Why insight matters for strategic consulting in the UK
For boards, private-equity teams and strategy units, the UK remains a pivotal test market. Consumer behaviour shifts quickly, regulation evolves in real time, and competitors scale from London to the world almost overnight. Relying only on historic datasets or syndicated surveys is no longer enough. What you need is context (why something is happening, not just that it is) and foresight (how markets and regulators are likely to react).
An insight company that blends rigorous analytics with qualitative depth can flag disruptive threats early and validate new growth bets before millions are committed.

These organisations excel at synthesising large datasets, building econometric models and packaging best-practice frameworks. When your question is broad—“Which markets should we enter next?”—or when you need global benchmarks at speed, they deliver.
Where traditional insight firms fall short
For ambiguous, frontier problems—think “How will GenAI reshape underwriting in the next 18 months?”—boards often discover that off-the-shelf analyses age instantly. Three recurring pain points appear: shelf-life (by the time a 150-slide report is approved internally, the facts have shifted), black-box assumptions (teams struggle to interrogate the underlying participant mix or analytical shortcuts hidden in proprietary models), and lack of nuance (quantitative averages bury the outlier insights that spark competitive advantage).
To fill those gaps, leaders increasingly turn to direct human expertise.
How Hiros stands apart
Hiros is purpose-built for strategy teams that need living, breathing knowledge, not static PDFs. Instead of selling pre-written market studies, we connect your consultants to hand-picked specialists—former regulators, ex-founders, senior operators—who have solved the exact issue you face. A 60-minute call with a former NHS procurement lead, for instance, can slash weeks off a med-tech go-to-market plan.
Ready to complement your existing insight stack with on-demand specialist calls? Visit our page designed for consulting teams to see how quickly you can brief, schedule and learn from the right expert.
Comparative advantages of expert conversations over market reports
Real-time relevance—you question assumptions live, dig deeper and pivot as fresh angles emerge; confidential specificity—you discuss sensitive, company-level scenarios without breaching compliance rules; and faster iteration—feedback loops compress from months to hours, allowing agile strategy sprints.
Cost efficiency follows. While a bespoke market study can run to six figures, an expert-call programme often delivers sharper direction for a fraction of that budget (pricing varies by expert seniority and call length; speak with us for indicative ranges).
