditions. AI-driven reductions in time-to-quote, among other factors, are having a significant effect on P&C insurer revenue, according to the Celent report "AI Trends Across the Insurance Value Chain: P&C Edition - North America." Celent notes that "...one industry consulting firm working with US and UK commercial P&C insurers found AI can improve underwriting efficiency significantly in complex lines and reduce loss ratios by percentage points by making use of previously unstructured data like telematics, satellite imagery, and loss history."

hyperexponential has established a leading position in AI-native underwriting and pricing, with a particularly strong presence among commercial and specialty insurers in the United Kingdom. The transaction is expected to contribute at least 650 basis points to Guidewire's fiscal year 2027 ARR growth on an inorganic basis and then, starting in fiscal year 2028, at least 150 basis points to Guidewire's durable organic ARR growth, further strengthening the company's long-term growth profile.
