Guidewire to Buy hyperexponential for Up to $2.1 Billion, Expanding Underwriting Software
Oct. 29, 2026 • Article • Companies & Deals
Guidewire Software has agreed to acquire hyperexponential for $1.7 billion in cash, with up to $400 million more payable if specified post-closing recurring revenue targets are met. The agreement was announced on October 27, 2026. Subject to customary regulatory and antitrust conditions, the transaction is expected to close in the second quarter of Guidewire’s fiscal 2027.
The deal would bring hyperexponential’s pricing and underwriting software, including hx Renew and its hyperoperator agentic workbench, into Guidewire’s business. The platform supports decisions across more than $75 billion in annual commercial property and casualty gross written premium. At Guidewire’s Investor Day, CFO Jeff Cooper projected the acquisition would add at least 650 basis points to fiscal 2027 annual recurring revenue growth inorganically, followed by at least 150 basis points of organic ARR expansion annually from fiscal 2028. Guidewire plans to update its fiscal 2027 guidance in December 2026.
Guidewire Software has agreed to acquire hyperexponential in a transaction worth up to $2.1 billion, bringing pricing and underwriting tools for commercial property and casualty insurance into its software business. The agreement, announced on October 27, 2026, combines a $1.7 billion cash purchase price with up to $400 million tied to post-closing recurring revenue targets. It also extends an existing commercial partnership between the companies.
The acquisition would give Guidewire ownership of hx Renew and hyperoperator, an agentic workbench designed to help insurers move from incoming submissions toward pricing decisions. Whether those tools deliver the expected financial benefits remains to be seen: the transaction has not closed, and part of the consideration depends on future revenue performance.
Purchase price, financing and closing
The $1.7 billion base price is subject to customary adjustments. The additional consideration is contingent on hyperexponential meeting specified recurring revenue targets after closing, making $2.1 billion the maximum stated consideration rather than the upfront payment.
Guidewire has secured a binding debt commitment from Bank of America, N.A. and Citibank, N.A. for a $1.0 billion senior secured term loan A facility. The loan matures on December 2, 2029. Guidewire intends to fund the upfront cash price with that borrowing and existing cash on hand; the $1.0 billion debt commitment is part of the funding for the $1.7 billion base price, not an addition to it. The acquisition has no financing contingencies.
Guidewire expects to close the transaction in the second quarter of its fiscal 2027, the period ending January 31, 2027, subject to customary regulatory and antitrust closing conditions. Centerview Partners is Guidewire’s exclusive financial advisor, and Latham & Watkins is its legal counsel. J.P. Morgan advises hyperexponential, with Wilson Sonsini Goodrich & Rosati serving as its legal counsel.
What hyperexponential adds to underwriting
Founded in 2017 by former actuaries and software engineers Amrit Santhirasenan and Michael Johnson, hyperexponential develops software for commercial property and casualty pricing and underwriting. Its platform, centered on hx Renew and hyperoperator, supports decisions across more than $75 billion in annual commercial property and casualty gross written premium. That figure describes the premium associated with decisions the platform supports; it is not hyperexponential’s revenue or the value of the acquisition.
Hyperexponential launched hyperoperator in July 2026 as an agentic AI solution designed to automate underwriting workflows from submission intake to decision-ready pricing. In this setting, “agentic” describes software intended to carry out steps in a workflow, rather than merely provide information for a user to review. The supplied information describes the product’s intended role but does not establish how much of an insurer’s underwriting process it can complete without human involvement.
The companies were already integrated as commercial partners through Guidewire’s PartnerConnect Technology Alliance program before the acquisition agreement. Guidewire had also embedded its ProNavigator AI assistant into its InsuranceSuite and InsuranceNow core applications in April 2026. Those existing connections provide context for the purchase, though they do not by themselves demonstrate that the acquired tools will produce the projected revenue gains.
Revenue outlook and next steps
At Guidewire’s Investor Day on October 28, 2026, CFO Jeff Cooper said the acquisition was projected to add at least 650 basis points to fiscal 2027 annual recurring revenue, or ARR, growth inorganically. That measure reflects the expected contribution from buying the business. He also projected at least 150 basis points of organic ARR expansion annually beginning in fiscal 2028. One hundred basis points equal one percentage point.
The distinction between the two projections matters. The first concerns an expected acquisition-related boost to reported ARR growth in fiscal 2027; the later projection concerns growth after the acquired business is part of Guidewire. Both are forecasts, not results. Guidewire said it will formally update its second-quarter and full-year fiscal 2027 guidance on its scheduled quarterly earnings call in December 2026.
