Will Jefferson & Lindi Smit

Founders & Directors

As co-leaders of Performance Catalyst, Will Jefferson and Lindi Smit bring together a powerful fusion of elite sports experience, leadership consulting, and deep insight into high-performing teams. Will Jefferson, Founder of Performance Catalyst, draws on a 12-year professional cricket career—playing at both County and International level—combined with his work as a trusted business and sport consultant. His passion for human performance and psychology underpins his approach, shaped by years of leading executive workshops for clients including Sainsbury’s, British Athletics, Deloitte, and HSBC’s Global Tax and Treasury teams. Will has worked extensively across the UK and internationally, supporting leaders and teams in Paris, Barcelona, Amsterdam, Lisbon, Vienna, Geneva, Hong Kong, Shanghai, Singapore, Dubai, and Mumbai. Known for his empathetic, one-to-one work and powerful group facilitation, Will empowers teams to unlock excellence through deeper connection, insight, and alignment.

Lindi Smit brings a rich blend of leadership, facilitation, and high-performance expertise from her career as both a team physiotherapist and elite netball player. As a former Netball Superleague team captain and international tour physiotherapist, she understands first-hand the mental and physical demands of elite team performance. Her experience spans diverse industries, where she’s facilitated growth and cohesion in both leadership teams and frontline groups. A licensed Insights Discovery Practitioner and Liberating Leadership facilitator, Lindi helps individuals and teams discover their unique strengths, communicate with clarity, and perform at their best.

Together, Will and Lindi lead with a shared belief: that truly high-performing teams are built on trust, alignment, and the understanding that we are stronger together. Through Performance Catalyst, they partner with organisations to create cultures of excellence through Clarity, Connection and truly tapping into the Collective Intelligence of teams.
