I’ve built an HR function from the ground up. Not conceptually — literally. At a PE-backed consulting firm with fewer than 100 employees, I walked in as the Head of HR to find critical compliance gaps across 10+ states, no documented processes for anything from onboarding to termination, compensation decisions made without market data, and an employee handbook that hadn’t been touched in years. Everything needed work.

That experience — plus 20 years of building and rebuilding HR functions at organizations from Stanford to McKesson to T-Mobile — taught me something that most growing companies learn the hard way: the hardest question when building HR from scratch isn’t what to build. It’s what to build first.

Because when everything needs attention, the temptation is to either try to fix it all at once (which overwhelms your team and produces shallow results) or to fix whatever is loudest today (which is reactive, not strategic). Neither approach works. What works is a deliberate sequence — building the right things in the right order so that each layer supports the next.

The Order That Works

After building and assessing HR functions across industries and company sizes, I’ve found that the same general sequence holds regardless of whether you’re a 60-person startup or a 400-person company that’s been winging it. The specifics get calibrated to your stage, but the order is consistent.

Layer 1: Compliance and risk (Months 1–2). This comes first because it’s the only category where getting it wrong creates legal and financial exposure. Employee classifications (exempt vs. non-exempt, contractor vs. employee), I-9 documentation, multi-state tax filings if you have remote workers, workers’ compensation coverage, required postings, and a current employee handbook reviewed by employment counsel. This is more complex than it was even a few years ago — if you have employees in multiple states (and most growing companies with remote or hybrid workers do), you’re navigating different paid leave accrual rules, minimum wage rates, posting requirements, and reporting standards in every jurisdiction. None of this is glamorous. All of it is non-negotiable. When I arrived at a PE-backed firm, I found tax filing errors across 10+ states and over $100K in unemployment insurance overpayments. That’s the kind of exposure that sits quietly until it doesn’t.

Layer 2: Employee lifecycle basics (Months 2–4). Once the compliance foundation is solid, build the systems that govern how people enter, exist within, and exit your organization. A structured onboarding process with 30/60/90-day milestones. A consistent approach to performance conversations (this doesn’t have to be a formal annual review system yet — but managers need a shared expectation for how and when they give feedback). A documented termination process so separations are handled consistently and legally. And an offboarding process that protects institutional knowledge and collects honest exit data.

Layer 3: Compensation structure (Months 3–5). You can’t keep making pay decisions one-off based on what candidates ask for and what feels right. A compensation philosophy tells your organization how you intend to pay — at market, above market, below market with equity upside, whatever fits your business model. Salary bands give managers a framework for making pay decisions. Market benchmarking provides the data to know whether your offers are competitive. This layer is more urgent now than it was even two years ago: pay transparency laws are accelerating rapidly, with more than a dozen states now requiring salary ranges in job postings and the EU Pay Transparency Directive taking effect in mid-2026. A defensible compensation structure isn’t just good management practice anymore — it’s increasingly a legal requirement. This layer also addresses pay equity, which becomes more scrutinized with every new transparency mandate.

Layer 4: Recruiting infrastructure (Months 4–6). Reactive hiring — a role opens, someone posts a generic job description, and the first available candidate gets hired — is one of the most expensive operational inefficiencies in a growing company. Every bad hire costs 50–200% of the role’s salary. Building real recruiting infrastructure means structured interview processes with consistent evaluation criteria, hiring manager training so interviewers know what to look for, an applicant tracking system that’s actually used, and an employer brand that helps the right candidates find you. One emerging consideration: if you’re using AI-assisted recruiting tools for screening, scheduling, or candidate evaluation, be aware that several states are implementing regulations requiring disclosure, bias audits, or consent for AI use in employment decisions. Build your recruiting process to be defensible from the start, not retrofitted for compliance later.

Layer 5: Performance management and development (Months 6–12). Notice this isn’t first. You need the foundation in place before you build the systems that help people grow. A performance management framework that managers will actually use (which means it has to be simple enough to sustain). A development planning process that connects individual growth to organizational needs. And the beginning of a talent review conversation — even if it’s informal at first — so you know who your strongest contributors are, who’s at risk of leaving, and where your leadership pipeline is thin.

Two Mistakes That Derail the Build

Mistake #1: Starting with the HRIS. I see this constantly. A CEO or HR leader decides the first step is buying an HR technology platform, because it feels like the most tangible action. But an HRIS is an enabler, not a foundation. If you don’t have documented processes, buying software to automate them is just automating chaos. You end up spending $30K–$80K on a platform that’s configured around processes that don’t exist yet, and two years later you’re either not using half the features or re-implementing from scratch. Build the processes first. Buy the technology to support them.

Mistake #2: Hiring before you have a plan. Your first HR hire is critical, and getting the profile wrong is a setback that takes a year to correct. If you hire a junior generalist when you need strategic leadership, you’ll have someone who can process paperwork but can’t build systems. If you hire a strategic leader when you need tactical execution, you’ll have someone frustrated by the volume of administrative work that needs to happen before strategy is relevant. The right first hire depends on where you are in the layered roadmap above — which is why an assessment of your current state is the best investment you can make before you hire anyone.

Your First HR Hire — Getting the Profile Right

The question I get most often from CEOs is: “Should my first people hire be an HR generalist, a recruiter, or something else?” The honest answer is that it depends on your most pressing need and your current volume, but here’s a general framework:

If you’re hiring 20+ people per year, your first hire should probably be a recruiter or recruiting coordinator. Volume recruiting is a full-time job, and having your managers source and screen candidates is an expensive misuse of their time.

If you’re under 20 hires per year but have compliance gaps and no HR infrastructure, an experienced HR generalist (5–8 years, not entry-level) who can both build systems and handle day-to-day operations is usually the right profile. Pair them with employment counsel for the legal questions and an external advisor for the strategic direction they’re not yet equipped to provide.

If you need strategic direction but can’t justify a full-time executive, a fractional CPO or HR advisory relationship provides senior-level guidance at a fraction of the cost. The advisor helps set the strategy and build the frameworks while your internal HR person executes.

Three Things You Can Do This Week

1. Map your current state against the five layers. For each layer — compliance, employee lifecycle, compensation, recruiting, performance management — give yourself an honest rating: solid, partially built, or doesn’t exist. This five-minute exercise tells you immediately which layer needs attention first and whether your current efforts are in the right sequence.

2. Check your three highest-risk compliance items. Are your employee classifications defensible? Is your handbook current and reviewed by counsel? Are you properly registered in every state where you have employees? If you’re uncertain about any of these, that uncertainty is itself a data point — and it suggests Layer 1 needs immediate attention.3. Calculate the cost of your last bad hire. Add up the recruiting costs, the onboarding investment, the salary paid during the period they were underperforming, the management time spent trying to coach them up, the severance or unemployment costs, and the impact on the team. For most mid-level roles, you’ll land somewhere between $75K and $200K. That number is the business case for building recruiting infrastructure.

If this roadmap resonates, the HR Department Assessment is designed to tell you exactly where you stand across all seven HR domains and give you a prioritized buildout plan calibrated to your size and stage. It’s the diagnostic that turns “everything needs work” into “here’s what to build first, second, and third.” Three tiers are available by company size, starting at $5,000.
