5 Mistakes Founders Make Before Hiring Their 10th Employee

Hitting a double-digit headcount is a milestone worth celebrating. It’s also the point where the informal, “we’ll figure it out as we go” approach to people operations starts to break down. The handshake agreements or the ad hoc PTO policy are starting to create issues.

Luckily, the mistakes founders make at this stage are avoidable with the right foundation in place. Here are the five we see most often and what to do instead.

Mistake #1: Treating HR as a “Someday” Problem

Most founders don’t ignore HR on purpose. They’re simply heads-down on product, sales, and fundraising, and HR slides to the bottom of the list. What usually happens is  a compliance question, a difficult employee conversation, or a compensation dispute forces the issue.

The fix: Put your core HR foundation in place now, while your team is still small enough to do it without disruption. That means having basic policies and clear documentation before compliance questions show up. Waiting until an issue forces a difficult conversation almost always costs more than building the foundation upfront.

Mistake #2: Winging It on Offer Letters and Policies

A patchwork of templates pulled from the internet, past employers, or well-meaning advisors might get you through your first few hires. But inconsistent offer letters, undefined PTO policies, and missing employee handbooks create confusion for your team and exposure for your business.

The fix: Standardize your core HR documents early: offer letters, an employee handbook, onboarding checklists, and the policies that govern how your company actually operates. Consistency now will save you from problems later.

Mistake #3: Guessing at Compensation

Without market data behind them, salaries end up inconsistent. A candidate mentions a number in negotiation, the budget allows a certain amount that quarter, or a figure just feels fair at the time, and each of those becomes the basis for a different offer. Over time, people in similar roles end up paid differently for reasons that have nothing to do with performance or experience. That disparity might stay invisible until someone leaves over it, and by then it’s already shaped how the team sees fairness.

The fix: Ground your compensation decisions in real market data. Knowing what a role should pay in the market helps you attract the right talent, retain your best people, and build a defensible pay structure as you scale.

Mistake #4: Skipping Team and Culture Investment

Early hires often get thrown into the deep end with little onboarding and even less thought given to how they’ll work together. As you approach ten employees, personality and communication-style differences that were easy to absorb in a five-person team start to create friction. Founders who don’t invest in understanding their people risk building a culture by accident rather than by design.

The fix: Invest in understanding how your people work and communicate before you’re ten people deep. A structured assessment or working-styles framework gives your team a shared language for their differences, so friction gets addressed early instead of quietly building into turnover.

Mistake #5: Trying to Be the HR Department Yourself

Many founders assume that hiring a full HR person is either premature or unaffordable at this stage so they take it all on themselves, alongside everything else on their plate. This usually means inconsistent execution, and HR practices that lag behind the rest of the business.

The fix: Bring in the right amount of expert support instead of taking HR on yourself. You don’t need a full-time HR hire. You need the right amount of guidance, delivered consistently, so you can build strong people practices without it consuming your bandwidth.
