What Stack Data Strategy does
Stack Data Strategy is a London-headquartered data-driven polling and research consultancy serving governments, political parties, corporations, and non-profit organizations across more than twenty countries. The firm was established as a private UK company (Stack Data Strategy Limited, Company no. 13336894) with corporate registration in London and a US subsidiary (Stack Data Strategy (US) Inc.) in Washington, D.C., operating with a headcount in the 11-50 range. Its service portfolio spans commissioned polling, Multi-level Regression and Post-stratification (MRP) modeling for constituency- and local-area-level vote intention forecasting, election campaign advisory, attitudinal segmentation, qualitative focus groups, quantitative survey research, data analytics and visualization, and bespoke Site Reports for planning and development clients; the firm has also launched a software product, 'strata', providing localized insight on attitudes to development.
The firm's core technology is its proprietary MRP methodology, which combines demographic and political variables to produce vote intention and public opinion estimates at granular geographies — down to constituency, local authority, and even UK Office for National Statistics Output Area levels — with per-prediction uncertainty estimates. The modeling pipeline is supplemented by segmentation techniques (latent class, k-means, PCA, factor, driver, and regression analysis) to identify persuadable attitudinal groups rather than relying solely on demographic clusters. Stack's published work has demonstrated accurate electoral forecasting in UK, US, and German elections, including sample sizes ranging from 500-respondent business leader surveys to 30,034-respondent multi-country studies.
The business model is project-based professional services: clients engage directly via the firm's website and [email protected] for bespoke research and advisory engagements, while a published omnibus ratecard supports standardized polling transactions. The firm is sales-led with senior advisor engagement; it has no public pricing, no institutional funding disclosure, and no parent company. Customers span political parties and think tanks (Shelter, Our Scottish Future, Onward, Centre for Social Justice, Make Votes Matter), media organizations (Sky News, The Economist, Politico), consumer and technology brands (BCG, Spotify, Deliveroo, Iwoca, Accurx, Multiverse), and charities (Save the Children, E3G, Trussell Trust, American Conservation Coalition Action). Marketing is content-led via blog, election notes, newsletter, LinkedIn, X, and earned media placements in The Times, Daily Mail, Politico, Sky News, and CityAM. The firm is a member of the British Polling Council.
