What it is

An operator in the seat, on a defined term

Some moments need a permanent hire. Others need a defined-term operator who can be in the seat in two to four weeks and hand over cleanly when the work is done. Ambrose and Bell takes interim CEO, MD, divisional MD, COO, and C-suite-minus-one engagements where the brief is operational rather than advisory. Industry agnostic: each seat is assessed on the shape of the work, not the sector label.

What it is not. It is not advisory, coaching, or retained consulting. The interim leader holds the seat and the decisions that go with it. The accountability holds for the whole term, and the handover happens at the end.

When to engage it

Six contexts where interim leadership earns its keep

Sudden leadership gap

A CEO, MD, or divisional leader has departed and the business cannot wait six months for executive search. Interim covers the seat while permanent recruitment runs in parallel.

Transformation as the lead, not the adviser

A funded transformation needs the person accountable for delivering it making the calls inside the business, not advising from alongside it.

Pre-acquisition stabilisation

The business needs to run like a serious operation before the deal closes. Interim brings the operating discipline a buyer underwrites.

Post-acquisition integration

Two businesses are becoming one and the integration cannot stall. Interim takes the integration P&L for the defined period it takes to bed in.

Founder transition

A founder is stepping up to chair or stepping away. Interim holds the operating seat while the permanent CEO or MD is appointed and inducted.

Board-mandated turnaround

The board wants an operator with no attachment to the strategy that produced the current position. Interim arrives with the independence to call it cleanly.

How we engage

90-day milestones, defined exit

Brief and shape

Role, milestones, exit criteria, and commercial shape agreed in writing before start. No surprises mid-engagement.

Two to four weeks to in-seat

From agreed brief to operating in the seat. Executive search takes four to nine months; the speed difference is the point.

90-day milestones

Engagement length banded in 90-day blocks with formal review at each. Either side can step away at a milestone.

In the business, not advising it

The interim holds the seat and the decisions. The team reports to them as they would to a permanent leader.

Clean exit

Handover is planned from day one. Documentation, relationships, and the operating rhythm pass to the permanent successor without a gap.

No equity, no kickers

Day rate or monthly fixed fee, paid in arrears. No performance bonuses, no equity, no post-exit consulting for twelve months by default.

Why operator-led matters

The seat is real, not consulting under another name

Search firms place interim executives. Ambrose and Bell takes the seat. The difference shows up in the work: decisions made the day they are needed, an accountable leader rather than a consultant on a project, a decision in the room rather than a recommendation in a deck.

Stephen brings twenty-five years of operating experience: four statutory directorships, and P&L accountability across MD and divisional roles in services, consulting, and technology businesses. The seat is held the way a permanent leader would hold it. The fixed exit is the only difference.

When the brief needs more than one pair of hands, Stephen draws on a network of senior associates chosen to fit the work. No junior pyramid, and the aim is to leave the leadership team able to run without us.

When it does not pay back

Five situations where interim leadership fails to land

Knowing these at the start saves both sides three months and a difficult exit.

The board has not decided what the interim is for

Without a brief and milestones written down at appointment, the engagement drifts into firefighting and the exit is messy. The fix: a written brief, milestoned in 90-day blocks, signed off on day one.

The brief is "fix the predecessor" rather than "fix the situation"

When the goal is undoing a predecessor's strategy, the engagement turns tribal. The team feels judged, decisions go political, and the handover breaks. Interim is for fixing the situation. It is not the place to settle scores.

The commercial structure includes equity or a performance kicker

Equity gives the interim a stake in an outcome they will not be there to see. Bonuses incentivise the wrong behaviours over a 90-day horizon. Day rate or monthly fixed fee, in arrears. Nothing else.

The leadership team treats the interim as a consultant

If the team sends decisions up for sign-off rather than running them, the interim becomes a bottleneck, not a leader. The seat has to be held, and treated, the way a permanent leader's would be.

The interim has never run a business

Career consultants bring frameworks and analysis, not the operating instincts of someone who has held real P&L accountability. For senior interim seats, the operator track record is the qualifier.
