ISG studies Guidewire services ecosystem

Information Services Group said on May 18 that it has launched a study of companies that help insurers adopt and optimize Guidewire’s core insurance platform, with findings due in October 2026. The Stamford, Connecticut-based advisory firm said the research will assess providers offering consulting, implementation, AI accelerators and cloud-based transformation services for property and casualty insurers. The study gives carriers a current map of the firms competing to run Guidewire programs at a time when many insurers are still moving core systems to the cloud. ISG said more than 40 providers are in scope. ### Which part of the Guidewire market is ISG actually studying? ISG said the report will cover end-to-end Guidewire services rather than Guidewire software itself. That means the focus is on firms hired to plan migrations, configure core systems, manage delivery, run post-go-live support and help insurers improve operations after implementation. Guidewire’s own partner materials describe a large consulting ecosystem built around business transformation, strategy, implementation, integration and change management. Guidewire says its PartnerConnect network includes more than 28,000 technology consultants, systems integrators and solution providers, with consulting partners grouped into Select, Advantage and Global tiers. ### Why are services firms getting this much attention now? ISG said the study is aimed at insurers adopting and optimizing Guidewire through cloud-based transformation programs. That framing matches ISG’s 2025 Guidewire services report, which said insurers were replacing legacy systems with modular core platforms and migrating from on-premises deployments to Guidewire Cloud. (finance.yahoo.com) ISG’s 2025 report said providers were helping insurers manage complex migrations as existing Guidewire users moved to cloud deployments and new customers adopted the platform. That earlier report gives context for the new study: insurers are not only buying software licenses, but also outside help to configure products, manage project risk and support operations after launch.

ISG said the 2026 Guidewire Services Ecosystem study will analyze provider capabilities, innovation and best practices using its Provider Lens methodology. A brochure for the 2026 study says the report is intended to give business and IT buyers transparency on provider strengths and weaknesses. (ir.isg-one.com) Guidewire’s own partner framework gives one clue to the competitive spread ISG is likely to examine. Guidewire says Global Premier partners have made substantial investments in Guidewire and have long implementation track records, while other tiers include firms with different scale, specialization and market reach. Guidewire said in April 2025 that consulting partners had earned more than 250 specializations and that more than 26,000 consultants worldwide were trained or experienced in Guidewire products.

Guidewire says its broader partner ecosystem includes consulting and technology partners, plus more than 200 products and services on its marketplace. That does not mean every partner is in ISG’s study, but it does show the size of the surrounding ecosystem from which insurers choose implementation and optimization support. ISG has run similar Guidewire ecosystem assessments before. (guidewire.com) In a 2024 announcement covering both Duck Creek and Guidewire, ISG said it had distributed surveys to more than 40 providers worldwide for platform-services research. The new Guidewire study again uses a field of more than 40 providers, according to the May 18 announcement. (guidewire.com) ### What happens next for insurers and providers? ISG said the next step is publication of the Guidewire Services Ecosystem report in October 2026. Guidewire, meanwhile, continues to expand and classify its consulting ecosystem through PartnerConnect tiers and specializations, giving insurers another reference point as they evaluate providers for implementation, managed services and optimization work.
