Fractional HR vs Full-Time: An Honest Guide for Startups Under 50 People

One of the most common questions we hear from startup founders is: “At what point do I need a real HR person?” Usually followed by: “And do they need to be full-time?”

The answer, like most things in startup life, is: it depends. But not in a vague, unhelpful way. There are clear signals that point to the right model for your stage.

The reality of HR in small tech companies

Let us start with what usually happens. A company grows from 5 to 15 people. The CEO handles hiring, onboarding is ad hoc, there is no performance review process, and contracts are templates downloaded from the internet.

At some point, something breaks. Maybe it is a compliance issue. Maybe a key engineer quits because they felt there was no growth path. Maybe the CEO realizes they are spending 40% of their time on people tasks instead of product and customers.

That is when the search begins. And the first instinct is usually: “Let us hire a Head of People.”

When a full-time VP of People makes sense

A full-time HR leader is the right choice when:

• You have 50+ employees and HR work is genuinely a full-time job across multiple domains (recruiting, people ops, compliance, L&D, employee relations)
• You are hiring 20+ people per year and need dedicated recruiting leadership
• You have raised Series B or later and can justify a 120-180K salary plus equity
• You have multi-country operations with ongoing compliance complexity
• Your culture challenges require daily, hands-on attention (e.g., post-merger integration, major restructuring)

When fractional HR is the smarter choice

A fractional HR leader is typically better when:

• You have 10-50 employees and need senior expertise but not 40 hours per week of it
• You are hiring 5-15 people per year and need process but not a dedicated recruiting team
• Your budget is tight and a full-time VP of People would be your most expensive non-engineering hire
• You need to build infrastructure (policies, comp bands, onboarding, performance reviews) but once built, the maintenance is lighter
• You are in a single country or have straightforward employment setups

The economics

Let us run the numbers for a 25-person startup in Europe:

Full-time VP of People:

• Salary: 120,000 - 150,000 EUR
• Equity: 0.3 - 0.8% (at early stage)
• Benefits, tools, overhead: ~20,000 EUR
• Total annual cost: 140,000 - 170,000 EUR

Fractional HR leader (2-3 days/week):

• Monthly retainer: 4,000 - 8,000 EUR
• Total annual cost: 48,000 - 96,000 EUR

The fractional model costs 40-60% less. And here is the thing that most founders do not consider: at 25 people, there genuinely is not 40 hours per week of strategic HR work. A full-time hire ends up either doing operational tasks that an HR coordinator could handle for half the salary, or — worse — creating processes and policies you do not need yet.

What a fractional HR leader actually does

There is a misconception that fractional means “part-time and therefore less committed.” In practice, a good fractional HR leader:

Embeds in your team. They join your Slack, attend your leadership meetings, know your people by name. They are not a consultant who shows up quarterly with a slide deck.

Focuses on high-impact work:

• Building your hiring process and compensation framework
• Handling sensitive employee relations issues
• Setting up onboarding and performance review systems
• Ensuring legal compliance
• Advising the CEO on org design and people strategy

Does not do:

• Day-to-day HR admin (that is what an HRIS and a part-time HR coordinator are for)
• Recruiting execution (that can be outsourced separately)
• Office management

The transition path

The best approach for most startups is a staged model:

Stage 1: 5-15 employees

• No dedicated HR. CEO handles basics with a part-time operations person
• Consider a fractional HR advisor for one-off projects (setting up contracts, building an employee handbook)

Stage 2: 15-35 employees

• Fractional HR leader. 2-3 days per week, building infrastructure and handling strategic people work
• Possibly a junior HR coordinator or People Ops assistant for admin

Stage 3: 35-50 employees

• Fractional HR can transition to full-time if the complexity warrants it
• Or maintain fractional and add a full-time HR coordinator

Stage 4: 50+ employees

• Full-time Head of People is now justified
• Build out a small people team (recruiter, HR coordinator)

Red flags: when your HR model is wrong

You have fractional HR but need full-time if:

• Your fractional HR leader is consistently working more than the contracted hours
• Employee relations issues are piling up faster than they can be addressed
• You are in 3+ countries with active compliance needs
• You are hiring more than 20 people per year

You have full-time HR but should have gone fractional if:

• Your VP of People seems underutilized or is creating processes “for when we are bigger”
• The role has expanded to include office management, event planning, and other non-HR tasks
• You are paying VP-level salary for work that is mostly operational

How to choose a fractional HR partner

Not all fractional HR providers are equal. Here is what to evaluate:

1. Industry experience. An HR leader who has worked in tech companies will be 10x more effective than one from traditional industries. They understand engineering culture, equity compensation, and remote work dynamics.

2. Stage experience. Someone who has built people functions at your stage, not just managed existing ones at larger companies.

3. Embedding model. Do they actually join your team, or do they operate at arm’s length? The more embedded, the better.

4. Flexibility. Can you scale hours up or down as needs change? Are you locked into a long-term contract?

5. Scope clarity. Do they clearly define what is included and what is not? Ambiguity leads to frustration on both sides.

The bottom line

There is no universal answer. But here is the honest truth: most tech startups under 50 people do not need a full-time VP of People. They need senior HR expertise applied strategically, a few days a week.

The fractional model gives you that expertise at a fraction of the cost, with the flexibility to scale as you grow. It is not a compromise — for many startups, it is the optimal choice.
