Ask any hedge fund CPO what keeps them up at night.
Increasingly, it is not the market. It is whether one person leaving breaks the back office.

In brief
Talent Risk Is Now an Operational Risk
Why the non-investment functions of a hedge fund carry more risk than most operating models price in
TL;DR
- Talent risk has moved from a hiring inconvenience to a named operational risk. ACA Group's 2026 COO Priorities research ranks it third among the five issues reshaping investment operations this year.
- It rarely arrives as a crisis. It builds quietly — one person absorbs a gap in process or resourcing, the gap never gets rebuilt, and the fund becomes structurally dependent on that person staying.
- Recent hiring data backs this up: senior appointments across the market are concentrating in risk leadership, data and engineering, infrastructure and trading support — the non-investment functions, not just the desk.
- Three questions any COO can ask this week to find out where their own fund is exposed.
- The fix is not simply more headcount. It is designing non-investment functions so that no single person is the plan.
The risk
It doesn't arrive as a crisis
Ask any hedge fund COO what keeps them up at night, and increasingly the answer isn't the market. It's whether one person leaving breaks the back office.
That's a strange thing to sit alongside genuine tail risks — a liquidity event, a prime broker relationship under strain, a regulatory finding. But talent risk in a fund's non-investment functions has earned its place on that list, and the research now backs up what most experienced COOs already sense: it's under-discussed relative to how much damage it can do.
The research
What the research says
ACA Group's 2026 COO Priorities research, which surveys the issues reshaping investment operations this year, ranks talent risk third out of five — a notable position for something that, a few years ago, would have been filed under "HR" rather than "operational risk."
“Many organizations continue to rely on exceptional individuals who consistently bridge gaps in process design, automation, or resourcing. While these employees often become invaluable, reliance on a small number of individuals to compensate for process or resource gaps can create significant operational risk.”
Having spent this year embedded directly inside a multi-billion-dollar global macro hedge fund's HR function, I'd go further: third is generous. In a lean back office, the gap between "this person is excellent" and "this person is the control" narrows fast, and most funds don't notice the line has been crossed until the person hands in their notice.
The market's own hiring behaviour supports this reading. A recent review of senior hedge fund appointments by Resonanz Capital — drawing on over 40 publicly reported moves across more than 20 large hedge fund firms — found that recent hiring activity is concentrating specifically in "risk leadership, data and engineering, infrastructure, and trading support." In other words, the smart money isn't just staffing up the desk. It's reinforcing precisely the functions that talent risk exposes: the ones that keep a fund running when nobody's watching, and that rarely get credit until something breaks.
How it builds
How talent risk actually creeps in
Talent risk doesn't announce itself. It builds in three quiet stages, and none of them look like a problem at the time.
- 01
Someone plugs a gap.
A subscription deadline gets covered by the one person who always catches errors before they hit NAV. Nobody asked them to become the safety net — they just happened to be good enough, and available enough, to make the deadline work.
- 02
Because it worked, nobody rebuilds the control.
There's no incentive to invest in a fix for a problem that, on paper, isn't happening. The deadline gets hit every cycle. The process looks healthy on every dashboard that matters.
- 03
Complacency sets in.
The fund now depends on that person as a permanent safety net, and stays exposed for as long as they do. The risk hasn't gone away — it's simply been made invisible by someone's competence, which is precisely what makes it dangerous. A control that exists because one person is diligent is not a control. It's a single point of failure with a good track record, right up until the day it isn't there.
Ask this week
Three questions worth asking this week
If you run operations, compliance, technology or risk at a fund, three questions will tell you fairly quickly where your own exposure sits.
Could you still meet your regulatory filing deadlines if your Head of Compliance was unexpectedly out for six weeks?
This isn't a hypothetical about illness or attrition specifically — it's a stress test of whether your filing process depends on institutional knowledge that lives in one person's head, or on a process that would survive their absence.
If your ops lead was suddenly out, would settlements still go through — or does your backup only exist on the org chart?
A named deputy is not the same as a capable one. Plenty of succession plans are accurate on paper and untested in practice, which is a distinction you only discover at the worst possible moment.
Have you documented the judgement calls behind month-end close, or does that knowledge leave when the person does?
The mechanical steps of a process are usually written down somewhere. The judgement calls — what to flag, what to let through, what 'normal' actually looks like for this book — almost never are, and they're the part that actually matters when something looks slightly off.
None of these questions require a consultant or a six-month review to answer. Most COOs already know, intuitively, where the honest answer is uncomfortable. The value of asking them explicitly is that it turns a vague unease into something you can actually resource against.
The fix
The fix isn't more headcount
It's tempting to read all of this as a case for simply hiring more people, but that misses the point. A fund can be overstaffed in its non-investment functions and still carry acute key-person risk, if the structure still routes every hard decision through one individual.
The better frame is this: in hedge funds, the best back-office hire doesn't plug today's gap. They make the operating model less dependent on any one person. That's a different hiring brief than "we need someone to do X" — it's a brief about resilience, succession and institutional memory, and it changes who you should be looking for and how you assess them.
It also changes how you think about timing. Most funds only address key-person risk reactively, after someone resigns and the gap in the process becomes visible to everyone at once. By then, you're hiring under pressure, against a deadline, for a role whose real requirements you've never had to articulate because one person quietly handled them for years. The funds getting this right are doing the diagnostic work — the kind captured in the three questions above — before that moment arrives, not during it.
AJH Search & Advisory is an executive search practice focused exclusively on the non-investment functions of hedge funds and alternative investment managers — Legal, Compliance, Risk, Operations, HR, Commercial, Technology and Finance — across the UK, Europe and the Middle East.
If any of the questions above raised an honest "I'm not sure," that's usually the right place to start a conversation.
