The 3 Biggest Mistakes B2B Startups Make When Building a Sales Team

Lessons from the field—and why getting this right is mission-critical to scale

I’ve had the chance to build sales teams from scratch—sometimes without playbooks, funding, or even a margin for error. From expanding into 50+ markets at Alotech/Call Center Studio to now working hands-on with SaaS founders at scaleWW and Katalis Alliance, I’ve seen one thing remain consistent:

Sales either unlocks momentum—or stalls it.

And it’s not just about hiring “closers” or launching outbound campaigns. Most founders trip over the same patterns when building their first sales engine. Here are the top three—and how to build around them.

1. Hiring Sales Too Early… or Too Late

This mistake usually stems from urgency. Sometimes it’s, “If we just add headcount, sales will follow.” Other times, it’s investor pressure, an overflowing pipeline, or founder burnout that triggers a quick hire.

On the flip side, some founders wait too long—handling every deal themselves, buried in calls, dropping leads along the way.

Both are risky.

And the issue isn’t just when you hire—it’s who you hire and what you expect.

Startups often bring in junior reps and expect founder-level ownership. Or they hire someone “senior” with a strong résumé—but no startup mindset. No appetite for ambiguity. No instinct to roll up their sleeves.

If you haven’t nailed your ICP, value prop, and sales motion, your hire is flying blind.

Wait too long, and you become the bottleneck.

What to do instead:

Close your first 10–20 deals yourself. Let objections shape your pitch. Let rejection teach you what resonates.

If you’re stuck on positioning or pricing, get a second opinion—but don’t jump on every framework you hear. I’ve seen too many founders lose track of what’s working for them in pursuit of what worked for others. Get hands-on input from experts who are ready to roll-up their sleeves and co-build, not just comment.

Once you’ve got traction, document it—briefly. Then hire someone who can build on what’s proven to work. And make sure they’re wired for the unpredictability of startup life, not just polished process.

2. Pivoting Too Late—or Too Often

Some teams stick with what’s not working, burning time and budget trying to “grind through it.” Others pivot at the first sign of friction—cycling through strategies before any of them have a chance to stick.

Neither works.

You don’t scale chaos. You don’t learn from panic.

What to do instead:

Treat every sales conversation as feedback. If meetings aren’t converting, ask why. If the pitch falls flat, refine it—don’t toss the whole strategy.

Founders often celebrate activity—20 calls, 10 meetings—but that’s not progress. A rep who fills their calendar with the wrong people isn’t building a pipeline. They’re wasting time.

What matters is results. And understanding those results requires clarity—and good data.

Your CRM should mirror reality, not just act as a report generator. It should help you see patterns, qualify leads, and double down on what works. If your CRM isn’t helping you see those patterns clearly, it’s not just a data problem—it’s a setup problem. I break this down in more detail in How to Turn Your CRM into a Revenue Engine, where I walk through how to structure your CRM so it actually supports decision-making—not just tracks deals.

3. Incentivizing the Wrong Behavior

Most early comp plans are reactive. The team is already running—and leadership needs a way to motivate results fast. So they start tying bonuses to whatever’s easiest to measure: meetings booked, CRM updates, activity volume.

It backfires.

When you reward surface-level motion, that’s exactly what you get. Inflated pipelines. Low-fit meetings. Short-term wins that churn before they stick.

What to do instead:

Start with the only outcome that truly matters: revenue.

Sales targets should reflect what actually pays the bills and fuels growth—not activity for activity’s sake.

Yes, pipeline, meetings, and CRM notes are part of the job—but they’re not the goal.

They don’t keep the lights on.

Comp plans should drive toward revenue generated and sustained.

If you’re rewarding inputs instead of results, you’re building a culture of motion—not momentum.

Bonuses are there to motivate progress toward business goals. Not to get people to do the basics.

If you’re paying extra just to get meeting notes in the CRM, you’re solving the wrong problem.

As Korhan Erçin puts it:

“If you’re paying bonuses just to make people do the basics, you’re not managing—you’re just tracking.”

His full breakdown is worth reading if you’re building a model that aligns performance, ownership, and actual outcomes.
