Commercial leaders
with CXO experience and battle scars
Experienced executives who quickly understand the business, the people and the operational reality, and move fast from assessment to focused execution.
John Illerup Mortensen
I help companies turn commercial ambition into profitable growth.
Strong B2B businesses have repeatedly brought me in to change their commercial trajectory. I step back far enough to see the pattern and step in close enough to own the outcome. I have built my track record through commercial and people leadership, full P&L and customer-facing roles across corporates, SMEs and scale-ups.

Commercial leadership
with a proven change management toolkit
Most transformations stall on the people side. The Prosci certification gives a Wingman a structured, research-based method for leading people through change in day-to-day execution, combined with hands-on commercial leadership experience. Our ambition is for every Wingman to be certified.
More Wingmen joining the formation
The ambition is a curated group of senior commercial executives, united in Executive Collective, so each initiative is matched with the right battle scars.
