Sigma Dos

What Sigma Dos does

Sigma Dos (legal entity SIGMADOS Análisis e Investigación, S.L.) is a Madrid-headquartered market research and demoscopic firm founded in 1982, positioning itself as the oldest continuously operating Spanish research and polling house. The company serves government institutions, political entities, media and publishers, private corporations, NGOs, and academic clients through a portfolio that includes custom market studies, sociological and electoral polling, communication consulting, and an academic diploma in political communication research delivered with Universidad de Salamanca and El Mundo. Its flagship contractual assets include the monthly El Mundo electoral barometer, the Forbes España Best Dircom ranking, and recurring engagements with CEIM, Banco de España, and Fundación IDIS.

The underlying technology stack combines classical demoscopic methodology (ISO 9001:2015 and ISO 20252 certified) with a proprietary TrustSurvey online panel that applies NLP and deep learning to open-ended responses and uses microsegmentation and geolocation for survey recommendation. The firm operates a CATI infrastructure exceeding 200 stations plus CAPI field deployment with 100 tablets, and runs the Sigma Dos 30' joint venture with Dos30' for monthly and quarterly streaming audience analytics covering Prime Video, Netflix, Disney+, HBO Max, and RTVE Play. An internal R&D department collaborates with universities and sector experts, while the IT department handles programming, statistical analysis, and system architecture.

The business model is primarily project-based B2B professional services (custom research, polling, communication consulting), supplemented by subscription revenue from Sigma Dos 30' VOD analytics and TrustSurvey panel monetization. Sigma Dos is a subsidiary of Eurostar Mediagroup, the Spanish member of Gallup International, and a founding member of CIMA with additional affiliations to Insights Analytics and Euroskopia. Pricing for professional services is quote-based and not publicly disclosed; the academic diploma is listed at EUR 3,465 for 38.5 ECTS credits, while panelist participation is free with Sigcoins-based rewards. GTM is sales-led and direct, with a complementary self-serve panel onboarding via web, iOS, and Android.
