Guidewire Software, Inc., commonly Guidewire, is an American software company based in San Mateo, California. It offers an industry platform for property and casualty (P&C) insurance carriers in the U.S. and worldwide.[1]

The company has been cited as being among the 50 most desirable mid-size Bay Area companies (101 to 500 employees) to work for 2010-2012,[2] and was in the "Top 50 Large Companies" in Glassdoor's Best Places To Work for both 2015 and 2016.[3]


The company was established in 2001 and founded by: Ken Branson, James Kwak, John Raguin, and Marcus Ryu from Ariba (and McKinsey, where James and Marcus had met); and John Seybold and Mark Shaw from Kana Software. In September 2011, Guidewire filed with the SEC to raise up to $100 million in an initial public offering (IPO) and first publicly traded on the NYSE in January 2012.[4] Guidewire was later cited as being one of the top IPOs of 2012,[5] even #1.[6]

In 2011, Guidewire settled a patent related lawsuit with Accenture regarding their claims management software.[7]

In 2013, Guidewire acquired Millbrook, Inc., a business intelligence company.[8] In 2016, Guidewire acquired ISCS (cloud computing),[9] FirstBest (underwriting)[10] and EagleEye Analytics.[11] In 2017, Guidewire acquired Cyence, a cyber insurance company.[12]

On August 5, 2019, Guidewire appointed Mike Rosenbaum as CEO.[13][14]


Guidewire is a recurring revenue software company as it sells term licenses. The company also sells its software as a service on a subscription revenue basis. Its three main software products are ClaimCenter, PolicyCenter, and BillingCenter, each servicing a major component of a P&C insurance carrier.[1] There are a number of add-on modules, as well as an increasing number of value-added online services provided via Guidewire Analytics and Guidewire Marketplace. Guidewire develops the Gosu programming language, released as open source in 2010.
