Every growing business reaches a point where the technical capability needed to move forward outpaces what the existing team can provide. The question is rarely whether to get more resource — it's whether that resource should be a hire or a partnership. Getting this decision wrong is expensive in either direction.
The real cost of a hire
A senior engineer or technology lead with the experience to genuinely move the needle costs significantly more than the salary that appears in the offer letter. Employer National Insurance, pension contributions, equipment, software licences, management overhead, and the productivity dip during onboarding add roughly thirty to forty per cent to the headline figure. For a £75,000 salary, the true annual cost lands closer to £100,000 to £105,000.
More significant than the cost is the timeline. Finding the right senior technical person typically takes three to six months — longer for specialist roles. During that period, the work you needed them for either waits or falls to people who weren't designed to do it. And once the hire is made, the cost is largely fixed. If priorities shift, if the project completes earlier than expected, or if the business needs to reduce its cost base, unwinding a hire is slow and disruptive.
When hiring is the right answer
Hiring makes sense when the need is long-term, strategic, and requires someone embedded in the business day to day. A CTO, an engineering lead who will manage a growing team, or a senior developer responsible for a core product are examples of roles that genuinely require a full-time, permanent presence. These roles benefit from continuity, institutional knowledge, and the kind of commitment that only comes from being a direct employee.
The test is whether the capability gap you're trying to fill is one that will persist and grow over the next two to three years. If the answer is clearly yes, hiring is worth the timeline and the fixed cost.
When partnering is the right answer
Partnering makes sense when the need is specific, time-bounded, or requires a depth of specialism that a single hire can't provide. A business that needs a security assessment and remediation programme, a data pipeline built and handed over, or fractional senior engineering support while a permanent hire is found — these are all situations where a partner delivers faster and at lower total cost than a hire.
Partnering also makes sense when the required skills are genuinely specialist. Hiring a full-time penetration tester or a cloud infrastructure architect is difficult, expensive, and often results in a role that is under-utilised once the initial project is complete. Accessing that capability through a partner gives you the depth when you need it and removes the cost when you don't.
The hybrid approach most businesses land on
Most growing businesses find that the answer isn't binary. A permanent technology lead with the breadth to manage the environment and engage with the business, supported by a partner that provides specialist depth on demand, tends to outperform either approach in isolation. The lead provides continuity and strategic alignment. The partner provides capability that would be impractical to hire for. Together, the cost is predictable and the coverage is broad.
The decision framework is simpler than it often appears. Ask whether the need is permanent or episodic, strategic or specialist, and how quickly the business needs the capability to be in place. Those three questions usually point clearly in one direction — or toward the hybrid that works for your situation.
