Market Intelligence is what sets us apart and what defines us as a brand – literally in fact: when the company was founded in 1972 it took its name from an amalgamation of the two words. We have been defining and refining the Market Intelligence Mix ever since, to offer our clients a unique perspective on the consumer landscape ahead and a clear roadmap with which to navigate it. So what goes into the market intelligence mix? MARKET RESEARCH is not the only thing we do, but it is right at the core of our business. The vast range of primary research we carry out and commission is the bedrock of our market intelligence, creating data series we can assess incrementally over the long term to track trends and forecast the future. MARKET ANALYSIS is the second key element of the market intelligence mix. Our specialist team of market analysts scours the globe for trade, industry and government data, which our statisticians then integrate into meaningful sizing models and future value forecasts for thousands of sectors worldwide. PRODUCT INTELLIGENCE adds micro-level relevance to the macro context of our market analysis, bringing our clients real-world examples of the launches and goods that are driving the numbers. COMPETITIVE INTELLIGENCE is the fourth pillar of our work, keeping our clients abreast of their rivals’ strategies, communications and results, to give them the understanding they need to choose the right response to gain or maintain that crucial competitive edge. The magic happens when we pull them all together. Trend analysts, category specialists, systems developers, dedicated account teams and client servicing staff work together to provide our clients with understanding as well as knowledge. That’s our Market Intelligence. That’s how we help businesses grow. It’s why we’re the leaders in it.
