Agency vs in-house vs fractional: choosing the right resource for your current stage

As a DTC founder, your business is only as fast as the team behind it. In the early days, “team” usually meant you, a laptop, and perhaps a versatile freelancer. But as revenue climbs toward the £1m–£5m mark, the cracks in that DIY model start to show.

The question isn’t whether you need help. It’s what kind of help will actually move the needle. Should you hire a full-time expert, double down on an agency, or bring in a fractional leader? The answer depends entirely on your growth stage and the complexity of your operations. Here is how to weigh the three most common resource models.

The agency model: scalable execution

Agencies are built for execution. If you need a team of specialists to run Meta ads, manage SEO, or design high-converting landing pages, an agency provides instant depth. You get access to a collective brain without the overhead of individual hires.

However, the trade-off is often strategic alignment. Most agencies are incentivised to spend your budget within their specific silo. They will tell you how your ads are performing, but they rarely tell you that your product margins are too thin to support that spend. An agency is a high-powered engine, but it still needs a driver to tell it where the car is going.

The in-house hire: dedicated focus

A full-time head of e-commerce or marketing director is the holy grail for many founders. You get 40+ hours a week of dedicated focus, someone who lives and breathes your brand culture, and a leader who is present for every meeting.

The challenge at the mid-market stage is the seniority gap. A truly world-class e-commerce director commands a six-figure salary plus equity. Many brands at the £1m–£3m stage end up hiring a “junior-senior”, someone who has the title but lacks the deep strategic experience to navigate a complex scale-up. You end up paying for a leader who is still learning on your dime.

The fractional leader: strategic firepower

Fractional support is the hybrid model. A fractional e-commerce manager provides the C-suite intelligence of a £120k hire for a fraction of the cost and time commitment.

Unlike an agency, a fractional lead is platform-agnostic; they focus on P&L management and commercial growth rather than just ad spend. Unlike a full-time hire, they bring cross-pollinated insights from working with multiple high-growth brands simultaneously. They sit above your agencies and internal staff, acting as the architect who ensures every resource is aligned with a 90-day roadmap.

Making the choice: the stage test

The hustle stage (under £500k): stick with freelancers or a small, niche agency. You need doers to help you find product-market fit without heavy fixed costs.
The scaling stage (£1m–£5m): this is the fractional sweet spot. You need senior strategy to professionalise the business, manage your agencies, and prepare the infrastructure for a future full-time hire.
The enterprise stage (£10m+): at this level, you likely need a full-time C-suite. The complexity and volume of the business justify the overhead of a permanent digital director or CMO.

The verdict: rent the brain, build the team

Many of the most successful DTC brands use a fractional-first approach. They rent the senior strategy to build the roadmap and hold the agencies accountable, only moving to a full-time in-house hire once the business is stable enough to support that long-term investment.
