Most founders frame this as a cost question. It isn't. It's a capability question. The real ask is: can you build and retain the specialist depth you need, fast enough to compete, without the overhead eating the margin you're trying to grow?

The answer depends on your stage, your category, and what kind of marketing work actually moves the needle for your brand. Here's how to think through it.

What in-house actually means

In-house doesn't mean one marketing hire. It means building a team with specialist capability across the channels that matter for your business. For a DTC brand doing meaningful revenue, that's typically: email and CRM, paid social, paid search, content and creative, and some version of brand and strategy oversight.

That's five to seven specialists, each with real depth. The salary stack for a competent team at that level is £300,000 to £500,000 a year before management overhead, tools, and the cost of mistakes while the team learns your brand and category.

Most brands that say they want to go in-house aren't actually building that. They're hiring one or two generalists and calling it a team. Generalists are useful. They can't replace specialists at the channel level where DTC performance is actually won or lost.

What agency actually means

Not all agencies are the same and the category spans a wide range. A full-service DTC agency with specialist capability in paid, email, Shopify, and creative is a different proposition to a general digital agency that handles social media and some Google Ads.

The relevant question isn't agency vs in-house. It's whether you can find and afford the right specialists for your stage, whichever model you use.

Agencies that work well for DTC brands typically offer: channel specialists with live accounts across multiple brands, meaning faster iteration and fewer expensive mistakes; shared infrastructure (analytics, creative, tools) that would cost significantly more to build internally; flexibility to scale up or down without the fixed cost of headcount; and a working relationship with aligned incentives, where performance drives retention.

The model breaks down when: the agency is managing too many accounts per person, strategic thinking is thin or generic, creative is templated, and the relationship becomes a reporting exercise rather than active management.

Where in-house works better

Brand strategy and identity. The closer you are to the brand, the better the work tends to be. A brand that knows exactly who it is and can brief clearly tends to produce better creative in-house than it can brief an agency to produce.

Content and community. If your brand is built on founder-led content, organic social, or a tight community relationship, the person running that needs to be embedded. You can't outsource authenticity.

Customer experience. CRM, retention, and post-purchase communication often benefit from someone who lives inside the brand and knows the customer base intimately. This is the area where in-house can genuinely outperform agency, especially for brands with complex or high-LTV customer relationships.

Where agency works better

Paid media. The difference between a skilled paid media specialist who manages multiple DTC accounts and a solo in-house hire who owns the channel is significant. Speed of learning, access to cross-account data, platform relationships, and depth of testing experience all favour agency for most brands below £20M revenue.

Klaviyo and CRM infrastructure. Building and optimising a full Klaviyo programme requires more than knowing how to send emails. Flow architecture, segmentation logic, deliverability, and integration with the Shopify stack are all technical areas where a specialist with deep experience delivers results faster than someone learning on the job.

Creative at volume. DTC paid media in 2026 requires a high volume of creative output to stay competitive. An agency with a creative production capability, UGC sourcing, and testing frameworks at scale is hard to replicate internally unless you're investing heavily in the function.

The hybrid model most mature DTC brands settle on

The brands we work with longest tend to land on a structure that looks roughly like this: one or two strong internal hires who own brand, content, and customer relationship; and an agency partner handling the performance channels, Klaviyo, and creative production.

The in-house team owns the brand relationship and the community. The agency drives performance and brings specialist depth on the channels that require it. The internal lead co-ordinates rather than manages each specialist function directly.

This structure works because it puts the brand knowledge where it belongs — inside the company — and the technical execution where it works best: with specialists who do this every day at scale.

What stage you're at changes the answer

Under £2M revenue: your marketing budget is limited and hiring even one decent paid specialist full-time is a significant commitment. An agency with a manageable retainer and specialist capability gives you more per pound spent at this stage.

£2M to £10M: you likely have a small internal team or a founder doing more than they should be. This is usually when the case for agency support becomes clearest. The channel complexity has grown faster than the internal capability.

£10M and above: you probably have some in-house capability already. The question becomes where agency remains the right choice and what can be moved in-house as the team scales. For most brands, paid and Klaviyo stay with specialists. Brand strategy, content, and community moves in-house or to a brand-focused partner that understands the relationship, feeds brand context, and coordinates the creative pipeline. That structure scales well to £10M and beyond before it needs to change.
