Your Next Sales Hire Has a 50% Chance of Failing. Here’s How to Beat the Odds

About half of sales leaders fail in their first 18–24 months. That’s according to Harvard Business Review. If you’re a founder hiring someone to sell your expertise, those aren’t great odds.

The cost of getting it wrong goes beyond money. It’s time, energy, culture, and credibility. You trusted someone to represent your firm. They didn’t deliver. Now you’re cleaning up the mess and starting over.

You can beat those odds. It starts with a clear, repeatable process. Here are four ways to increase your sales hiring hit rate.

Check Your Assumptions

Before you write a job description, slow down. Review your past hires. What worked? What didn’t? Be honest about what your business actually needs right now — not what you wish it needed.

Many founders carry assumptions about who will succeed in their firm. Some of those assumptions come from past wins. Others come from gut feelings. Neither is reliable on its own. Write down what success looks like in this role. Focus on outcomes. What will this person accomplish in 6, 12, and 18 months? Start there and work backward.

Document your full hiring process and timeline. This keeps things moving. It sets expectations for candidates and your team. It also makes sure none of these steps get skipped.

Get Specific About the Role and the Person

Define the role first. What does the day-to-day look like? What metrics will they own? Who will they work with internally and externally? This sounds basic. But most job descriptions blur the role with the ideal candidate. Separate them.

Then build a job profile that goes beyond the job description. What skills, traits, and experience does this person need? What can you train versus what they need to bring? Curiosity and persistence are hard to teach. Your industry and firm knowledge are not. Weigh your criteria accordingly.

Trust but Validate

Salespeople are good at selling themselves. That’s literally the job. So, dig deeper than what feels comfortable.

One of my favorite interview questions is simple: “Tell me about the sale you are most proud of.” This tells me how someone views sales. But I don’t stop there. I ask: What was the situation? Who was involved? What was the outcome? What did you learn? What would you do differently?

This question once helped a client avoid a costly mistake. The candidate described a major deal with confidence. But as we dug in, it became clear they played a small role in a team effort. They had very little to do with closing the deal. Miss hire averted.

Go beyond behavioral questions. Test their ability. The sports world has figured this out. Athletes prove their skills before they make the team. Do the same. Give candidates a real scenario to prepare for in advance. Something based on what they’ll do in the role.

You’ll learn a lot. How they prepare. How they perform. How they respond to feedback. Debrief the exercise with them. You’ll see what they’re made of. Assessments can also reveal sales skills, traits, and motivations that interviews alone won’t surface.

Set Them Up to Succeed

Be upfront about what the job is and isn’t. No firm is perfect. Tell candidates what isn’t perfect about yours. Let them join with their eyes wide open.

We’ve actually talked people out of working with us using this approach. Better to know beforehand than to find out three months in.

Then invest in onboarding. Don’t assume they’ll “figure it out.” They might know how to sell. But do they know how you want it done? Create an onboarding plan with clear milestones and validation. Have them practice presentations with you, not in front of your clients. Be intentional about who trains them and what they learn. Don’t just have them shadow others. You may be replicating habits you don’t want.

The Bottom Line

This isn’t a silver bullet. You’ll still get it wrong sometimes. But a clear process will help you get it right more often. And when you do, your team, your clients, and your firm will feel the difference.
