There is a moment in business development that most partners recognise immediately, even if they have never quite named it.

The meeting is going well. The relationship is warm. The work being discussed is exactly the kind of work the firm is built to do. And then the question arrives — sometimes bluntly, sometimes wrapped in courtesy, but always with the same weight behind it.

“Why you? Why your firm?”

The partner knows it is coming. They know it matters. And they know, in the moment it lands, that their answer is not quite what it should be.

This is not a question that catches people unprepared because they haven’t thought about it. Most senior partners in professional services have given it a great deal of thought. They can produce, at short notice, a detailed and accurate account of their firm’s capabilities — its depth of expertise, its track record, its sector knowledge, its client relationships, its geographic reach.

Ask them to complete a directory submission, and they will do so with confidence and precision, marshalling evidence across multiple categories with the fluency of people who know their firm well.

The difficulty is not the evidence. It is the claim the evidence is meant to support.

Ask ten partners why us, and you’ll probably get twelve different answers.

A senior partner at a major firm said this to me recently, with the particular weariness of someone who has been on both sides of the problem — both the partner struggling to answer and the leader trying to resolve it. She wasn’t describing a firm in trouble. She was describing something far more common: a firm that is genuinely strong, that knows it is genuinely strong, and that has never quite settled on the single, overarching account of what that strength adds up to.

The bullet points exist. The umbrella is missing.

An unfinished conversation

What the pitch room exposes is not a failure of preparation or a weakness of leadership. It is the visibility of a conversation that most partnerships are still, at some level, having.

The question of what a firm is truly trying to be — what it is built to win, what it will compete on, what it is prepared to say no to in order to say yes more decisively elsewhere — is rarely resolved in a single strategy meeting. It surfaces and retreats. It gets close to resolution, and then a merger shifts the partnership’s composition, a new practice area opens, or a leadership transition changes the room. The conversation continues, just below the threshold of urgency, until something makes it visible again.

The pitch room is one of those moments. So is a lateral hire who, in their first week, asks what makes this firm different from the three others that approached them. So is a marketing leader trying to brief an agency on what the firm stands for, only to realise there is no single answer to give.

The difficulty is not the evidence. It is the claim the evidence is meant to support.

It is tempting to assume this is primarily a large-firm problem — that complexity and scale are what make the question hard to answer. There is something to that. The more diverse the practice mix, the more geographies in play, the more distinct the leadership tribes, the harder it is to land on a proposition that is genuinely shared rather than merely agreed to in the room.

But size alone is not the determining factor. Look at the firms that have built some of the most commanding positions in their respective markets. In advisory, firms like McKinsey and PA Consulting. In law, Kirkland and Quinn Emanuel. In finance, Goldman Sachs and Jane Street. In infrastructure and property, Arup and Montagu Evans.

All of them operate in crowded, competitive markets. All of them are large, complex, or both. And all of them have answers to the “why us” question that are clear enough to guide decisions, sharp enough to travel, and robust enough to hold under scrutiny.

There are also relatively small firms that struggle because, despite their size, their practice mix is so diverse that no obvious common thread presents itself.

The real variable is not scale. It is strategic resolve — the willingness of leadership to achieve genuine agreement on what the firm is trying to be, and to hold that line when the pressure to be all things to all clients is considerable.

None of this reflects badly on the firm or its people. Partnerships are federations of high-performing individuals, and the tension between individual excellence and collective identity is structural, not accidental. Asking partners who have built their reputations through their own work and their own relationships to subordinate that to a single shared proposition is not a small thing. It requires genuine agreement — not polite acquiescence — that takes time and the right kind of conversation to reach.

The cost of not reaching it is rarely dramatic. It shows up as inconsistency rather than crisis. Pitches that vary more than they should between partners. Introductions that describe the firm differently depending on who makes them. A marketing function that produces considerable output but finds it difficult to land a message that cuts through, because the message keeps shifting depending on who reviews it. And, in the pitch room, a moment of hesitation where there should be clarity.

What resolution makes possible

When a firm does reach genuine agreement on its answer to the “why us” question — when that answer is specific enough to discriminate, credible enough to survive scrutiny, and simple enough to be used consistently by partners who are not natural marketeers — the effect is not only external. It is also internal.

Partners speak with greater confidence in business development conversations, not because they have been given a script, but because they are drawing on something they actually believe. Cross-selling becomes more natural because different practices are operating from the same underlying logic. New partners and senior hires integrate more quickly because there is a shared account of what the firm is and what it is trying to do.

Marketing becomes a strategic lever rather than a production function, because there is finally something sharp enough to amplify.

In the work I do with firms across these sectors, and in looking at the most successful practices in professional services more broadly, the pattern is consistent. A clear sense of identity correlates strongly with commercial momentum — not just in client development, but in recruitment, in strategic decision-making, and in the ability to hold a partnership together around a shared direction.

These things are connected. A firm that knows what it stands for attracts people who want to be part of that, wins work that reinforces it, and builds a reputation that compounds over time.

The final step — arriving at a single, clear, overarching concept that crystallises what the firm is and why it is the right choice — is where the real leverage lies. Most firms can articulate their strengths. Many can describe their strategy. Far fewer can express both in a form that is immediately compelling to a sophisticated buyer who has choices, constraints, and colleagues to persuade.

That last step is not merely additive. In a crowded market where technical excellence is assumed and differentiation is genuinely difficult, a firm that has completed it enjoys an advantage that is exponentially greater than the distance between it and those that have not. Indeed, our analysis, based on the unusually transparent commercial data published by the Big Law sector, shows that firms that achieve this distinction are 2-3x more profitable than their otherwise near-identical peers.

This can appear counterintuitive to those not steeped in how brands work in competitive markets. But take a look outside of professional services at brands like Apple, Mercedes, and Hermes, and it’s much easier to see how this apparently small difference makes all the difference.

There is a further dimension that is easy to overlook. In most business development situations, a partner is selling one service — one practice area, one team, one solution to a specific problem. But they are doing so under a single firm name. That name carries an identity, whether the firm has shaped it deliberately or not. The partner selling restructuring advice and the partner selling employment law are, in the eyes of the client, representatives of the same brand.

When the overarching firm proposition is clear, each practice area borrows strength from it. When it is absent, each practice is left to make its case in isolation — and the firm’s most powerful asset, its collective reputation, goes to work for nobody in particular.

This is why developing a clear, crystalline statement of overall firm value is not merely a marketing exercise. As I explored in a recent piece on why strategy needs a big idea, firms that give their strategic development a clear thematic identity — one that is compelling internally as well as externally — find that it pays dividends well beyond the pitch room. It guides decisions. It focuses investment. It gives leadership a reference point that holds under pressure.

The pitch room doesn’t reveal weakness. It reveals that the conversation hasn’t yet reached a conclusion.

The “why us” question is, in the end, a gift — even when it is uncomfortable. It makes visible something that most successful firms need to resolve and rarely find the occasion to prioritise. The partner who hesitates in that moment is not failing their firm. They are carrying, on their own, the weight of an answer that the firm as a whole has not yet agreed to give.

The question is whether it takes another lost pitch to create the urgency, or whether the conversation gets finished before that
