When should a startup hire a fractional head of sales?

Short answer: when sales has become your bottleneck but a full-time sales leader would be premature. Here's how to tell.

Signs it's the right time

• You've closed a handful of deals but couldn't explain to a new hire how. The wins came from your instinct and your network, and neither is written down.
• You're spending founder hours on unqualified leads because there's no qualification process filtering them.
• Deals go quiet and you don't know why. No one is mining the lost deals for the reason.
• You're about to make your first sales hire and there's nothing for them to inherit: no playbook, no CRM discipline, no onboarding plan.
• Investors are asking about your repeatable sales motion and you have anecdotes instead of a system.

Signs it's too early

If there's no product a customer can use, or no customer conversations happening at all, sales leadership won't fix that. And if you're pre-PMF, hiring anyone to sell instead of you is usually a mistake: those early conversations are how you find out what the product should be, and that learning has to land in the founder's head, not a contractor's.

But too early for a hire is often exactly the right time for a system. At the earliest stage the right model is a coach who designs the motion, preps the calls with you, and reviews what happened, while you stay the one selling. That's a fraction of the cost of a bad hire and none of the risk.

The stage where fractional fits

In my practice that's pre-PMF up to about €1M ARR, for technical founders selling technical products. Further along, I run deals myself. Earlier, I build the system and coach the founder to run it. Which lane you're in depends on your deal history, and I'll tell you honestly if you're not sure.
