Company Profile

IntelliSoftware Ltd was founded in 1998 to develop innovative software solutions for business users. Specialisation in mobile messaging solutions began in 1999 leading to the launch of our first standard SMS product. This was quickly followed by hosted SMS internet gateway services in 2001. IntelliSoftware has enjoyed rapid growth and has a well established client base in the UK and overseas, achieving significant export sales to Europe and Asia Pacific region. Examples of blue chip companies that use our services include Hewlett Packard, Ericisson, Vodafone (Albania), Capita, Lastminute.com, Microsoft and AMP.

Intellisoftware is a customer focused and agile organisation, allowing us to work with organisations of all sizes in both the public and private sectors. We continue to innovate in the mobile messaging arena and we welcome feedback from all customers so as to continue to provide solutions that solve real business problems.

Service Architecture

The IntelliSoftware gateway utilises two redundant service nodes (www.intellisoftware.co.uk and www.intellisoftware2.co.uk, please see diagram below). The two service nodes are geographically separated ensuring the service is not susceptible to local internet outages. If a service node is unavailable, the IntelliSMS components automatically route to the available server. We maintain connections with multiple UK SMS operators, allowing us to send SMS traffic using the best performing route.
