Insurance software company Guidewire has entered into a definitive agreement to purchase London-based insurtech hyperexponential for a base price of $1.7 billion in cash, the companies announced on October 27, 2026. The transaction also includes up to $400 million in contingent consideration tied to recurring revenue milestones, bringing the total potential valuation to $2.1 billion. By adding hyperexponential's machine learning tools to its core software suite, Guidewire acquires hyperexponential to push deeper into commercial lines property and casualty (P&C) underwriting.
Founded in 2017, hyperexponential—also known as hx—provides an AI-native underwriting and pricing platform used by insurers, reinsurers, and managing general agents. Hyperexponential had previously disclosed $91 million in venture funding according to Coverager. The company's platform currently supports underwriting decisions across more than $75 billion in annual commercial P&C premium. Existing clients include global carriers such as Aviva, Allianz, Sompo, Beazley, Markel, HDI, Cincinnati Financial, Convex, and Bowhead.
Advancing Agentic Underwriting Across Commercial Lines
The combined company plans to expand what it terms "agentic underwriting," a system where autonomous software agents collaborate directly with underwriters and actuaries to assess complex risk submissions. According to Guidewire CEO Mike Rosenbaum, insurance outcomes hinge on the quality of risk selection, and domain-tailored software can transform commercial line workflows.
Amrit Santhirasenan, CEO and co-founder of hyperexponential, emphasized that underwriting judgment remains the highest-leverage activity for carriers. By integrating hyperexponential's pricing workbench with Guidewire's core policy management software, the companies intend to streamline workflows from submission triage through policy binding. Hyperexponential has already developed an AI agent named hyperoperator, which can ingest commercial policy submissions, flag missing information, check risk appetite, price the underlying exposure, and generate quote proposals for underwriter review, as reported by Insurance Innovation Reporter.
The companies cited research from analyst firm Celent regarding time-to-quote improvements. Celent observed that machine learning enables commercial P&C insurers to analyze unstructured datasets—such as telematics, satellite imagery, and historical loss files—to improve operational efficiency and decrease loss ratios by percentage points.
Financial Terms and Guidance Projections
To finance the $1.7 billion base purchase price, Guidewire secured binding debt commitments for a $1.0 billion new term loan facility from Bank of America, N.A. and Citibank, N.A., covering the remaining cash balance from existing balance sheet reserves. Guidewire reported that the acquisition will not alter the financial guidance it previously issued for the first quarter of fiscal year 2027 on September 3, 2026, according to FinTech Global.
Guidewire expects the acquisition to close during the second quarter of its fiscal year 2027. The company plans to issue second-quarter guidance and update its full-year fiscal 2027 outlook during its quarterly earnings call in December 2026.
Guidewire projects that hyperexponential will contribute at least 650 basis points to its fiscal year 2027 annual recurring revenue (ARR) growth on an inorganic basis. Beginning in fiscal year 2028, Guidewire anticipates the acquisition will provide a durable organic ARR growth boost of at least 150 basis points, while remaining aligned with long-term operating margin targets.
Market Integration and Deal Advisors
Hyperexponential was already an established member of Guidewire's PartnerConnect Technology Alliance program. Its existing Guidewire Accelerator will remain functional, allowing risk ratings to flow into underwriting work environments while feeding policy records back into portfolio steering models. Until the acquisition officially closes, both companies will continue operating independent product roadmaps.

Hyperexponential was advised by J.P. Morgan as exclusive financial advisor and Wilson Sonsini Goodrich & Rosati (UK) LLP as legal counsel.
