Every growing company hits a moment where the CEO looks up from whatever people problem just consumed their afternoon and thinks: “We need an HR person.”
The trigger is different for everyone. Maybe it’s the third compliance question this month that nobody can answer. Maybe it’s a termination that went sideways because there was no documentation. Maybe it’s realizing that the COO has been running payroll, managing benefits enrollment, and mediating a team conflict — all before lunch — and none of that is their actual job.
The instinct is right. What happens next usually isn’t. The most common mistake I see isn’t waiting too long to hire HR. It’s hiring the wrong profile for the wrong reasons at the wrong stage — and ending up twelve months later with someone who’s either overwhelmed by work they weren’t hired to do or frustrated by a role that doesn’t match their skills.
The decision isn’t simply “should we hire an HR person.” It’s “what kind of HR support does our company actually need right now?” Those are very different questions, and they lead to very different answers.
The Three Signals That You’ve Waited Long Enough
Before we get to the “who,” let’s establish the “when.” There’s no universal headcount trigger, despite what you’ll read online. The conventional wisdom says you need your first HR hire at around 50 employees, and that’s a reasonable starting benchmark. SHRM data shows the average HR-to-employee ratio is about 2.57 HR staff per 100 employees across all organizations, with smaller companies running higher ratios because a minimum amount of HR capacity is needed regardless of size.
But headcount alone is a poor indicator. I’ve worked with 80-person companies that had straightforward people needs and 40-person companies that were a compliance disaster across six states. The real signals are about complexity, not size:
Signal 1: Leadership bandwidth is being consumed by people operations. If your CEO, COO, or founders are spending 10 or more hours per week on HR-related decisions — hiring, compensation, employee issues, compliance questions, benefits administration — that’s a quarter of their time going to work that isn’t growing the business. Track it for one week. The number is almost always higher than people estimate.
Signal 2: Compliance exposure is accumulating. Multi-state operations, employee misclassification risk, an outdated or nonexistent handbook, inconsistent termination practices, no I-9 audit trail. Any of these individually is manageable. When three or four stack up, you’re carrying risk that grows with every new hire.
Signal 3: People decisions are being made without criteria or consistency. Compensation is set by negotiation rather than market data. Promotions happen because someone asked, not because they met defined criteria. Performance issues are handled differently depending on which manager is involved. When every people decision is ad hoc, you’re building an organization on a foundation that won’t scale.
If two of these three signals are present, you’re past the point where doing nothing is free. The cost is just hidden — in leadership time, in turnover you can’t explain, in the compliance exposure you haven’t quantified yet.
The Four Options (and When Each One Fits)
This is where most companies make the critical mistake: they default to posting a job for an “HR generalist” without asking whether that’s actually the right move. There are four distinct options, and the right one depends on your stage, your volume, and what’s actually breaking.
Option 1: An experienced HR generalist (5–10 years of experience). This is the right first hire for companies under 150 employees that need someone to build and run the basics — compliance infrastructure, employee lifecycle processes, benefits administration, and day-to-day employee relations. The key word is experienced. An entry-level HR coordinator cannot build systems; they can only operate ones that already exist. You need someone who has built an onboarding process before, who knows what a defensible termination file looks like, who can set up a benefits plan and manage open enrollment. Budget $75K–$100K in total compensation for the right profile, depending on your market.
Option 2: A recruiter or recruiting coordinator. If your primary pain point is hiring volume — you’re adding 20 or more people per year — and your compliance and employee relations infrastructure is reasonably stable, your first hire might not be a generalist at all. Recruiting is a full-time job that most managers are doing badly on the side. A dedicated recruiter handles sourcing, screening, interview coordination, and offer management, freeing managers to focus on the evaluation rather than the logistics. This works best when someone else (even a fractional advisor) is handling the strategic and compliance dimensions.
Option 3: A fractional HR executive or advisory relationship. If what you need is strategic direction — someone to set the people strategy, advise on complex situations, mentor a junior HR person, and help you make the eventual full-time hire — a fractional CPO or HR advisory engagement provides senior-level expertise at a fraction of the full-time cost. This model works especially well between 50 and 300 employees, and it pairs naturally with a generalist or recruiter who handles the day-to-day execution. The strategic leader sets direction; the internal person executes.
Option 4: A combination. The most effective model I see at companies between 75 and 250 employees is a strong internal generalist paired with an external strategic advisor. The generalist handles the daily operational work. The advisor provides the strategic framework, handles the complex judgment calls (restructuring, executive compensation, difficult terminations, M&A preparation), and helps build the infrastructure that the generalist will eventually manage independently. This combination often costs less than a single senior HR hire and produces better results because you’re getting both tactical execution and strategic depth.
The Hire That Sets You Back a Year
Let me describe the scenario I’ve seen play out at least two dozen times. A CEO decides they need HR help. They post a job for an “HR Manager” and hire someone with 3–5 years of experience at a large company. This person knows how to operate within an existing HR infrastructure. They know how to use Workday, how to process a performance review in a system that already exists, how to follow a termination procedure that someone else wrote.
What they don’t know is how to build any of that from scratch. They don’t know how to write a compliant handbook for a multi-state operation. They don’t know how to design a compensation philosophy. They’ve never set up a benefits plan from an empty spreadsheet. They’ve never been the only HR person in the building.
Six months in, the CEO is frustrated because the HR hire hasn’t solved the strategic problems. The HR person is frustrated because they’re being asked to do work they weren’t trained for. And the company has lost a year of progress while paying for a role that wasn’t right for the stage.
The antidote is to be honest about what you’re hiring for before you write the job description. Are you hiring someone to build, or someone to operate? Those are different people with different skill sets, and they rarely overlap at the 3–5 year experience level.
Three Things You Can Do This Week
1. Track your leadership team’s HR time for five business days. Every people-related question, decision, conversation, or crisis that lands on someone’s desk outside of HR. Be specific — log it. The total will tell you whether you’re dealing with an inconvenience or a strategic drain.
2. List your top three compliance concerns. Are you properly classifying employees and contractors? Is your handbook current and reviewed by counsel? Are you registered and compliant in every state where you have workers? If you can’t confidently answer all three, that’s data that informs the urgency and the profile of your first hire.
3. Define the job before you write the job description. Make a list of every people-related task that needs to happen in your company. Separate it into two columns: daily operational work (payroll, benefits, onboarding, compliance tracking) and strategic work (people strategy, org design, compensation architecture, succession planning). The balance between those two columns tells you whether you need a generalist, an advisor, or both.
Getting your first HR hire right is one of the highest-leverage decisions a growing company makes. Get it wrong and you lose a year. Get it right and you build the foundation that every future people decision rests on.
An HR Department Assessment can help you understand exactly where your people function stands today, which gaps are most urgent, and what profile your first (or next) HR hire should be. It’s the diagnostic that makes the hiring decision clear instead of guesswork.
