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.

"We're delighted to welcome Amrit Santhirasenan and the team at hyperexponential to Guidewire. There isn't another company in the world whose passion for insurance, technical ambition, and vision for the potential of AI in insurance align so closely with our own," said Mike Rosenbaum, chief executive officer, Guidewire. "Insurance is a distinctly complex industry, where the quality of risk decisions has an immense impact on business outcomes. Guidewire and hyperexponential are uniquely positioned to deliver industry-specific AI solutions that will transform commercial underwriting. Together we will bring greater and more scalable intelligence to the insurance decisions that will help underwrite the risks of tomorrow."

"We founded hyperexponential on the conviction that underwriting judgment is the highest-leverage work insurers do," said Amrit Santhirasenan, CEO and co-founder, hyperexponential. "Guidewire is the most trusted name in P&C insurance technology, with deep expertise in managing and safeguarding the policy and risk information insurers rely on throughout the insurance lifecycle. Together, we'll bring insight from submission to bind and from the individual risk to the entire portfolio. With hx and Guidewire, insurers will be able to respond to submissions faster and, more importantly, improve loss ratios and allocate capital more effectively."

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.
