Who We Are
Resonance Leadership Advisory
We don’t sell theory or create external dependency.
We help you build what most people only teach – and, in the process, elevate strategy, leadership and culture in the flow of real work.
David is an engaging leadership facilitator and coach. I have definitely seen an improvement in my presence and have better understanding of how I can interact better with my team and other key stakeholders.
The content David delivers on cultural transformation and leadership development is real and relevant. As I step into a new Executive leadership role, David’s guidance has proved really valuable for me.

Over a 20-year career, David has reported to international banking CEOs, led the sales team behind a 10x rise in global investment sales at Standard Bank, built award-winning investment propositions, and coached world champion athletes and multinational CEOs. Today he brings that commercial rigour to every SCL Accelerator - fusing Google's leadership blueprint (learned directly from their Chief Learning Officer) with an evidence-based business school approach. His flagship course at Henley Business School is rated 9.7/10.
Alongside Resonance, David is an associate facilitator with leading business schools and training providers, an executive coach for CEOs and senior leaders at inflexion points, and a Penguin-published investment author. He holds top-tier qualifications across banking and investments, and is an MBA candidate with Henley Business School.

Adam Gottlich
Head of Behavioural Science & Impact Measurement
Adam Gottlich is Resonance's Immersion Architect and Impact Measurement Lead - responsible for designing the experiential learning sequences inside every SCL Accelerator, and for the diagnostics, behaviour-shift tracking, and ROI measurement that make the methodology defensible to ExCo.
An award-winning applied behavioural scientist, Adam brings 10+ years of experience helping financial firms improve decisions, innovation, and customer experience through behavioural science, predictive analytics, and decision architecture.
Adam is also the founder of Nudge Labs. Previously, he was Executive Head of Behavioural Science at Standard Bank Group, where he built the bank's behavioural science capability - driving measurable growth, trust, and customer journey improvements.
He holds an Honours in Cognitive Psychology (Wits, Cum Laude) and lectures in Applied Behavioural Science at Henley Business School.
His work is grounded in a simple belief: great outcomes are the result of disciplined science, not guesswork. And if you can't measure impact, it probably isn't worth doing.
