In the early stages, hiring is often driven by founders or senior leaders. As a business grows, companies typically adopt one of two well‑established approaches: 

• Building an internal Talent Acquisition (TA) function 
• Partnering with an external recruitment agency 

Both models deliver strong outcomes when aligned with business stage, hiring volume, and growth trajectory. The decision isn’t about which approach is “better,” but which one best suits the organisation’s current and future needs. 

As technology companies scale, hiring becomes more complex. Technical skill sets evolve, competition intensifies, and workforce planning becomes more strategic. Many leaders begin to reassess whether their existing hiring structure is designed to support their next phase of growth. 

Before exploring additional models, it’s useful to understand how different approaches operate in high‑growth environments. 

Internal Talent Acquisition Teams 

Building an internal TA function offers clear advantages: 

• Deep cultural alignment 
• Strong stakeholder relationships 
• Long‑term workforce planning 
• Control over employer branding 

However, for high‑growth tech businesses where hiring demand fluctuates, internal teams may experience challenges such as: 

• Fixed Cost Structures 

TA teams involve salaries, tools, systems, and ongoing operational investment. During slower periods, capacity may exceed demand; during rapid growth, teams may need to scale quickly.

• Technical Ramp-Up Time 

Emerging tech roles often require highly specialised market knowledge. Internal teams may need time to build new pipelines as technical requirements evolve. 

These are not limitations of capability, simply reflections of how dynamic and competitive the technology talent landscape has become. 

Traditional Recruitment Partnerships 

Traditional agency recruitment remains a critical and highly effective solution, particularly when businesses need: 

• Hard‑to‑fill or niche skills 
• Confidential or senior hires 
• Immediate support for urgent roles 
• Access to passive candidate networks 

Strong recruitment partners, such as Harrison McMillan, invest in relationships, market intelligence, and long‑term client understanding. When aligned well, traditional recruitment consistently delivers speed, quality, reach, and expertise. 

This model continues to be an essential component of the hiring ecosystem for high‑growth technology companies. 

When Growth Outpaces Hiring Infrastructure 

For many scaling tech companies, the challenge isn’t choosing between internal teams or agencies, it’s ensuring the hiring structure adapts as the business evolves. 

What works at 20 employees may not suit an 80‑person organisation. Steady hiring phases require different support structures than rapid scale‑up periods. 

Rather than replacing one model with another, many organisations are adopting blended approaches, combining internal capability, traditional recruitment partnerships, and new flexible support models. 

At Harrison McMillan, we partner with clients across both traditional recruitment and flexible solutions such as Hybrid RPO and Recruiter on Demand, helping businesses access the right structure at the right time. 

Part 2 explores how these models complement recruitment strategies to support efficient, scalable growth.
