Guidewire Software has staked its claim on providing software to the insurance industry. The company's InsuranceSuite offers applications to the property and casualty insurance industry for underwriting, policy administration (PolicyCenter), claims management (ClaimsCenter), and billing (BillingCenter). Its software is intended to replace paper-based processes and legacy systems built around outdated programming languages. Guidewire counts about 100 customers in a dozen countries, including Amica, Nationwide, and Zurich Financial Services. Outside the US, it has offices in Europe, Asia, Australia, and Canada. Guidewire filed a $100 million initial public offering in September 2011.
