StackBuilders gives growth-stage startups access to senior talent acquisition expertise, delivered on a fixed-fee, fractional basis. Audit your hiring, implement your ATS, or bring in ongoing TA leadership. No agency markup. No long-term lock-in.
You're hiring fast enough to feel the pain, but not big enough to justify a Head of TA at £100k+. You end up relying on agencies for volume and gut instinct for strategy. Neither scales.
StackBuilders fills that gap. Clear outputs, transparent fees, and the experience of someone who has built TA functions from scratch at companies like HiBob, Starling Bank, and Multiplier.
Every engagement is scoped clearly upfront. You know exactly what you're getting, what it costs, and what happens at the end.
Not sure what kind of support you need? The TA Diagnostic is a structured half-day audit of your entire talent acquisition function. It tells you exactly what's working, what isn't, and where to focus first. A written 90-day action plan is delivered within five working days. Most engagements start here.
Platform selection, configuration, integrations, and team training, all designed around your actual hiring process. Whether you're choosing for the first time or fixing a broken setup.
Ongoing strategic TA leadership on a monthly retainer. Hiring manager coaching, process governance, metrics, and board-level reporting, without the full-time headcount.
A documented, repeatable hiring process built around your roles and culture. Interview frameworks, scorecards, comms templates, and ATS alignment, so every hire runs the same way.
I've spent over a decade building talent acquisition functions for some of the UK and Europe's fastest-growing technology companies. I know what a well-functioning TA operation looks like at every stage. I also know the shortcuts founders take that cost them later.
StackBuilders exists to give growth-stage companies access to Director-level TA expertise without the full-time hire, bringing the speed, accountability, and commercial focus that comes from working independently.
If you know something about your hiring isn't working but aren't sure what, the TA Diagnostic is the fastest way to get clarity. If you've been approached about an ATS project and want independent input before committing, start there too.
