How Firms Hit $50m: Breaking Through Consulting Firm Growth Walls

Insight 1: The First Wall Is Founder Bandwidth

In the early years, the founder being everywhere works. Then it becomes the bottleneck. The business outgrows one person’s time and decision-making capacity, even if that person is doing everything “right”. The move is shifting from founder-led execution to leaders who truly own functions and outcomes.

Insight 2: The Next Wall Is Decision Centralization

This one is sneaky.

You hire smart people. You add leadership. But everyone still routes decisions through the top. Slides get checked. Proposals get reviewed. Client conversations get escalated. The founder is still the centre, just with a larger orbit.

Mark’s lesson here is blunt: breaking through requires decentralizing decision-making so leaders can run parts of the company without daily involvement.

Insight 3: Scale Comes From Leaders Who Can Run a Chunk Of The Business

Mark describes a mental model that many consulting firms will recognise: if one leader can run a meaningful chunk of the business end-to-end, you can replicate that capability and expand capacity without everything funnelling back to the founder.

Dominique’s angle here is important: this is also where roles change. Being a great individual contributor is no longer enough. At scale, leaders must recruit, coach, and replicate performance through a team.

Insight 4: Focus Feels Risky, But It Makes Growth Easier

Another common growth stall is being “a firm that does everything”.

Mark shares how during his time as CEO of Nexient, they shifted from broadly doing anything related to software to a sharper point of view: custom software with great user experience. That clarity made sales easier, delivery cleaner, and the brand more memorable.

They even tested a bold message early: “Life’s too short for crappy software.” It worked because it was specific, human, and easy to repeat.

Dominique calls out the real fear behind focus: you have to say no to revenue. That feels risky when you are hungry to grow. But without focus, you end up with a patchwork firm that is hard to scale.

Insight 5: Incentives Need To Reward Healthy Growth, Not Just Activity

As firms scale, misaligned incentives quietly create margin problems. Mark talks through structuring senior commercial roles so performance ties to both growth and profitability, not just bringing in work at any cost. The point is straightforward: if you want disciplined scale, pay for disciplined outcomes.

Dominique adds that incentives are not just a sales thing. Delivery leadership needs clear commercial outcomes too, otherwise the business grows in revenue while profitability quietly erodes.

If you are feeling a growth wall right now, the value of this conversation is how practical it is. It helps you identify the constraint that is actually slowing you down, whether it is founder bandwidth, centralised decisions, unclear positioning, or incentives that reward the wrong behaviour.
