Every leader remembers the moment the ground shifted beneath them — the day they stopped managing a single team and started leading other leaders. It’s a transition that looks straightforward on an org chart and feels anything but in real life. Few people have spent as much time studying that exact moment of change as Ian Lees, an Australian leadership coach and author whose work has quietly shaped how a generation of senior leaders think about growth, identity, and influence.
This article looks at who Ian Lees is, what he has built, and why his approach to leadership development continues to resonate with executives across the private, public, and not-for-profit sectors.
Early Career and the Making of a Coach
Long before Ian Lees became known as an author, he built his reputation the way most respected coaches do: in the room, working directly with leaders wrestling with real decisions. His coaching practice grew out of a simple observation, repeated across dozens of organisations — the skills that make someone an excellent individual contributor or team leader are rarely the same skills needed to lead other leaders.
Rather than treating leadership development as a checklist of competencies, Lees approached it as a question of identity: how leaders see themselves, how that self-image shapes their decisions, and how it either expands or limits the impact they can have. That grounding in what’s often called an “ontological” view of leadership — focused on a person’s way of being, not just their behaviours — became the foundation of everything he later built.
Key Contributions: Optimal Future and “Becoming a Leader of Leaders”
Today, Ian Lees is best known as the lead coach at Optimal Future, a specialist coaching practice built around a straightforward mission: helping leaders create the best possible future for themselves, their teams, and their organisations. Through Optimal Future, he works with senior, emerging, and high-potential leaders who are stepping into bigger, more complex roles and need to lead with clarity rather than simply survive the transition.
His most visible contribution to the field is his book, Becoming a Leader of Leaders: How to Succeed in Bigger Jobs and Still Have a Life. The book distils years of coaching conversations into a practical guide for one of the most demanding transitions in any career — moving from leading a team to leading other leaders. Rather than offering generic management theory, it walks readers through recognisable, relatable scenarios: the newly promoted manager drowning in two ringing phones, the brilliant engineer suddenly responsible for sixty people, the team lead who has the new title but hasn’t yet given herself permission, mentally, to own the bigger role.
A few of the ideas at the heart of the book include:
- Managing yourself in the moment so that decisions come from clarity rather than reactivity.
- Giving yourself the promotion in your own head before the organisation fully catches up with it.
- Creating space for the leaders who report to you so they can actually lead, rather than waiting to be told what to do.
- Integrating your team’s work with the wider organisation, so both stay relevant as circumstances change.
The book has drawn praise from senior figures in leadership development and academia, including a Deputy Vice-Chancellor at the University of Wollongong, who described it as a practical, self-reflective guide to one of the toughest transitions leaders face. Coaching and organisational development professionals at large government agencies and international banks have echoed that view, praising the book’s combination of real-world examples with deeper theory.
Public Profile: A Coach Known for Substance Over Style
Ian Lees has built his public profile the old-fashioned way — through the quality of his work rather than self-promotion. His writing on the Optimal Future leadership blog covers themes that go well beyond generic management advice: the psychological weight of leadership transitions, the fear many leaders feel presenting to senior executives, the discipline required to stay calm and effective in the moment, and the often-overlooked emotional toll of scaling a role from a handful of direct reports to dozens.
He has also lent his experience to other coaching organisations, including as the lead voice behind coaching methodologies built on ontological principles — approaches that treat personal growth and professional development as two sides of the same coin, rather than separate tracks. This reputation for depth, rather than quick fixes, has made him a trusted voice for organisations trying to prepare their next generation of senior leaders for genuinely bigger jobs, not just bigger titles.
Common Mistakes Leaders Make (In Lees’s View)
Drawing on the patterns highlighted throughout his coaching work and writing, a few recurring mistakes stand out:
- Continuing to solve problems directly instead of building the judgement of the leaders who now report to you.
- Waiting for a new title to feel earned rather than actively stepping into the identity of the bigger role.
- Underestimating the emotional difficulty of the transition, treating it as purely technical or logistical.
- Failing to integrate the team’s work with the broader organisation, which leaves both increasingly disconnected over time.
Current Activities (2026)
As of 2026, Ian Lees continues to lead coaching engagements through Optimal Future, working with leaders across complex organisations who are navigating exactly the kind of transition his book addresses. His coaching philosophy — rooted in self-awareness, sustainable performance, and genuine influence rather than control — remains just as relevant in a workplace still adjusting to hybrid work, generational change, and rising expectations of senior leaders. New coaching clients continue to receive his book as a companion to their sessions, reflecting how closely his writing and his day-to-day coaching practice are intertwined.
Looking Ahead
The demand for thoughtful, identity-based leadership coaching shows no sign of slowing down. As organisations flatten their structures and push accountability further down the chain, more professionals will find themselves thrust into “leader of leaders” roles earlier in their careers — often with less preparation than the moment deserves. Coaches like Ian Lees, who focus on the internal shift required alongside the external skills, are likely to remain in demand precisely because that gap between title and readiness isn’t closing anytime soon.
Conclusion
Ian Lees represents a particular kind of leadership expert — one who has resisted the temptation to reduce leadership development to slogans or quick frameworks. Through his coaching practice at Optimal Future and his book Becoming a Leader of Leaders, he has offered a grounded, human alternative: help people become who they need to be, and the skills tend to follow. For anyone standing at the edge of a bigger job and wondering if they’re ready, his work offers a reassuring message — readiness isn’t something you wait for. It’s something you build, deliberately, one honest conversation at a time.
