What Cartesian does

Cartesian is a specialist professional services firm that has served the global telecommunications, media, and technology (TMT) industries for over 35 years, operating from offices in London (Shoreditch High Street, EMEA headquarters) and Boston with approximately 100 consultants supported by 251-500 total employees. The firm delivers six interconnected service lines — Analytics & Data Science, Strategy Consulting, Management Consulting, Technical Services, Technology Solutions, and Content Security — addressing network transformation, fiber deployment, business assurance, MVNO strategy, video platform deployment, and commercial/technical due diligence for tier-1 carriers, major European operators, broadcasters, ISPs, MVNOs, and private equity clients.

The firm's technology stack is anchored by the proprietary Ascertain® managed analytics platform, which integrates with client systems for near real-time business intelligence and revenue analytics. Additional proprietary assets include machine learning churn prediction models (decision trees, random forests, gradient boosting), geo-spatial clustering algorithms for streaming credential-sharing detection, an anechoic chamber and multi-story Wi-Fi test houses accessed through a University of Bristol partnership, and analytics tooling for network inventory mapping. Cartesian also produces industry-standard research products, including the State of US Broadband Report and the annual Fiber Deployment Cost Report published in partnership with the Fiber Broadband Association.

Cartesian monetizes primarily through fee-for-service consulting engagements, project-based pricing, and managed analytics subscriptions, targeting Fortune 1000 TMT enterprises and selected government/regulatory clients such as Ofcom. The firm operated as a private entity owned by Blackstreet Capital Holdings from prior to 2014, when it raised approximately $5.3M, through May 12, 2026, when it was acquired by AI services firm Bounteous. Post-acquisition, Cartesian continues under CEO Jim Serafin as part of a combined organization of more than 5,000 specialists focused on AI services, analytics, cloud, and experience design.
