Growth Strategy Firms: What They Do That Internal Teams Can’t

Growth strategy firms are specialist consultancies that help businesses identify where revenue growth will come from, build the commercial logic to pursue it, and design the go-to-market approach to make it happen. They sit somewhere between management consultants and marketing agencies, combining market analysis, competitive positioning, and commercial planning into a coherent growth thesis.

The distinction that matters is this: a growth strategy firm is not there to run your campaigns. They are there to tell you which bets are worth making before you spend anything.

What Does a Growth Strategy Firm Actually Do?

The category is broader than it sounds. Some firms operate at pure corporate strategy level, advising on market entry, M&A, and portfolio decisions. Others work closer to the commercial and marketing layer, helping businesses figure out how to grow revenue within their existing category or adjacent to it. A few do both.

At the practical level, most engagements involve some version of the following: diagnosing where growth has stalled or slowed, identifying the highest-probability sources of new revenue, assessing the competitive landscape with enough rigour to inform positioning, and producing a prioritised plan that the client’s team can actually execute.

The better firms also pressure-test assumptions. One of the most common problems I saw running agencies was clients who had convinced themselves their next wave of growth would come from an audience segment that, on examination, had no real intent to buy. The strategy looked logical on a whiteboard. It fell apart when you looked at actual market behaviour. A good growth strategy firm catches that before it becomes an expensive mistake.

If you want a broader view of how growth strategy connects to go-to-market planning, channel selection, and commercial execution, the Go-To-Market and Growth Strategy hub covers the full landscape.

Why Internal Teams Struggle to Do This Work Themselves

It is not a capability problem in most cases. Internal teams often have sharp strategists, good data, and genuine market knowledge. The problem is proximity.

When you are inside a business, you are surrounded by its existing customers, its existing product logic, and its existing assumptions about what the market wants. That shapes how you see growth opportunities. You tend to look for more of what is already working rather than questioning whether what is working is actually the ceiling.

I spent a chunk of my earlier career overvaluing lower-funnel performance signals because they were the clearest and most measurable. The numbers looked good. But I came to understand that much of what performance marketing gets credited for was going to happen anyway. The customer was already in market. We captured intent we did not create. That is not growth strategy. That is demand harvesting. And confusing the two is one of the most expensive mistakes a marketing function can make.

Growth requires reaching people who are not already looking for you. That is a fundamentally different problem, and it requires a different lens. External firms bring that lens without the internal politics that tend to filter out uncomfortable conclusions.

Vidyard’s analysis of why go-to-market execution feels harder than it used to points to something real here: the buying environment has changed, and strategies built on capturing existing demand are running into diminishing returns. The firms that help clients build genuine reach into new audiences are earning their fees. The ones repackaging attribution dashboards are not.

How to Tell the Difference Between a Real Growth Firm and a Rebranded Consultancy

This is where the category gets murky. The term “growth strategy” has been applied to enough different things that it has lost some of its precision. Management consultancies use it. Digital agencies use it. Solo practitioners with a Notion template use it. The label tells you almost nothing.

What distinguishes a firm worth engaging from one that will produce a polished deck and leave you no clearer than before comes down to a few things.

First, they should be able to tell you, specifically, where they think your growth will come from before they have done any work. Not a precise answer, but a hypothesis. If a firm cannot form a working hypothesis from a 30-minute briefing, they are not thinking commercially. They are waiting to fill a framework.

Second, they should push back on your assumptions. The best engagement I ever had with an external strategist started with them telling me, politely but directly, that the market segment we were prioritising was too small to deliver the revenue target we had set. That conversation was uncomfortable. It was also correct. The firms that just validate your existing thinking are not adding value. They are adding comfort.

Third, they should have a point of view on execution, not just diagnosis. A growth thesis that stops at “target this segment with this message” is half a strategy. The firms that understand how channel selection, pricing, and go-to-market sequencing affect whether the strategy actually lands are worth considerably more than those who hand off a slide deck and disappear.

BCG’s work on go-to-market strategy in B2B markets makes a similar point about the commercial specificity required to make growth strategy actionable, particularly around pricing architecture and how it signals positioning in competitive markets.

The Frameworks Growth Strategy Firms Use (and Which Ones Actually Matter)

Most growth strategy work draws on a relatively small set of analytical frameworks. Ansoff’s matrix, the market penetration versus market development distinction, jobs-to-be-done analysis, competitive positioning maps. These are not secrets. You can read about all of them in an afternoon.

