Sector expertise: the case against generalists

By the partners · Point of view · 11 min read

Generalist advisers describe sector expertise as a nice-to-have. Operators know better. The difference between advice that lands and advice that floats is rarely analytical method — most competent firms can build a market model — it is whether the person presenting it has lived inside the industry's texture: its sales cycles, its margin quirks, its regulatory moods, its habitual self-deceptions.

This is not an argument for narrowness. It is an argument for honesty about where pattern recognition comes from, and a warning about where its absence shows up on the invoice.

What sector expertise actually buys

First, speed. A generalist spends the first third of any mandate learning how the industry makes money — who holds pricing power, where working capital hides, what the trade associations argue about. A sector-fluent adviser starts there. On a ten-week mandate, that is three weeks of fees recovered before any advice is offered.

Second, calibration. Every industry has a normal that would alarm an outsider: twelve-month sales cycles that are healthy, gross margins that look luxurious until distribution eats them, customer concentration that everyone has agreed not to mention. Sector fluency is knowing which anomalies are load-bearing. We watched a generalist firm flag a software company's 118% net revenue retention as "an outlier requiring explanation" — it is, of course, the single healthiest number in the sector, and the report lost the room for a week.

Third, and most valuable: access to the reference class. "Comparable companies" is a generalist's spreadsheet; sector experience is a decade of watching which of those comparables actually succeeded and why. When we advise a UK industrial group on DACH entry, the counsel that matters is not the market sizing — it is which three distributor archetypes failed there and the specific contract clause that would have saved them.

The generalist's defence, taken seriously

Generalists make two fair points. The first is that industry insiders can be captured by industry assumptions — nobody in a failing industry believes the failure is structural. This is real, and it is why sector expertise and independence must come from different places. Our panel is sector-fluent but deliberately not sector-monopolised: the advisor who knows industrial distribution cold has spent the last five years advising across its edges, watching it from boards in adjacent sectors, which is where structural change is visible first.

The second point is that method transfers. It does — partially. Frameworks for pricing, market entry and governance are genuinely portable. But method is the cheaper half of the product. The expensive half is judgement about which method this situation deserves, and judgement is fed by pattern recognition that only exposure builds.

How to test a firm's sector claim

Ask for the last five mandates in the sector, with outcomes and dates. Ask who staffed them — the partner whose bio says "technology" may have been selling services to technology companies, which is different from having run one. Ask what the firm believes the sector gets wrong; a fluent adviser answers with a specific, slightly uncomfortable observation, and a generalist answers with a trend report. Ask what changed in the sector's economics since 2022, and listen for whether the answer involves interest rates, labour or energy in the specific proportion your industry actually experiences them.

The best question is about failure: "tell us about a mandate in our sector that went badly, and what it taught you." Firms with genuine depth have these stories and tell them well. Firms without depth have no stories, which is itself the answer.

The cost of the learning curve

Boards should understand what happens, commercially, when a firm without sector depth takes the work anyway. Someone pays for the education. Usually it is split three ways: the client pays through the senior hours spent getting up to speed; the mandate pays through the calendar, because discovery stretches from two weeks to five; and the advice pays, invisibly, through caution — a firm unsure of the terrain hedges its recommendations, and hedged advice is expensive to read and harder to act on.

There is a version of this that is honest and fine. When we take an adjacent-sector mandate for a long-standing client, the engagement letter says "this is outside our core lines, here is how we will staff the learning, and here is the discount that acknowledges it." What is not fine is the same learning curve priced as expertise. The tell is in the early questions: a fluent adviser asks about the things the client did not think to mention; a learning adviser asks the client to explain the industry. The first is worth a fee. The second is a discovery phase, and should be priced as one.

Sector maps change

Depth has a shelf life, and the expiry is faster than reputations suggest. Industrial distribution's economics re-formed around post-pandemic inventory cycles in eighteen months. B2B software's pricing norms — seats, then usage, then outcomes — turned over three times in a decade. An adviser whose sector knowledge dates from their operating career is an adviser reading from a decade-old map, and the most dangerous kind of stale expertise is the kind that still sounds authoritative.

We manage this the way operators manage plant: current exposure or it does not count. Each panel member's sector claim is refreshed by live mandates or sitting boards within the last three years — not by a career-history paragraph. Where a sector has moved past our current exposure, we say the line has lapsed and either re-establish it or refer. Clients find this unnervingly blunt for about a week, after which it becomes the reason they stopped taking sector claims on faith anywhere else.

Our own sector lines

We hold deep lines in four sectors: industrials and advanced manufacturing, B2B software, financial services infrastructure, and consumer brands with retail exposure. Two more — energy transition services and healthcare services — we take selectively where governance or market-entry questions dominate. Outside these we decline or refer, because the honest alternative to sector expertise is not enthusiasm; it is a partner firm that has it.

When we take work outside our lines — occasionally, for a long-standing client whose situation we understand — we say so in the engagement letter, staff the learning curve explicitly, and price it as what it is. What we never do is borrow a sector credential from an adjacent logo on the website.

The mid-market complication

Mid-market companies face a sector dilemma that larger ones do not: the advisers with genuine depth in their niche often serve larger clients at larger fees, while the firms at mid-market price points are generalists. Our panel model exists to resolve exactly this. Senior operators with line experience in the sector, deployed at mid-market scope and price, without the leverage pyramid that makes big-firm economics infeasible below £250m revenue.

It is not a perfect resolution — the bench is smaller, the diaries are tighter, and we decline more work than a generalist can afford to. But the alternative is advice from people learning your industry at your expense, and most boards who have paid that invoice once do not pay it twice.
