Guidewire Software
Guidewire Software is an American technology company that provides an industry platform for property and casualty (P&C) insurance carriers worldwide.[^c1] Headquartered in San Mateo, California, the company serves insurers that collectively represent approximately 25% of the global direct written premium in the P&C insurance market.[^c2] Founded in 2001, Guidewire has grown from a startup focused on replacing legacy mainframe systems to the dominant vendor in the P&C core systems market, with approximately 22% market share in that segment.[^c4]
The company's core InsuranceSuite comprises three products—ClaimCenter, PolicyCenter, and BillingCenter—each managing a major component of an insurer's operations. These are supplemented by InsuranceNow for regional and mid-market insurers, the Guidewire Data Platform for analytics, and the Guidewire Marketplace for third-party integrations. Guidewire's mission is to power insurance agility through a trusted, scalable platform.[^c3] Over 570 insurers in 42 countries run on Guidewire software.
Since 2020, Guidewire has been transitioning its customer base from on-premises deployments to Guidewire Cloud, a purpose-built SaaS platform hosted on Amazon Web Services. By late 2024, 51% of customers had selected the cloud platform,[^c5] and annual recurring revenue had reached $864 million, with targets of $1 billion in fiscal year 2025 and $1.5 billion by fiscal year 2028.[^c6] The company has been recognized on Glassdoor's Best Places to Work lists and its annual Connections conference drew more than 3,200 attendees from over 30 countries in 2024.[^c7]
