Founder, Mainwaring Search

Robert founded Mainwaring Search in 2002 after fifteen years in board practice at two global search companies.

Six people in London, deliberately. Robert holds the Board & NED chair in the first volume of The Executive Search Ten.

THE TWELVE

What Robert Mainwaring said.

01
What separates the executives who succeed from the ones who fail?

The first ninety days tell you, and almost nobody uses them properly. The ones who succeed spend that time listening and the ones who don’t spend it announcing.

You can predict a great deal from what they did in week three. I have started asking referees precisely that question, and the answers are wonderfully revealing.

02
AI is doing more of the work every year. What happens to the people you place?

At board level the work was never finding names. Everyone knows the names; there are only so many people who have chaired an audit committee through a restatement.

What the machines have done is make the research instant, which strips the mystique off my profession and quite right too. What is left is the part that was always the job: judgement, discretion, and telling a chairman something he does not want to hear.

03
What is the most overrated quality in a leader?

Presence. Boards fall for it repeatedly. The director who commands the room in the interview commands the room in every meeting thereafter, whether or not they have read the papers.

The most valuable director I know says one thing per meeting, and it is always the thing.

04
Is culture fit a real assessment, or an excuse?

At board level the honest word for it is collegiality, and it is both real and dangerous. A board must be able to work together; a board that enjoys working together too much stops asking each other difficult questions.

I have learned to worry when a nominations committee tells me everyone got on tremendously.

05
What kind of leader does a business need now that it did not five years ago?

Directors who understand technology as owners rather than tourists. Every board now has one presentation a year on AI; the boards that matter have someone who can ask the second question.

06
What do boards get wrong about succession?

Chairs run the succession of every role except their own. The average board can tell you who the next chief executive is and goes silent when you ask who the next chair is. It is the last taboo in governance, and it is where I make half my living.

07
Is the market for senior people rational?

The non-executive market is rational to a fault: it prices reputation, and reputation lags reality by about five years. People are appointed for what they were and removed for what they are.

08
When should a company not use a search firm?

When what the board needs is a conversation, not a candidate. A surprising number of searches are really a disagreement between the chair and the chief executive wearing a job specification as a disguise. The useful service is saying so.

09
Twenty years of diversity targets. What has actually changed at board level?

The non-executive numbers transformed, genuinely. The FTSE boardroom of 2006 and the one of 2026 are different rooms, and search played its part late but played it.

The executive pipeline is the unfinished half, and boards know it. The grid filled in; the corner office is taking longer.

10
How much of a leader’s success is the person, and how much the company they land in?

Sixty-forty the company, though at board level the ratios shift: a non-executive’s success is perhaps eighty per cent the board they join. The same director is wise on a good board and wallpaper on a bad one.

11
Who did you back when everyone else thought you were wrong?

A chair for a family business in crisis: retired, written off, twelve years out of an executive seat. Every adviser in the room wanted a name from the current lists.

He had seen the exact crisis twice before. The business is still in the family, which was the entire brief.

12
The question I wanted to be asked.

“What should a board be embarrassed about?”

How little time it spends on the only two decisions that are unambiguously its own: who runs the company, and who sits at the table. Everything else is oversight. Those two are the job.

THE QUICKFIRE TEN

Ten quick ones.

Asked at every sitting, answered without thinking too hard.

Phone call or email?A letter, if I could get away with it. The phone, since I can’t.
CV or LinkedIn?The CV, over lunch, with the person attached to it.
How long should a first interview last?Two hours. It is a marriage, not a transaction.
The most overused word in a job spec?Visionary.
Counter-offer: stay or go?Go, with a handwritten thank-you.
Best question a candidate ever asked you?“Who did this board last disagree with?”
Suits: still required?I am wearing one now and I was not planning to be photographed.
The reference that matters most?The chairman’s, given reluctantly.
Your industry in one word?Enduring.
The job you would never take?Chief executive of anything. I have watched three hundred of them; that is close enough.