The frameworks are not the value. The value is in how rigorously they are applied to your specific commercial situation, and whether the firm has the intellectual honesty to tell you when the framework does not fit.

Market penetration, for example, is often the right starting point for a business that has genuine headroom in its existing category. Semrush’s breakdown of market penetration strategy is a solid primer on the mechanics. But penetration strategy assumes the category is large enough and that your competitive position is strong enough to take share. If neither of those conditions holds, you need a different conversation entirely.

The Forrester intelligent growth model takes a different angle, focusing on how businesses sequence growth investments across existing and new customer bases over time. Their framing of intelligent growth is useful precisely because it resists the temptation to treat all growth opportunities as equivalent. Some bets compound. Others just cost money.

What I have found, after watching a lot of strategy engagements from both sides of the table, is that the firms who use frameworks as a starting point for thinking tend to produce better work than those who use them as a substitute for it. The framework gets you to the right questions. It does not answer them.

Where Growth Hacking Fits (and Where It Does Not)

The growth hacking conversation is worth having briefly, because some firms position themselves in this space and it means something quite different from growth strategy.

Growth hacking, in its original formulation, was about finding rapid, often unconventional ways to acquire users at scale with limited resources. It emerged from the early startup world and produced some genuinely interesting case studies. Semrush’s examples of growth hacking in practice covers the canonical ones. Dropbox’s referral loop. Airbnb’s Craigslist integration. These are real and instructive.

But growth hacking is a set of tactics. It is not a strategy. And for most established businesses, the question is not “how do we acquire users cheaply” but “which markets should we be in, with which offer, at what price, through which channels.” That is a strategic question, and it requires strategic thinking, not a growth experiment backlog.

Crazy Egg’s overview of growth hacking is honest about this distinction. The tactics work best when the strategic foundations are already solid. If you do not know who you are growing for and why they should choose you, running referral experiments is just noise.

I have seen businesses spend six months on growth experiments while the actual problem was a positioning issue that no amount of tactical cleverness was going to fix. The growth strategy conversation has to happen before the tactics conversation. That is not a sequencing preference. It is a commercial necessity.

What a Good Engagement With a Growth Strategy Firm Looks Like

The engagements that produce real commercial value tend to share a few characteristics.

They start with a clear commercial problem, not a brief for a deliverable. “We need a growth strategy” is not a brief. “We have grown 15 percent year on year for three years and we are now flat, and we do not know whether that is a market problem, a positioning problem, or a go-to-market problem” is a brief. The specificity of the problem shapes the quality of the answer.

They involve the right people on the client side. Growth strategy work that is commissioned by marketing and never reaches the commercial or product leadership tends to produce recommendations that cannot be acted on. The best engagements I have seen have had genuine executive sponsorship, with someone senior enough to make decisions in the room.

They produce a prioritised output, not an exhaustive one. The temptation for strategy firms is to demonstrate the depth of their analysis by presenting every option they considered. The temptation for clients is to ask for comprehensiveness because it feels like value. Neither produces a usable output. What you want is a clear-eyed view of the two or three highest-probability growth moves, with the commercial logic behind each and a realistic assessment of what execution requires.

Early in my career, I was handed a whiteboard pen in the middle of a client brainstorm when the agency founder had to leave the room. The instinct was to fill the whiteboard with everything I knew. What actually worked was asking one sharp question that reframed the problem. That is what good strategy looks like in practice. Not more surface area. A better question.

When You Do Not Need a Growth Strategy Firm

This is worth saying plainly. Not every business needs an external growth strategy firm, and commissioning one when you do not is an expensive way to produce a document that confirms what you already knew.

If your growth has stalled because of execution problems rather than strategic ones, a strategy firm will not fix it. If you already have a clear view of where your growth will come from and the constraint is capability or resource, you need different help. If your market is moving fast enough that a three-month strategy engagement will be outdated before it is finished, the better investment is in faster internal decision-making, not external analysis.

The businesses that get genuine value from growth strategy firms tend to be at an inflection point: post-product-market fit but pre-scale, entering a new market, facing a competitive threat that their existing playbook cannot address, or trying to move from one growth phase to the next. At those moments, the outside perspective and the commercial rigour that a good firm brings is worth considerably more than the fee.

Vidyard’s Future Revenue Report surfaces something relevant here: the gap between pipeline potential and actual revenue capture is often a go-to-market design problem, not a demand problem. That is exactly the kind of diagnosis a growth strategy firm should be equipped to make.
