What SilverStripe does
Founded in 2000 in Wellington, Aotearoa New Zealand, Silverstripe develops and maintains the open-source Silverstripe CMS, a PHP-based content management system built on the Symfony framework, while operating as a full-service digital agency. The company delivers strategy, design, development, QA testing, and managed services to New Zealand government agencies, large enterprises, and educational institutions, anchored by a portfolio of marquee engagements including Immigration New Zealand, the 2023 Stats NZ Census Internet Collection System (which captured 6.2 million forms), Tourism New Zealand's re-platforming of newzealand.com, Westpac New Zealand, and multiple universities. All three co-founders remain on the board, with approximately 65-70 employees across Wellington and Auckland offices.
The company's revenue model combines project-based professional services with three productized recurring offerings: Silverstripe Cloud (managed AWS hosting with ISO/IEC 27001 certification and a 99% uptime guarantee), Silverstripe Search (a managed Elasticsearch-powered search service with self-service curation capabilities and te reo Māori macron support), and DPI Connect (a digital public infrastructure platform providing pre-built connections for secure identity, digital credentials, forms, payments, and notifications). Distribution is primarily direct enterprise sales supplemented by the silverstripe.org self-serve open-source channel and a tier 1 supplier listing on the NZ Government Pae Hokohoko Marketplace.
The technology stack combines Silverstripe CMS as the core content layer with modular integration capabilities spanning Fluent (multilingual translation across 20+ markets), Elastic Enterprise Search, PeopleSoft, Google Maps API, Windcave payments, and User Defined Forms. The Silverstripe CMS codebase is open source with a global developer community contributing through add-ons and StripeCon events. Recent strategic activity centers on launching AI-assisted editorial tooling within CMS, scaling DPI Connect through an international proof of concept with the South African Presidency, and productizing managed search and cloud services into subscription revenue streams. The firm is privately held with no disclosed external institutional investment.
