Ambrose and Bell
Advisory and execution for boards and leadership teams. Built around operator credibility, not methodology. Engagements scoped to defined outcomes.
The firm
Ambrose and Bell is an advisory and execution firm for boards, investors, and leadership teams. The firm works at the moments that decide value: growth transitions, operating model failures, leadership changes, commercial stalls, and transformation programmes that have lost their way. Six advisory engagements in three practice areas. Strategy and Operations: Operating Model Transformation, Transformation Programme Leadership. Technology and Digital: AI and Automation, Technology Product Leadership. Leadership Development: Leadership Team Assessment, Executive Coaching. Operator-in-the-seat engagements are delivered as Interim Leadership. Non-executive director appointments are governed under the firm's NED approach.
Ambrose and Bell is operator-led, drawing on a network of senior associates chosen to fit the work. Senior practitioners only, with no junior pyramid below the cover slide. The people who do the work are the people the client deals with, start to finish, and the aim is always to leave capability behind rather than create dependency on the firm.
Ambrose and Bell does not sell open-ended retainers. The firm delivers defined operating partnerships with milestone outcomes.
The firm works internationally, with engagements across the UK, Europe, and the US.
Five values. Each one shapes a real decision.
If a value isn't helping the firm make hard calls, it isn't a value. It's a slogan. These five constrain how the work is sold, run, and exited.
- Substance over signalling. We don't sell the slide, we sell the work. We say it plainly, even when it's uncomfortable.
- Words match actions. Track record is named to the prior employer who delivered it. The firm doesn't claim history it doesn't have.
- Respect for time and clarity. Defined milestone outcomes, not open-ended retainers. Engagement shape and investment scoped per engagement, with scope agreed before the work starts.
- Operator credibility. The capability is built on running businesses, not on owning a methodology. Work the firm names is work the principal has actually run.
- Clean exits. The leadership team must be able to operate without us when we leave. That is the test of whether the engagement worked.
Partner-led. Shape set by the problem.
An engagement is not a pyramid of associates with a partner on the cover slide. It is not a process bought off a shelf. Ambrose and Bell takes on advisory mandates, interim roles, and non-executive seats, scoped to a defined outcome or milestone. Shape is set by the problem. Every engagement is partner-led, with additional partners and specialists brought in by name where the brief requires it. Your leadership team stays in charge. We are paid to be useful, not present.
The operator behind the firm
Ambrose and Bell is led by Dr Stephen McCormac. Stephen has spent twenty-five years as an operator and adviser across services, consulting, technology, transformation, and outsourcing. Three statutory directorships. Engagements across European, North American, Indian, and Australian markets, in FTSE-100, Fortune-500, and German Mittelstand environments. Stephen is also an accredited executive coach (EMCC Senior Practitioner, Henley PCEC Level 7).
Stephen started his career as an engineer. He holds a doctorate from Stuttgart and spent two years at Robert Bosch on safety-critical automotive control systems, before moving into commercial and operating leadership. Fluent German, Irish passport, EU work rights. The pattern carries: trained to ship rigorously in environments where mistakes have real consequences, then took that into the seat where the P&L sits.
The work the firm sells is the work Stephen has run. Operating model design under live commercial pressure. Programmes brought back inside their controls. Subsidiaries turned. Leadership teams rebuilt. The full record sits on the engagements page.
The work, by theme.
Global and European transformations. ERP, AI and automation programmes. Turnarounds at subsidiary, programme, and working-capital level.
