Organisational Change & Capability Scaling
Building the leadership bench, culture systems, and change-ownership model an organisation needs to scale, integrate, or come through hypergrowth without the culture curdling.
What this covers
M&A integration and post-acquisition leadership restructuring
Culture reinforcement during rapid hiring or hypergrowth
Second-line leadership bench-building, so growth isn't capped by who's ready to lead

Inside the work
Real engagements, the constraint, the intervention, and what changed.
Fortis Investment Management Australia (FIMAL) → BNP Paribas
Alignment SystemConstraint
Under a global corporate transaction, FIMAL's European parent was acquired by BNP Paribas. With $4.3B in local assets under management across individually managed accounts, the APAC restructure carried extremely complex and sensitive strategic and operational stakes, and two earlier attempts to lead the integration had already failed before Stuart was called in.
Intervention
Brought in as the fixer after two prior attempts had stalled, Stuart took over the restructure and led the APAC region integration program end-to-end through the M&A, resolving leadership and operating-structure issues across the newly combined organisation on multiple fronts simultaneously, not the single workstream that had failed twice before.
Outcomes
- Succeeded where two earlier attempts had failed, the $4.3B AUM APAC integration led through to completion
- Strategic and operational continuity maintained across multiple fronts through a highly sensitive restructure
- Individually managed accounts transitioned without disruption to service
- Earned a lasting reputation inside the organisation as "the Fixer", the person called in when an integration was already failing, not just when it started
Healthcare scale-up · ~$60M
Confidential engagementConstraint
Rapid hiring had roughly doubled headcount inside eighteen months, and the culture hadn't kept pace, what got rewarded in practice (speed, individual heroics) quietly contradicted what leadership said mattered (collaboration, sustainable pace). Regretted attrition was climbing fastest in the teams the business could least afford to lose, and exit conversations kept naming the same gap: what was said and what was actually lived didn't match.
Intervention
Activated a cultural reinforcement system rather than another values poster, translated the stated values into specific, observable behaviours, built them directly into how every manager ran recognition and performance conversations, and made the gap between what the organisation said it valued and what it actually rewarded visible and correctable in real time.
Outcomes
- A culture the team is proud of again, not just words on a wall
- Regretted attrition in critical teams fell
- What gets rewarded finally matches what's said
High-growth firm · culture reset
Confidential engagementConstraint
Rapid growth had built a culture that looked high-performing on paper but was quietly toxic in practice, attrition in critical teams was climbing toward a quarter of the team each year, and burnout was becoming normal.
Intervention
Activated a cultural reinforcement system, redefining what actually got rewarded and recognised, applied consistently by every manager, so the stated values and the lived experience matched again.
Outcomes
- Annual attrition in critical teams dropped from 23% to 11% in 12 months
- Employee engagement/eNPS increased by 21 points within 9 months
- Burnout-related absenteeism reduced by 19% over 12 months
International Telco · multi-team
Confidential engagementConstraint
Change kept living in the PMO instead of the business, this wasn't the first attempt: new processes and systems had already been rolled out more than once without sticking, adoption stalling below 60% each time, with every relaunch meaning the same work redone from scratch.
Intervention
Rather than run a fourth identical rollout, installed a common leadership language and toolset owned by the leaders themselves, not the program office, fixing the ownership problem, the process problem, and the habit problem together.
Outcomes
- Adoption of new processes and systems rose from 57% to 86% in 6 months, this time, it actually stuck
- Rework due to poor adoption decreased by 33% within 9 months
- Stakeholder satisfaction with change delivery improved by 19 points over 12 months
PE-backed SaaS · ~$120M · 180 leaders
Confidential engagementConstraint
Headcount had doubled in 18 months but the leadership bench hadn't kept pace, every promotion was a gamble, strong individual performers were promoted into management with no real preparation, and the founder was the ceiling on every decision.
Intervention
Installed embedded development pathways with a defined capability standard at every level, coaching new and existing managers through the real moments of leading rather than handing them theory.
Outcomes
- Internal promotion into leadership roles increased from 34% to 67% in 12 months
- Voluntary turnover among emerging leaders fell by 22% over 9 months
- Average leadership effectiveness scores (360 feedback) improved by 13 points in 12 months
Multi-team leadership cohort · behaviour sustainment
Confidential engagementConstraint
Leaders had already been through a development program that left real insight, but it hadn't survived contact with the day job. Six months on, most had quietly reverted to old habits, and the program itself was being written off as another one that didn't work.
Intervention
Stepped in once the original program was written off, and built a sustainment system around it instead of running more training, reinforcing new habits, team rhythm, and manager follow-through together, through the moments that actually mattered.
Outcomes
- 78% of leaders consistently demonstrated the targeted new behaviours 6 months after the program, where the standalone program alone hadn't been enough
- Teams led by program participants saw engagement scores rise by 16 points in 9 months
- Delivery reliability and customer satisfaction improved by 12-14% over 12 months
