The Co-Sourcing Code: How to Scale Niche Teams Without the High-Risk Hires
Executive Summary: The 1-Minute Read
- The Scaling Trap: Niche functions like Public Relations and Business Intelligence are notoriously difficult to scale using traditional hiring methods.
- The In-House Risk: Hiring senior in-house experts often fails due to resource constraints, differing expectations, and cultural misalignment with pioneer staff.
- The Outsourcing Flaw: Fully outsourcing to agencies leaves scale-ups vulnerable to account team churn and sudden dropped contracts.
- The Co-Sourcing Solution: A “co-sourcing” model pairs an internal manager with an expert external agency to guarantee continuity and high-level capability.
- The Takeaway: This hybrid approach provides scale-ups with cost-effective resilience, retaining institutional knowledge while accessing top-tier expertise.
One of the most persistent operational challenges I witness in scaling companies is figuring out how to build highly specialised, niche functions. I am not talking about your core technology, product, or finance teams. I mean the highly specific capabilities – such as Business Intelligence (BI) or Public Relations (PR) – that rely on one or two individuals with deep, expert skill sets.
At the start-up stage, these functions are rightly deprioritised. But as your business proves its product-market fit and begins to scale rapidly, having robust data or a proactive media presence becomes critical. The problem is that building a highly specialised team requires highly specialised people, and traditional hiring models rarely work. Over the years, I have grappled with this issue and endured several costly failures. Through trial and error, however, I have developed a hybrid formula that has not let me down since.
The Problem with In-House Empires
Historically, I attempted to build out BI teams the traditional way: hire an experienced manager, task them with building a team, and ask them to develop the infrastructure alongside our existing tech function. It failed every time.
The issue lies in the transition from corporate to scale-up. Often, senior hires from corporate backgrounds are eager to build an empire but are reluctant to roll their sleeves up for the long term. In a founder-led scale-up, resources are tight, and every pound (£) spent needs to demonstrate a clear return on investment. The newly hired BI manager feels pressured to prove their worth from scratch but complains about a lack of resources. Meanwhile, legacy management – who built the business on grit and intuition – views the new department as an unnecessary drain on cash. The inevitable outcome? The manager leaves. You are then forced to hire a replacement who will inevitably dislike the previous manager’s toolstack, demanding that the initial work be completely redone. The cost in both time and capital spirals out of control, making the internal case for a BI team even harder to justify.
The Volatility of Total Outsourcing
To avoid the expense of an in-house hire, I took a different approach with PR. Recognising that a scale-up can rarely justify more than one full-time PR specialist, I outsourced the function entirely to an agency.
For a couple of years, this worked seamlessly. We had a team of highly skilled professionals who understood our business and felt like part of our internal team. Then, staff turnover hit the agency. Institutional knowledge was lost overnight, and the replacements failed to deliver the same quality. As a client, you have zero control over the personnel allocated to your account.
The final blow came when the agency abruptly dropped us to service a competitor with a much larger budget, leaving us completely in limbo. Outsourcing had seemed cost-effective initially, but the volatility proved far too dangerous for a growing business.
The Co-Sourcing Sweet Spot
Stuck between the rigidity of in-house hires and the volatility of agencies, I began testing a hybrid approach known as co-sourcing. A co-sourced model pairs an internal manager with an external specialist so you retain control, continuity, and capability.
When moving my PR account to a new firm, I explicitly stated that I would no longer be beholden to a single agency, but that I still valued their strategic support. Together, we hired a more junior, in-house PR manager who had solid experience handling day-to-day media enquiries. The external PR agency helped me scope the role, participate in the hiring decision and assist in onboarding the new hire.
This hybrid team has flourished. The business gained immediate resilience: if the agency moves on, I have a capable internal manager to maintain momentum; if the internal manager leaves, the agency provides immediate cover and continuity. Crucially, this setup cost virtually the same as a purely outsourced model.
A Blueprint for Scalable Expertise
I later applied this same co-sourcing strategy to build out a BI function. I partnered with an external BI advisory firm to build and maintain the heavy infrastructure of the data warehouse. Simultaneously, we hired an internal BI manager to act as the commercial interface—scoping the business’s requirements and collaborating with the external team to deliver the reports.
If you are looking to scale niche functions, stop treating the decision as a binary choice between in-house and outsourced. A co-sourced model gives scale-ups the best of both worlds. The right advisory partners will embrace this structure to build a sustainable, long-term relationship, helping you embed vital competencies without holding your business to ransom. It also helps achieve the small, practical proof points that persuade pioneer teams to adopt new ways of working – an idea I cover in my article Beyond Good Enough: A CEO’s Guide to Implementing Change in a Flourishing Scale-Up
Practical Rules for Executing Co-Sourcing
If I break it down, I see 5 clear steps to executing a co-sourcing strategy:
- Scope the internal role around commercial interface and continuity (day-to-day enquiries, stakeholder management, prioritisation).
- Use the external partner for high-skill delivery (data engineering, PR strategy, media relationships) and for rapid capability build.
- Involve the external team in hiring and onboarding to ensure the internal hire is fit for partnership, not just execution.
- Contract with clear SLAs and an exit/transition plan so knowledge transfer is preserved if the external partner leaves.
- Treat co-sourcing as a deliberate, time-bound capability programme: plan to transition more capability in-house as the company matures.
The Right Partner
Co-sourcing is not a silver bullet. Some advisory firms will try to trap you with long, dependent relationships; the right partners will help you build internal capability and earn long-term work on merit. But having used this model repeatedly for BI and PR, I can say it reliably gives scale-ups resilience, focus, and a path to embed specialist functions without the high commercial risk of a single hire or the instability of full outsourcing.
