But they're cheaper on a per-outcome basis because they start faster, bring pre-built playbooks, and don't require you to build a sales organization around them. ```mermaid flowchart TD A[Founder realizes concentration risk] --> B{ARR over 2M?} B -->|No| C[Focus on founder-led sales / product-market fit] B -->|Yes| D{Can afford a retainer?} D -->|No| E[Hire a sales consultant or part-time VP of Sales] D -->|Yes| F[Engage fractional CRO for 3-month trial] F --> G[Audit pipeline and customer concentration] G --> H[Define adjacent segment and 6-month target] H --> I[Build and execute diversification plan] I --> J{Concentration below 30%?} J -->|No| K[Extend fractional engagement or consider full-time CRO] J -->|Yes| L[Transition to fractional CRO on retainer or hire full-time]

Should I Hire a Fractional CRO If I Am Too Dependent on One Big Customer — figure 1

If your product only solves a problem for one type of customer (e.g., a custom integration for a specific industry), no amount of sales strategy will create diversification. In this case, invest in product expansion first - hire a fractional product manager or CTO to build features for adjacent markets. A fractional CRO can only sell what exists. 2. Your big customer is also your primary investor or board member If your largest customer has board representation or significant equity, their interests may conflict with diversification. A fractional CRO may face resistance when trying to shift focus away from that account. In this case, consider a fractional CEO or strategic advisor who can navigate the power dynamics before tackling sales. 3. Your revenue is below 1M ARR Below 1M ARR, your biggest problem is typically product-market fit, not customer concentration. A fractional CRO at a retainer would consume a dangerous percentage of your revenue. Instead, hire a part-time sales consultant (a retainer) or focus on founder-led sales with a clear goal of reaching 2M ARR before bringing in fractional executive help. In these scenarios, the money is better spent on product development, customer research, or a fractional COO to fix operational bottlenecks. A fractional CRO can only be effective when the foundation - product, market fit, and basic sales process - is already in place. ## Related questions - What percentage of customer concentration is too high for a B2B SaaS company?
