Does Your Startup Need an HR Director? A Founder's Guide to Fractional HR

Nobody googles "HR" on a good day

In all my years of doing this work, I've never once had a founder call me because things were going well.

The call comes after something. A senior hire who interviewed brilliantly and is now, four months in, quietly poisoning the team. A grievance letter - the first one, the one that makes everything feel suddenly formal. An investor's due diligence list with a section headed "People" that nobody knows how to answer. That's the honest starting point for any conversation about fractional HR for startups: founders don't wake up wanting an HR consultancy. They hit a moment.

Which means the useful question isn't "does my startup need HR?" - asked in the abstract, the answer is always a shrug. The useful question is: which moment are you in, and what does that moment actually require?

I spent 5½ years as Global People Director inside a fast-growing London AI consultancy, joining when it was small enough that everyone fitted in one room and staying while it became something considerably more complicated. I watched most of these moments arrive from the inside. Now, running Encourager, I watch them arrive in other people's businesses. The pattern is remarkably consistent.

The moments that change the question

The first bad hire that costs real money. Not a junior mis-hire - those sting and pass. A senior one. The commercial lead who never lands, the engineering manager the team routes around. By the time you act, you've spent six months of salary, a recruitment fee, and a quantity of your own attention you'll never get back. The expensive part usually wasn't the hire. It was the absence of anyone senior asking hard questions about the role before the search started.

The first grievance. Something shifts the day an employee puts a complaint in writing. Suddenly there's a process you're legally required to follow, deadlines, the word "accompanied." I've seen capable founders handle this badly not through malice but through speed - trying to fix it like a product bug, over a coffee, when what the situation needed was care, a record, and someone who's run one before.

Headcount passing roughly 25. Below that, culture is just proximity - everyone hears everything, calibration happens by osmosis. Somewhere past twenty, it stops working, quietly. Pay decisions made ad hoc for the first ten people become anomalies the next ten will eventually discover. The gap between how the founder thinks the company runs and how it actually runs starts to open. Nobody announces this moment. You notice it in retrospect.

The investor's question. If you're raising - or you're PE-backed and heading into a value-creation plan - someone will eventually ask about your people processes. Attrition, contracts, options paperwork, how performance is managed. At the AI consultancy, growth meant those questions arrived early and kept arriving. The businesses that answer them well aren't the ones with the thickest policy handbook. They're the ones where somebody senior clearly owns the answers.

Good people leaving and you can't quite work out why. This is the quietest trigger and often the costliest. Two or three regretted exits in six months isn't bad luck. It's data. But it takes someone with time and standing to actually go and find out what it's telling you.

If none of these are near you, you may genuinely not need much yet - a good outsourced contracts-and-compliance service might be enough. That's a legitimate answer, and cheaper than anything I do.

The four options, honestly compared

When a moment does arrive, founders reach for one of four responses. I've watched all four play out; only the last two involve me, so read the first two knowing I have a dog in this fight - and judge whether the reasoning holds anyway.

Do nothing and hope. Free, until it isn't. The costs arrive later and disguised - a tribunal claim from a badly-run exit, a mis-hire, an option-scheme mess discovered in due diligence. Some founders get away with it for years. The ones who don't tend to pay for several years of HR support in a single bad quarter.

The office manager absorbs it. The most common path, and the one I have most sympathy for - it usually starts as kindness, someone capable saying "I'll sort the contracts." The problem isn't their competence. It's that they've been handed accountability without authority or experience. When the first serious ER case lands, you've put your most difficult, highest-risk people work in the hands of the person least equipped to push back on you. That's not a staffing decision. It's an unmanaged risk with a friendly face.

Hire a full-time HR Director. Sometimes right - usually somewhere around 80-100 people, or when the people agenda is genuinely a full-time job. But look at the arithmetic. UK HR Director salaries typically sit somewhere between £75,000 for smaller businesses and £100,000 for larger SMEs - higher in London. Add employer's NI, pension, and probably equity, and you're easily committing north of six figures a year. With a team of 25 people, that new hire will spend half their week inventing work to justify their seat. I’ve seen startups hire an HR Director whom one of their investors' portfolio companies previously employed, two years before they actually had the problems that role exists to solve.

Fractional. Senior judgment, sized to the actual need - typically one to two days a month for an early-stage business, flexing up when something live is running. You get the person who's handled the grievance, run the restructure and answered the DD questions before, without paying for the four days a week you don't yet need. The trade-off is real and worth naming: a fractional HR Director isn't in the room every day, won't absorb all of your admin, and works best when the founder treats them as a leadership colleague rather than a supplier.

What fractional HR for a startup actually looks like

The word "fractional" makes some founders picture a helpline. In practice it looks more like this: a standing rhythm - a day or two a month embedded enough to know the people, not just the org chart - plus availability when something breaks. Sitting in on the hiring decision for the senior role. Running the difficult exit properly. Building the pay framework before the anomalies calcify. Being the person the founder can say the unsayable thing to before saying anything to anyone else.

That last one matters more than it sounds. A lot of what I actually do is help founders slow down for 48 hours - the difference between a defensible decision and an expensive one is often just sequence.

And it should shrink or end when the need does. A fractional arrangement that can't scale down honestly is just a retainer with better branding. Some of my engagements have run for the long-term; others did the defined piece of work and stopped. Both are success. (For the shape of how I run these, the Fractional & Project HR page sets it out.)
