Our History

Cartesian is a specialist consulting firm in the telecommunications, media, and technology sector. Offering insight and advice, management and expertise, and solutions and technology, we help transform the products, services and organizations that ultimately shape these industries. We’ve been in this business for over 30 years. As the industries we serve have evolved during this time, so have we.

Cartesian Origins

The name Cartesian signifies intelligent and creative thinking, imaginative problem solving, and technical expertise from its origins relating to the French philosopher and mathematician René Descartes.

Founded in 1990 by a team of telecom engineers, Cartesian began life as The Management Network Group (TMNG). Initially, we provided management consulting services including business process transformation, marketing, and enterprise architecture to local US telecommunications and cable companies.

In early 2007, TMNG acquired UK-based consultancy Cartesian Limited. Based in London, Cartesian was a specialist TMT software engineering and consulting firm. Similar to TMNG, Cartesian was founded by a small group of telecom specialists whose aim was to deliver data-driven approaches to solve the challenges faced by communications service providers. The firm had also developed Ascertain®, a proprietary software product suite for revenue assurance, mediation, service activation, and data management for communications service providers. Ascertain has since evolved and serves as the platform for many of our advanced analytics and managed solutions.

Up until early 2014, our company operated under the brands “CSMG”, “Cartesian” and “TMNG Global”. In late 2013, we merged our business units and rebranded under one name, “Cartesian”. The new company brand was launched in February 2014. Later, in June 2014, updated our corporate name to “Cartesian, Incorporated”.

Company expansion

Cartesian has grown both organically and through the acquisition of other specialist firms in our industry. The common thread is our continued focus on the telecommunications, media, and technology sector.

  • 2001 – Cambridge Strategic Management Group (CSMG): added strategy advisory services
