Be the change.
How agile are your people? We'll help you find out.

​
Learning agility, emotional intelligence, adaptability and interpersonal impact are some of the key skills differentiating talent in today's workforce. Knowing how to identify and accurately measure these capabilities when recruiting talent and developing an existing employee population is vital when it comes to future-proofing your organisation.
​
Is your assessment and development proposition relevant to today's shifting world of work? Past performance is no longer a predictor of future success. The pace and complexity of change mean what matters isn't what people know but rather how they learn, adapt and apply what they learn amidst adversity.
Today's business landscape no longer rewards just the fittest, but the fastest — those with the capacity to evolve, respond and innovate at speed. According McKinsey (2021), organisations achieved up to 30% gains in efficiency, customer satisfaction, employee engagement, and operational performance — becoming 5-10 times faster in decision making and significantly accelerating innovation. The first step in any agile transformation is the top team; where value creation windows are compressed and leadership missteps are costly — the quality of executive assessment is critical — and knowing who to hire and promote has never been more important.

Sarah Skinner, EVP EMEA & Global Business Strategy Advisor, Grace Blue
"As an executive search firm, we understand the importance of rigour and insight in how we assess candidates. When it comes to the deep dive leadership assessment using the blend of psychometrics and in person analysis, Marcelle is the only partner we use and recommend to our clients.
Her clarity, framework, approach and analysis are expertly blended to give incredibly perceptive and accurate insights into our candidates. She takes the time to understand the brief, the context, the requirements of the role. Every candidate who has worked with Marcelle speaks consistently of the outstanding experience, and every client can immediately see the value and perspective Marcelle brings in order for them to make an informed decision.
Marcelle always brings a strategic, informative and objective view point. And just as importantly is a joy to work with."
Julian Read, CEO, Doro Consumer Electronics
" Marcelle is a great support to me in my role as CEO. Our coaching sessions focus upon the challenges ahead and how to leverage my strengths whilst being mindful of the things that come less naturally to me. I always leave our discussions mindful of my own behaviours and observe those of others which enables me to be more effective in my role. Marcelle has also supported other managers in my business within a 360-degree feedback process followed up with one-to-one coaching. I would, without doubt, recommend Marcelle to any leader interested in personal development as a means to being more effective in their interactions with key stakeholders and for personal growth"
Honor Pollok, Founder & CEO Kynigos Partners
“ The Board and Chair of a well-established media company wanted a deep assessment of two exceptional final CEO candidates to supplement the search process, aid their decision-making process and support the on-boarding of the successful candidate. The quality and accuracy of Marcelle’s assessments were outstanding, providing the client with the additional data points needed to differentiate between the two candidates and aid the creation of an onboarding programme.
Professional, focused on meeting my client’s needs and highly responsive it was a pleasure to work with Marcelle. I would highly recommend her and will definitely work with her again. "
