When a B2B company hits a growth ceiling, the instinct is often to bring in consultants. But the type of consultant matters enormously. Hiring a management consultant for a revenue problem — or a GTM consultant for an organisational design challenge — wastes time and money.
What Is a GTM Consultant?
A go-to-market (GTM) consultant specialises in the commercial engine of a business: how it generates demand, converts pipeline, retains customers, and scales revenue. They typically have direct experience leading sales, marketing, or revenue operations teams. Their work is hands-on, execution-oriented, and measured in commercial outcomes — pipeline generated, conversion rates improved, revenue grown.
GTM consultants often work as fractional leaders (fractional CRO, VP Sales, Head of Marketing) or as strategic advisors who diagnose and fix specific commercial problems. Their engagements tend to be shorter and more focused than traditional management consulting.
What Is a Management Consultant?
Management consultants work across the full breadth of organisational strategy and operations. They advise on market entry, organisational restructuring, cost optimisation, digital transformation, and M&A integration. The large firms (McKinsey, BCG, Bain, Deloitte) deploy teams of analysts and associates, producing comprehensive strategy decks and transformation roadmaps.

When to Hire a GTM Consultant
- Your pipeline has stalled and you're not sure why
- Sales and marketing teams are misaligned on ICP, messaging, or handoffs
- You're entering a new market segment and need a commercial strategy
- Your CRM and revenue operations are a mess
- You need a fractional CRO or VP Sales while you hire full-time
- Post-acquisition, you need to integrate or restructure the commercial function
When to Hire a Management Consultant
- You need a full organisational restructure beyond the commercial function
- You're evaluating M&A targets and need due diligence
- The board requires an independent strategic review
- You need to reduce costs across the entire business
- You're planning a digital transformation that spans every department
The Bottom Line
If your problem is "we're not growing fast enough" and the root cause is in how you sell, market, or operate commercially — you need a GTM consultant. If your problem is broader than the commercial function, a management consultant may be more appropriate. Many companies benefit from both at different stages.
