When to Make Your First HR Hire (And What to Do Before You Do)

Almost every founder asks the same question at roughly the same moment: "Is it time to hire someone for HR?" It usually surfaces around 25 to 40 employees, when the people-related work has quietly metastasized from a few hours a month into a real, recurring drain that's pulling someone senior away from the actual business.

The honest answer is that the timing question has two parts that founders tend to collapse into one: when do you need HR work done, and when do you need a full-time HR employee to do it. Those are not the same threshold, and conflating them is what leads to expensive mistakes in both directions.

The signals that you need HR — now

You need real HR work happening (whether or not you hire for it) when you see these:

• People questions are routing to a founder or ops lead daily. Offer letters, PTO disputes, benefits questions, the occasional complaint — each one is small, but together they're a part-time job landing on your most expensive people.
• You're hiring across state lines. The first out-of-state employee triggers registrations, paid-leave rules, and policy obligations most companies don't realize they've incurred.
• You've had a near-miss. An almost-botched termination, a complaint you weren't sure how to handle, a classification you're not confident about. Near-misses are the warning before the actual incident.
• Onboarding is improvised. New hires are figuring it out themselves, and you're seeing the cost in slow ramp and early attrition.

The signals that you need a full-time HR employee

This is a higher and later bar. A full-time HR hire generally makes sense when:

• You're consistently past 50–75 employees and growing, where the volume of genuinely HR-specific work fills most of a week.
• HR has become strategic, not just operational — you need someone shaping org design, comp philosophy, and leadership development, not just running process.
• The work requires daily, embedded presence — in-person culture, complex employee relations, or a workforce large enough that issues are constant.

Below that, a full-time generalist is often a poor fit: you're paying a $70,000–$90,000 fully loaded salary for someone who may be underutilized, junior relative to the hardest problems, or both. Many companies in the 15–50 range get better outcomes from fractional HR — senior judgment at the volume they actually use — and graduate to a full-time hire later. We wrote a full breakdown of that math in fractional vs. full-time HR cost.

What to put in place before you hire anyone

Whether your next move is fractional or full-time, do these first so your eventual hire builds on a foundation instead of starting from zero:

• An HR audit. Know where you're actually exposed — classification, postings, I-9s, handbook, multi-state gaps — before you hire someone to fix it.
• A real handbook with the right state policies and disclaimers. See what belongs in your handbook.
• An HRIS that fits. Don't make your first HR hire's week-one project untangling spreadsheets. Our Gusto vs. Rippling vs. BambooHR comparison can help.
• A basic onboarding process so new hires — including your HR hire — have a real first 30 days.

The mistake to avoid

The most common error isn't hiring too early or too late — it's hiring a full-time generalist as a way to avoid thinking about HR, then assuming the problem is solved. A single junior hire can't be your compliance expert, your employee-relations investigator, your comp strategist, and your benefits administrator all at once. Be clear about which problem you're actually solving, and match the hire — or the fractional partner — to it.

If you're not sure where you land, that's exactly what a free HR assessment is for. We'll look at your size, your trajectory, and your current exposure, and tell you honestly whether you need a full-time hire, fractional support, or just a few foundational fixes.
