01
Speed to impact
Engaged in weeks, not months. I learn the culture, the goals, and what is already being tracked. Then I move: follow the revenue, follow the loss, find where the risk sits. Mitigation options come with urgency.
PRAXIS kar
CxO · Board Director · Advisory Services
C-suite leadership from strategy to execution.
P&L · Operations · Client and Stakeholder Outcomes
Twenty-five years of executive accountability across IBM, HP, Bell Canada, Siemens, Huawei, and Inuvika. COO and fractional CxO mandates for boards, founders, and investors who need hands-on transformation leadership and fast results. Engaged permanently, on interim, or fractionally, depending on what the mandate calls for.
Principal
The engagement model, and why it works.
Senior operating capability, applied to a defined mission with clear KPIs and an agreed runway. The right engagement structure depends on the organisation and the moment. The six ways to work together are set out below. What does not change across any of them is the standard: measurable outcomes, delivered quickly, with full accountability for results.
02
Operator, not advisor
I take the wheel. Decisions get made, plans get executed, results get reported. Boards and investors see traction in the first quarter, not the third.
03
Objective, outside-in lens
Not entangled in internal politics or legacy decisions. I name what is not working, protect what is, and challenge the board with the candour an internal executive often cannot provide.
04
Accountable to outcomes
Accountable to KPIs, not headcount. Every engagement is structured around what gets delivered, not how many days are billed. That alignment changes how the work gets done.
Leadership Calibrated
Senior leadership, calibrated to the moment.
Founders, boards, and investors engage me when the stakes are high, the runway is finite, and the wrong hire costs more than the right outcome. The preferred outcome is a permanent executive seat. Where the mandate is shorter or sharper, an interim or fractional structure gets the same work done.
01
Align operations to the business
Strategy is only as good as the playbook beneath it. I align operating models, KPIs, and execution cadence to the business objectives, co-authored with the leadership team and backed by every major stakeholder, so the plan actually gets run.
02
Operator first, advisor second
I take the wheel. Decisions get made, plans get executed, KPIs get reported. Boards and investors see traction within the first quarter.
03
Cultural fluency
Lived and operated across the UK, EU, GCC, APAC, and North America. Regulatory pattern recognition, boardroom etiquette, and partner networks on four continents, translated into results on the ground.
04
Investor-grade discipline

I don't hand over recommendations and walk away. I sit at the table, make the call, and stay accountable for the result.
01. Engagement Structures
Six ways to engage.
The right structure depends on what your organisation needs and how quickly you need it. Three paths suit a permanent or extended mandate. Three suit a defined scope with a fixed end point.
01
Permanent CxO
A full executive seat. P&L accountability, team leadership, and board-level governance. For organisations that need a seasoned operator in the chair, not an advisor at the edge of the table.
02
Interim Executive
Deployed into a leadership gap during transition, restructuring, or search. Immediate traction, no ramp-up cost, and a clean handover when the permanent appointment is made.
03
Fractional COO / CTO / CIO
Retained engagement, part-time presence, full executive accountability. Strategy, delivery governance, vendor oversight, and commercial rigour applied to a defined mandate, without the overhead of a permanent hire.
04
Transformation Programme Lead
End-to-end ownership of a complex initiative: ERP migration, OSS/BSS redesign, operating model change, or post-merger integration. Programme leadership with commercial discipline at every stage.
05
Practice & Delivery Leadership
Build, stabilise, or scale a consulting or professional services function. Margin recovery, SLA governance, contract restructuring, and the operating cadence that keeps a services business profitable.
06
Market Entry and Commercial Advisory
GTM strategy, partner ecosystem development, and commercial structuring for a new geography or vertical. Grounded in direct operating experience across Canada, the UK, GCC, APAC, and EMEA.
