About Us
Practical People Solutions for Growing Businesses
Grigg HR helps early-stage and scaling organisations look after their people properly, stay compliant, and build the capability they need to grow — without the cost or complexity of a full in-house team.
We work with founders and leadership teams who are building something ambitious — but don’t yet need (or want) a large internal HR department.
Clear thinking. Senior judgement.
Who We Work With
We support:
-
🚀 Early-stage businesses building solid foundations
-
📈 Scaling organisations experiencing growing pains
-
👩💼 Founders and leaders who need senior support without permanent headcount
If you’re growing quickly but your people infrastructure hasn’t caught up yet — we’re built for you.
Why Grigg HR
Growth is exciting — but it can be messy.
-
Roles blur.
-
Managers struggle.
-
Attrition creeps in.
-
Compliance risk increases.
-
Founders spend evenings worrying about people issues instead of growing the business.
That’s where we come in.
​
Grigg HR exists to bring clarity, stability and commercial thinking to your people strategy — so you can scale sustainably.
Because scaling a business shouldn’t feel chaotic.
We focus on:
-
Clarity over complexity
-
Outcomes over activity
-
Commercial realism
-
Sustainable operating models
No bloated policy libraries.
No unnecessary process.
No HR theatre.
Just senior thinking, practical delivery, and measurable impact.
