The pattern: Consulting firms grow steadily to ~15 people, then stall. Not because the market dries up—because they hit an operational ceiling.
There's a pattern in consulting firms. They grow steadily to about 15 people, then stall. The founders can't hold everything in their heads anymore. But they haven't built systems that can hold it for them.
The 15-Person Threshold
AT 15 PEOPLE, YOU HAVE:┌─────────────────────────────────────────────────────┐ │ 8-10 active client engagements │ │ 20-30 active projects across those clients │ │ 10-15 pipeline opportunities │ │ Utilization to balance across the team │ │ ════════════════════════════════════════════════ │ │ COMPLEXITY > ONE PERSON'S MENTAL MODEL │ └─────────────────────────────────────────────────────┘
Below 15: A strong founding partner can manage through personal attention. They know every client, every project, every team member's capacity. Operations happen in their head.
Above 15: That mental model breaks. Details slip. Clients get less attention. Projects drift. The founders work harder and things still fall through cracks.
The Three Typical Responses
None of these break through the ceiling. They just cope with it.
What Actually Works
Breaking the ceiling requires less complexity to manage, not more people managing complexity.
| Instead of... | You need... |
|---|---|
| CRM + tracker + spreadsheet + calendar | Single source of truth |
| Reviewing everything for problems | Exception-based attention |
| Funneling through founders | Distributed awareness |
| Someone chasing updates | Automated coordination |
The 50-Person Firm That Runs Like 15
With the right operational model, a 50-person firm can feel as manageable as a 15-person firm. The founders still have clarity on every client relationship. They still know which projects need attention.
They just don't have to manually maintain that awareness. It's surfaced for them.
This is the difference between operations as overhead and operations as infrastructure:
Operations overhead: Scales linearly with size
────────────────────────▶
Operations infrastructure: Scales logarithmically

If you're approaching the 15-person ceiling, the question isn't whether to invest in operations. It's what kind of investment: more people managing more spreadsheets (linear scaling), or systems that handle coordination automatically (logarithmic scaling).
