Guidewire buys underwriting AI startup hyperexponential for up to $2.1B
October 27, 2026
Deal Value
$2.1B
The deal bets that AI agents can start pricing risk and making underwriting calls, not just assisting human underwriters.
- Guidewire signed a definitive agreement to acquire London-based hyperexponential for a $1.7 billion cash base price, plus up to $400 million more tied to recurring revenue targets.
- hyperexponential builds AI-native underwriting and pricing software for commercial P&C insurers, and its platform has already powered decisions across more than $75 billion in annual commercial premium.
- Guidewire will fund the deal with $1 billion in new term loans from Bank of America and Citibank alongside cash on hand; closing isn't conditioned on securing that financing.
- Guidewire expects the acquisition to add at least 650 basis points to fiscal 2027 ARR growth and at least 150 basis points to organic growth starting fiscal 2028.
- hyperexponential was already a Guidewire PartnerConnect Technology Alliance Partner, so the acquisition converts an existing integration partnership into full ownership.
- The purchase shows core insurance software vendors racing to own the AI layer that actually sets prices and risk decisions, not just the policy administration systems around it.
