Behaviour change that shows up in the numbers.
KM Studio is an experiment-led behavioural design consultancy. People, and organisations, rarely do what they intend to do. We close that gap: building behavioural science into the design of products, services and the teams behind them, and validating every intervention with live experiments in market. Behaviour change you can measure, not hope for.

Behavioural Science
We diagnose why people don't act, then engineer evidence-based interventions to change it. Grounded in established models and validated through live experiments, so the shift is real and measurable, not theoretical.

Live in-market experiments
Behavioural diagnostics
Longitudinal & Cross-market studies
Behavioural Science

Research & Insights
Large-scale, multi-method research that decodes the psychological drivers behind real behaviour. We pair qualitative depth with quantitative scale to surface the opportunities your competitors miss, then turn them into a clear roadmap.

Service Design
We map the complex journeys and operations behind your product, then realign the organisation to deliver them. Scalable blueprints and operating models that make the right behaviour the easy behaviour, for customers and staff alike.

Through flexible engagements built around your problem: one-hour problem-framing sessions, three-day sprints, time-boxed projects, and day-rate contracts, short, mid or long-term. We scope the smallest intervention that moves the metric.
Most design leans on intuition and best practice. We start from how people actually behave. Every recommendation is built on established behavioural science (COM-B, EAST, MINDSPACE, Fogg) and validated with real-world experiments, so you're not betting on opinion, you're acting on evidence. That's the difference between a redesign that looks good and one that changes the numbers.
We work across sectors and across the B2B and B2C divide, in both private and public environments (though more often private). From retail and financial services to health, tech, telco and travel, deliberately, because stress-testing behavioural methods across contexts is what makes them robust.
We take on a select number of projects to protect depth and quality. We're currently accepting engagements for H2 2026 and 2027. The earlier we talk, the better we can scope it.
