In finance, risk rarely comes when you expect it. It hides in concentration, in single points of failure, in dependencies that seem to work well until the day they don’t. Most financial leaders have learned to recognize it in portfolios, parties, and liquidity. Very few use the same discipline in their careers, where one of the most common and least explored risks lies in the open: the founder or principal becoming too important to the day-to-day running of the business.
For founder-led financial firms, retail advisors, fund managers, fintech operators, and professional services businesses, key person dependency is not a management concern. Exposure to measurable performance with consequences for continuity, measurement, and consistency. And the way it is often handled, or not handled, reveals a blind spot that the most critical structures cannot tolerate elsewhere.
Dependence that looks like surrender
The pattern is familiar. An entrepreneur builds a business through personal effort and deep involvement in every activity. As the company grows, that involvement is limited. It expands. The principal becomes the point of authorization, the owner of the relationship, the person in charge of the emergency and the process alike because they always have it.
From the inside, this reads like a commitment. From a risk perspective, it reads like focus. When a single person holds operational knowledge, client relationships, and decision authority that is not available anywhere else in the business, the company has created multiple exposures to that single person’s availability, power, and continued existence.
Investors and investors understand this well. Key person risk is a common line item with due diligence, and businesses that can’t demonstrate operational continuity beyond the founder are often downgraded or outsourced. A firm’s exit value if one person leaves is less expensive than one with distribution power, regardless of current performance.
Chance costs no one in literature
Before the question of proceeding arises, there are simple and quick costs, and they appear every single working day. It is the value that is lost when the most valuable person in the company spends his time on work that does not need him.
The numbers are well written. A study conducted by Harvard Business School professors Michael Porter and Nitin Nohria, which tracked the work patterns of senior executives over 60,000 hours, found that senior leaders spend more of their time interacting, communicating, and managing work instead of the only strategic work they can do. Email and general communication alone consumed about a quarter of their working hours.
Translate that into financial goals. A principal whose time is worth £150,000 a year effectively values each hour of work at around £70 to £80. When 40 to 60 percent of that time goes to planning, inbox management, document management, and administrative communication, the company is using its most expensive resource against work that a skilled assistant can do for a fraction of the cost. The cost of said opportunities runs into tens of thousands of pounds a year, with widely cited analysis putting the value at around £84,000 for a leader at that salary level.
That is not a soft cost. It’s real economic value, or it’s lost entirely because the high-value work isn’t done, or it’s brought in by someone with many times the hourly rate than the work warrants. In any other context, a financial leader would immediately recognize this as a misallocation of funds. Used in their own time, it is often not examined.
The decision not to include appropriate support, in other words, is not saving. It’s an ongoing expense that accrues quarterly, only invisible because it doesn’t appear on the invoice.
The employment response, and why it has stopped
A common response is hiring, building a support layer that absorbs the load and creates redundancy. The logic makes sense. Execution, for many founder-led financial firms, is where it goes wrong.
The cost of senior support talent in the UK has risen sharply. In London, the average salary for an executive assistant is now more than 46,000 pounds a year, according to Glassdoor data, with experienced assistants supporting C-suite principals in financial services earning 60,000 pounds or more before bonus. When employer’s national insurance, which rises to 15 per cent by April 2025, pension contributions, utilities, and rent are added, the fully loaded cost of employing one adult typically exceeds £70,000 a year.
When compared to opportunity costs, however, the comparison redefines itself. A fully loaded rental of £70,000 that re-claims even half of the principal’s misallocated time pays for itself several times over. The skepticism behind hiring focuses on the tangible costs of payroll while ignoring the huge intangible costs it will eliminate.
There is also the matter of time. Hiring a senior assistant in the current London market is not fast. Professional recruiters report an average time to hire of about eight weeks for senior roles, and three out of four report difficulty finding suitable candidates for C-suite placements. The gap between recognizing a problem and solving it can stretch throughout the quarter, when opportunity costs continue to grow.
Manage support as a way to manage risk, not overhead
The restructuring that more finance leaders are beginning to use is to treat management support not as an option but as an ongoing control, the same level as a disaster recovery plan, support center, or succession structure. When viewed that way, the question changes. It is no longer whether the company can afford the support. Whether it can afford unregulated dependence and the associated opportunity costs.
This change has coincided with the maturation of alternatives to traditional traditional hiring. Subscription-based assistant models, where a dedicated and vetted assistant is offered as an ongoing service rather than an employee, have gone from marginal to mainstream over the past three years. For financial firms, the appeal is partly cost, with dedicated support available partly full-value in-house, and partly on-premise.
The specialty agency model often builds a resume that a single hire cannot provide. When a moving housekeeper creates an immediate gap, structured service includes handover procedures, backups, and facility continuity that survives any individual departure. For a financial leader who thinks in terms of risk, that difference is the whole point.
Firms exploring this route are increasingly turning to experts the UK’s largest recruitment agency that understands the discretion, privacy, and judgment required in the context of financial services, rather than the general arena. The distinction between assessment and response is important where sensitive information and high-level relationships are involved.
What good looks like
Financial firms that manage this well tend to share several characteristics. Identify, clearly, what information and relationships currently reside with one person and not elsewhere. Build at least one support layer that filters, documents, and handles the workload, reducing the principal’s involvement in work that does not require their specific authority. And they did this deliberately, as a risk decision and a capital with a defined reason, rather than waiting until burnout or a miss forced the issue.
How this is achieved, full employment, an agency model, or some combination, is more important than the recognition that it needs to be achieved at all. The goal is that financial leaders work everywhere except, often, for themselves: don’t let a critical skill concentrate in one area of failure, and don’t use your most expensive resource against your cheapest function.
The cost of getting it wrong
The downside of uncontrolled key-person dependencies is rarely seen until it happens, and then it’s expensive. A principal stepping down unexpectedly, due to illness, travel, or simple exhaustion, leaves the business busy to rebuild knowledge and relationships that were never written down or shared. The continuity gap becomes the performance gap, and in the sales or fundraising process, it becomes the measurement gap.
Long before that, silent costs are already being paid, day after day, in the amount of overtime spent on work that you didn’t need. Directing finance leaders bring in all other risk categories, identify exposures, assess impact, build controls, it works cleanly here. Firms that recognize their performance as a legitimate aspect of that discipline are those that build businesses that have value beyond the ability of the founder to hold them together.
In an industry that prides itself on understanding risk and pricing it accurately, dependence on a single critical individual, and the steady leakage of value that goes with it, remains one of the most common and overlooked balance sheet exposures. It is also one of the most adjustable.