There was also a pre-existing leadership connection between the companies. Marcus Ryu, Guidewire’s co-founder and former chief executive, remains on Guidewire’s board and joined hyperexponential’s board as an independent director in January 2024, when Battery Ventures led a $73 million Series B funding round. The transaction now puts that established relationship, the companies’ product integration and Guidewire’s ARR projections under greater scrutiny as the closing process proceeds.

Whop announced a $200 million Series D on October 21, 2026, valuing the digital commerce platform at $5.1 billion. Sequoia Capital led the round, with Shopify Ventures participating. The valuation is about 3.2 times the $1.6 billion figure set during Tether’s strategic funding round in February 2026. Former Sequoia leader Doug Leone joined Whop’s board following the announcement. Whop said its annualized run-rate revenue exceeded $400 million as of September 2026, compared with $60 million at the beginning of 2025. It reported roughly 25,000 active business operators and an average blended transaction fee of approximately 6%. The company plans to expand its international team and establish regional offices in Europe and Colombia. It also reported more than 350,000 daily API calls across over 14,700 monthly active users of its newly launched Whop CLI and Model Context Protocol connectors, pointing to growing use of its developer tools.
London Stock Exchange Group has agreed to acquire credit intelligence provider Octus for $3.535 billion in cash. LSEG plans to fund the purchase entirely with external debt and expects the transaction to close in the first half of 2027, subject to customary regulatory approvals. Octus will join LSEG’s Data & Analytics division, with founder and CEO Kent Collier continuing to lead the business. The acquisition would add Octus’s private covenant and distressed credit data to LSEG’s debt-market offerings. LSEG plans to connect that information with products including Workspace, LPC and Yield Book, alongside Tradeweb. Octus is projected to generate more than $300 million in 2026 revenue at an adjusted EBITDA margin of approximately 40%. LSEG expects the deal to be neutral to adjusted earnings per share in its first full year after closing and accretive thereafter. It forecasts leverage reaching the upper end of its target range by the end of 2027.
CRB Group, the parent of Cross River Bank, agreed on October 20, 2026, to acquire Accrue, a fintech focused on merchant-branded digital wallets and customer loyalty. Accrue founder and CEO Michael Hershfield and his team are expected to join Cross River to lead its embedded wallet and loyalty offerings when the deal closes. Financial terms and a completion date have not been disclosed, and the transaction remains subject to customary closing conditions. The companies already had a banking relationship: Cross River held deposited funds and issued Visa debit cards for Accrue programs. The acquisition would bring Accrue’s wallet capabilities into that existing arrangement. Closed-loop wallets can keep payments and refunds within a merchant’s branded balance, offering an alternative to routing every transaction through card networks. The deal also illustrates why embedded finance providers are looking beyond payment-processing margins toward wallet software and stored-value services, though the companies have not disclosed the acquisition’s expected financial impact.
Hyperlayer has raised £19.5 million in a Series A2 round led by existing investor Flintlock Capital, valuing the company at £195 million post-money. Mouro Capital and Susquehanna Private Equity Investments also participated. The funding brings Hyperlayer’s capital raised over the trailing 12 months to approximately £50 million, following a £30 million financing in late 2025. The company develops Layer Core, a programmable overlay designed to let banks manage product logic, pricing and automated compliance above their existing core systems, which continue to record ledger transactions. Hyperlayer says it has secured deployment mandates with unnamed Tier 1 banks in Europe and North America. The round supports an international rollout following its US market launch in September 2026. Alongside the financing, Hyperlayer named Ben Helps chief operating officer and Louise Chan chief commercial officer. Flintlock Capital co-founder and general partner Joe Shamess joined its board.
Payward, the parent of crypto exchange Kraken, has signed a definitive agreement to acquire Saldo Finance Oy, the Finnish holding company of Lithuania-licensed Saldo Bank UAB. Announced on October 14, 2026, the transaction is expected to close in 2027, subject to customary approvals from the European Central Bank and the Bank of Lithuania. The purchase price was not disclosed. The deal would give Payward an EU-licensed bank alongside its existing European electronic money institution license. That license permits fund holding and payment processing but not lending or paying yield on customer deposits. Once the acquisition closes, Payward plans to use the banking license to offer interest-bearing euro deposits, consumer credit and direct SEPA clearing without intermediary banks. Saldo Bank already provides deposits, lending and banking-as-a-service infrastructure. Payward also plans to extend Saldo’s consumer credit card offering from Finland to Sweden in 2027.
