What GESS does
GESS Gesellschaft für Software in der Sozialforschung mbH is a Hamburg-based, privately held software and services firm founded in 1991 that specializes in market and social research. The company operates through two sister entities — GESS Software (product development and licensing) and GESS Phone & Field Marktforschung GmbH (field services and CATI operations) — and is led by founders Knut Holzscheck and Christian Janotta alongside managing directors Uwe Stüve, Stephan Struck, and Andreas Kroll. GESS serves research institutions, German federal and state government agencies, media research consortia, and commercial market research institutes with both software and full-service survey execution. Core customers include the Institut für Arbeitsmarkt- und Berufsforschung (IAB-Betriebspanel), the Bundesministerium für Bildung und Forschung (Adult Education Survey via Kantar Public), the Bundesverkehrsministerium (Mobilität in Deutschland via infas), agma (MA Print / Medientagebuch), and corporate accounts such as Hamburger Sparkasse AG.
The technology backbone is the "GESS Produktionsstraße" (production line), an integrated suite of four proprietary products: GESStabs (tabulation and statistical analysis with syntax-based scripting and 100+ statistical measures), GESS Q. (questionnaire programming and survey execution for online, offline CAPI on Android/Windows, and mixed-mode designs, with a January 2026 integration of ReDem's AI-powered quality scoring), GESS Cati (browser-based CATI management with open API and dialer integrations for Elsbeth and Authensis), and GESS ChartFactory (automated PowerPoint chart generation from tabulation outputs). All products are documented in German, English, and French and adhere to ISO 27001, ISO 9001, and ISO 20252 standards; the company is a corporate member of BVM and ADM.
GESS monetizes through a hybrid revenue model combining proprietary software licensing (the GESS production line) and professional services — telephone surveys from an in-house Hamburg-Eimsbüttel CATI studio of approximately 100 workstations and ~190 interviewers, online and offline surveys, mixed-mode design, and data processing and analysis. The go-to-market is direct sales from Hamburg supplemented by content marketing via the company blog and webinars, presence at industry conferences (BVM Kongress, Research & Results, WIN/GALLUP), and a self-serve support portal with training and documentation. The company has approximately 40 core employees (IT, software development, sociology, market and social research) and discloses no external funding, parent company, or institutional investors.

GESS product offering
Product offeringCore offering
GESS provides an integrated survey software suite and market research services for the entire research production line, from questionnaire design and data collection (online, offline, mobile, telephone) through tabulation and statistical analysis to automated PowerPoint charting. Its four core products — GESS Q., GESS Cati, GESStabs, and GESS ChartFactory — work together as a unified workflow, complemented by full-service field research delivered through its own 100-workstation CATI studio in Hamburg.
Product overview
GESS operates as a software-and-services company offering the 'GESS Produktionsstraße' (GESS Production Line) — an integrated suite of four complementary software products covering the full survey research lifecycle. The core software portfolio consists of: GESS Q. (questionnaire programming and survey execution platform for online, offline, and mixed-mode surveys), GESS Cati (browser-based CATI management software for telephone surveys), GESStabs (tabulation and data analysis software — the original product since 1991), and GESS ChartFactory (PowerPoint chart automation add-on to GESStabs). An Android/Windows CAPI module extends GESS Q. for offline mobile surveys. All four products are designed to work together in a unified production workflow: data collected via GESS Q. or GESS Cati flows into GESStabs for tabulation and analysis, with GESS ChartFactory then automatically generating presentation-ready PowerPoint charts. GESS also provides full-service market research survey and analysis services using its own software, covering telephone surveys in its own Hamburg CATI studio, online surveys, offline tablet surveys, Mixed-Mode designs, and data processing and analysis.

GESS competitors and assessment
Company assessmentBroad incumbents
- Ipsos: Global market research firm with significant digital data collection, proprietary platforms, and mixed-mode survey operations. Comparable to GESS in end-to-end survey research delivery, but operating at much larger international scale and with broader service lines.
- SurveyMonkey: Large-scale survey platform expanding aggressively into market research use cases with enterprise tier, panel partnerships, and analytics. Comparable in core survey software functionality but serves a much broader customer base beyond market research.
- NielsenIQ (formerly GfK): German-rooted global consumer panel and market research firm offering proprietary analytics, consumer panels, and survey-based intelligence. Comparable as a German-origin market research incumbent combining software, panels, and analytics.
- Kantar: Global market research giant operating proprietary software, panels, and fieldwork operations across 90+ markets. Comparable in offering end-to-end research services plus proprietary technology, but at vastly larger scale and with broader portfolio reach than GESS's German-focused stack.
Direct peers
- Qualtrics: Major enterprise survey and experience management platform with strong market research features including questionnaire design, multi-mode distribution, and analytics. Comparable to GESS Q. + GESStabs as a survey software platform serving market research use cases, though at much larger scale with broader enterprise focus.

Directly comparable as a research-specific software platform serving market research buyers with similar tabulation and reporting capabilities to GESS.

- infas Institut für angewandte Sozialwissenschaft: German social research institute that contracts GESS to conduct the online portion of the MiD study. Directly comparable as a German social-research field-services peer and existing client/partner of GESS, operating in the same federal research ecosystem.
- dimap: German market and political research institute headquartered in the same Hamburg Waterloohain competence center as GESS, with whom GESS collaborates on the SWR online election portal.
