Circle Interactive is a small, friendly digital agency based at the Create Centre at the foot of the Avon Gorge in Bristol. We’ve been solving online challenges since the birth of the web. We specialise in developing complex integrated systems using Drupal, Wordpress and CiviCRM, including Intranets, extranets, e-commerce and full back-office CRMs.
We prefer open source software as the base for developing our web applications. That's not just because generally speaking it's FREE: usually open source software is more robust and secure than proprietary alternatives.
Drupal is a mature project with thousands of contributed modules to extend the functionality of the core software. It also has a large and active community of developers around the world. Because of the well documented infrastructure, it's easier for us to extend.
CiviCRM is web-based, open source, Constituent Relationship Management (CRM) software geared towards meeting the needs of non-profit and other civic-sector organizations. It offers a complete suite of communications tools, allowing you to build subscriber lists and create effective mass mailings.
