Market studies: Psychologically audit your competitors
& consumers to decode what works
You're launching a new product, entering a market, pivoting your offer? You can't settle for a classic market study — catchment areas, superficial SWOT, sector growth figures. What you really need to understand is why some offers work and others fail. What are the psychological drivers that make a consumer buy from your competitor and not elsewhere? What real needs (not declarative) does your market express? What paths remain unexplored by the competition?
Our Psychologists, Sociologists, Behavioral Economists & Strategists conduct strategic market studies: psychological audit of competing offers (why they work, their hidden flaws), analysis of real economic models (viability vs storytelling), identification of deep consumer needs (behavioral economics, not focus groups), and spotting blind spots — the paths no one has exploited yet. You don't just map the market, you understand its mechanisms and identify where to strike.
Market research & internationalisation
Audit the psychological drivers of competing offers
Why does your competitor's offer work? Is it the price, the messaging, the positioning, the trust mechanism? We conduct an in-depth psychological audit of offers present in the market: analysis of adoption levers (what triggers the purchase?), identification of hidden flaws (where competitors fail without knowing it), decoding of real economic models (viability vs marketing storytelling). You understand what truly works, not what competitors claim.
Identify unexplored paths & Real needs
What consumer needs remain unserved? What paths has the market not yet seen? We use behavioral economics and user psychology to reveal deep needs (not the declarative from focus groups) and spot the competition's blind spots. Trade-off tests, iconic tests, field observations: you know where to strike before your competitors, and you build an offer that responds to real needs, not declared intentions.
Test & Simulate before market launch
Before investing massively, test your hypotheses. We simulate consumer behaviors under realistic conditions: trade-off tests (which product do they really choose?), iconic tests (which visual identity has impact?), controlled experiments (which commercial messaging triggers purchase?). You validate what works before launching, you avoid costly mistakes, you iterate until you find the winning offer.
Internationalization: Audit drivers abroad
You want to expand internationally? Mechanisms that work in France don't necessarily work elsewhere. We conduct multi-zone field studies (Europe, United States, Asia, Middle East) to understand cultural drivers, local adoption levers, effective commercial messaging per market. You don't copy-paste your French offer, you adapt it to the real needs of each territory.
Reframe your commercial messaging to resonate
Your offer may be excellent, but if your commercial messaging doesn't tap into your targets' psychological drivers, you won't have customers. We analyze how your consumers actually think: which words trigger interest, which promises create trust, which cognitive biases activate purchase. Through behavioral economics and semantic analysis, we reframe your commercial messaging to resonate with your targets' deep motivations — not what they claim to want. Ad message testing, analysis of effective competitor messaging, identification of emotional and rational levers: your communication becomes an acquisition lever, not just a storefront.
Our expertise for market studies
Far beyond providing you with data, we support you with a qualitative and quantitative approach that mobilizes Psychology, Sociology, Behavioral Economics, and Strategy to decode the real behavioral mechanics of your users or target customers. A team of experts with degrees in Human Sciences conducts field studies, psychological audits of competing offers, controlled experiments, and strategic modeling for your business plan.
You benefit from reliable advice and guidance, based on robust analyses drawn from scientific research. Our role is to help you establish your strategy through proven methods: academic literature reviews, trade-off tests to reveal real preferences, iconic tests to identify what has impact, ethnographic field observations, cognitive modeling of purchase decisions, and advanced statistical analyses (PCA, CA, SEMs). You rationally evaluate your project's viability, its fit with consumers' deep needs, and the relevance of your positioning — not on intuitions, on evidence.
We mobilize several collection and exploitation techniques from Human Sciences and Behavioral Economics: documentary studies to capitalize on existing knowledge, field surveys to understand real usage, scientific experiments to isolate causalities, statistical analyses to quantify determining levers. You have specialists in Psychology, Sociology, Behavioral Economics, Strategy, and — if necessary — in communication and design to transform your findings into an operational offer. Support until your project's realization.
Nous vous fournissons plus que des données : une conviction
1Get away from quantitative market research
The majority of studies available on the market are quantitative studies that simply describe, in percentage terms, behaviours that you already suspected: "people tend to buy bread before meals and cakes at the weekend". It's not very useful.
2Forgez-vous une conviction
What you really need is not numbers: you need to understand the user mechanics to know whether or not you can be of service to them. They will only buy from you if your service is real, useful and usable.
3Our method
Our psychologists, sociologists and marketing experts are human science specialists who will carry out field studies and prototype studies to anticipate whether or not your product connects with users' needs. In this way, you can form your own convictions and pivot if necessary.
We can help you make sense of your market research
If you want to launch an innovative service, set up your own shop or diversify,
