What Founders Get Wrong When Briefing an Executive Search

A better brief doesn’t just save time – it changes the quality of the hire

---

Most founders approach an executive search the same way they’d approach any other procurement decision. They have a role to fill, they know roughly what they’re looking for, and they brief a search firm with a job description and a list of requirements. The search begins. Candidates are presented. A hire is made.

The problem is that this approach optimises for speed and activity rather than fit and outcome. And in senior leadership hiring – particularly in fast-scaling AI infrastructure, data, and cloud businesses where the margin for error is small – a weak brief is usually where a mis-hire begins.

After 15 years working on executive search in high-growth technology businesses, the same briefing mistakes appear time and again. Here’s what they are, and what to do instead.

Starting with the title rather than the problem

The most common mistake is beginning with an org chart rather than a business challenge. A founder decides the company needs a CRO, or a CPO, or a VP of Engineering, and frames the brief around that title – the seniority required, the team size, the reporting line.

What usually gets skipped is the harder question: what specific problem is this person being hired to solve?

That question has a different answer in every business, and the answer matters enormously for the type of leader you actually need. A CRO hired to build a repeatable enterprise sales motion from scratch is a fundamentally different person from a CRO hired to scale an existing team across new geographies. The title is the same. The role is not.

A brief that starts with the title will attract candidates who fit the shape. A brief that starts with the problem will surface candidates who can actually solve it.

Describing the ideal candidate rather than the ideal outcome

Closely related to the above is the tendency to build a brief around a candidate profile – years of experience, previous employers, educational background, technical skills – rather than around what success looks like once someone is in the role.

This matters because profile-led briefs create a filter that feels rigorous but often isn’t. They reward pedigree over capability, and they frequently exclude the best candidates for the actual role. In AI infrastructure businesses particularly, the leaders who perform best in complex, technically demanding commercial or operational roles often don’t come from the obvious backgrounds. They’ve built things from scratch at less well-known companies. They’ve navigated transitions that weren’t linear. They’ve developed deep sector fluency that doesn’t fit neatly into a CV summary.

Defining what success looks like at 6, 12, and 18 months is a far more useful exercise than defining what the ideal CV looks like. It also produces a much better brief.

Underestimating how specific the context is

AI infrastructure businesses are not generic technology companies. The sales motion is different. The buyer relationships are different. The product complexity is different. The organisational culture – typically technical, often founder-led, usually moving very fast – is different.

Founders sometimes brief a search as though any strong senior leader from a technology background could step in and perform. In practice, the context mismatch is one of the leading causes of early failure in senior hires. A leader who has spent their career in enterprise SaaS will approach an infrastructure sales organisation very differently from someone who has built and scaled a technical go-to-market in a similar business. Both might look strong on paper. Only one is likely to work.

A good brief conveys the specificity of the environment honestly – including the parts that are hard. The pace, the ambiguity, the founder’s continued involvement, the technical depth required to earn credibility internally. Sanitising the brief to make the role sound more appealing rarely ends well.

---

Treating the search firm as an order-taker

Many founders approach a search engagement as a relatively passive transaction. They provide the brief, and the search firm goes and finds people. Updates arrive. Candidates are reviewed. A hire is made.

This model produces mediocre outcomes, even with a good search firm. The best executive searches are collaborative. The founder’s insights about the business, the team, the competitive context, and the nuances of the role are essential inputs – not just at the briefing stage, but throughout the process.

More importantly, the most valuable thing a search partner can offer isn’t just access to candidates. It’s an honest, informed perspective on the market – on what’s realistic, what the competition is paying, what profile of leader is actually available, and whether the brief as written will attract the right people. That perspective is only useful if the relationship is open enough for it to be shared plainly.

If a search firm never pushes back on your brief, that’s not a sign they agree with you. It’s usually a sign they’re not adding much value.

---

Not thinking about what comes after the hire

The final briefing mistake is treating the search as complete when an offer is accepted. Most founders – and most search firms – move on at this point. The role is filled. The next priority takes over.

But in senior leadership hiring, the real risk sits in the first year. The quality of the brief determines not just who gets hired, but how well the business is set up to support that person once they join. Clarity on the mandate, the success criteria, the founder’s ongoing involvement, and the boundaries of the role are all things that should be established during the briefing process – not figured out after the hire starts.

Common points of failure that trace back to a weak brief:

• The new leader interprets the mandate differently from the founding team, and no one discovers this until significant damage is done
• Unrealistic timelines are set because no one modelled what a realistic ramp looks like for this specific role
• The founder and the new hire have different assumptions about how decisions will be made, because this was never made explicit
• Early underperformance triggers a loss of confidence before the leader has had a genuine chance to build foundations

None of these are inevitable. Most of them are avoidable with a brief that is specific, honest, and grounded in outcomes rather than activity.

What a better brief looks like

Getting the brief right doesn’t require more time – it requires a different focus. Instead of starting with the job description, start with the business problem. Instead of describing the ideal candidate, describe what the business looks like when this person is performing well. Instead of listing requirements, define the conditions for success and the environment the hire will be operating in.

And choose a search partner who will push back on the brief rather than simply execute it – one who brings genuine market intelligence to the conversation and who stays engaged beyond the hire itself.

In a market moving as fast as AI infrastructure, senior leadership decisions carry outsized risk and impact. The brief is where that risk either gets managed or ignored.
