BTS is a global professional services firm that helps the world’s leading organizations move from strategy to execution at scale. Founded in 1986 in Stockholm by Henrik Ekelund, BTS was built on a simple belief: capability is built through experience. We were the first consulting firm to bring business simulations to market, placing leaders inside real decisions instead of just talking about them. Today, under the leadership of CEO Jessica Skon, BTS is focused on the next era of performance. AI is reshaping how work happens and how organizations create value. We help companies move beyond traditional top-down strategy execution by empowering teams at the front lines to innovate, experiment, and improve how work gets done, then align leadership to scale those breakthroughs across the enterprise. Our approach to consulting is hands-on, practical, and centered on co-creation in the flow of real work. We work side by side with leaders, test ideas in live environments, and build change directly into how the organization operates. • Strategy execution and business transformation • Immersive business simulations • Leader readiness and development • Executive and team coaching • Business acumen and mindset building • Go-to-market strategy and sales enablement • Talent assessment, succession, and workforce capability • AI activation, workflow redesign, and enterprise reinvention • Innovation strategy and capability building For nearly 40 years, BTS has been a trusted partner to more than 1,200 organizations worldwide, including over 40 of the world’s 100 largest global corporations.
