Brand Advocacy Isn't a Channel. It's Infrastructure.

Lululemon crossed $1 billion in revenue in 2011 – built almost entirely on community-led marketing, not paid media. Local ambassadors, in-store yoga classes, Sweatlife events. Word of mouth at scale.

That story opened Show off Your Stack: Advocacy as Infrastructure, Duel's panel at their NYC headquarters the night before the Lead Summit.

Paul Archer, Co-Founder & CEO, Duel and host of Building Brand Advocacy, sat down with Nathalie Banker, Head of US Communications and Advocacy at No7 Beauty, with contributions from David Baker, Chief Revenue Officer at Beekman 1802.

The conversation centered on one idea: Brand Advocacy isn't a marketing channel sitting next to paid and PR. It's the infrastructure the rest of your channels run on.

Here are the top three insights from the panel, and what they mean for how you build the next era of growth.

1. Generosity is acquisition spend, not cost of goods

Most brands cap product gifting because their finance team treats it as an $100 cost on the P&L.

That math is wrong before it starts. The actual cost is COGS, which is usually a fraction of retail. The line item it sits in isn't inventory. It's acquisition.

"What's your cost of goods on this?" Paul said, walking through the typical CFO conversation. "This sits in the same line as your ads."

Once you reframe gifting that way, the ceiling moves. Lululemon proved it. Before they hit a billion in revenue, their stores were targeted on community giveaways and fitness classes facilitated, not just transactions. When stores missed numbers, leadership asked: Did you give away enough product?

Nathalie put the same instinct in plainer terms: "Be generous with your products for those people who are your Advocates. Don't be stingy."

Beekman 1802's David Baker added, "The worst that can happen is someone tries to get one up on you and asks for a free product. But if you believe in your product, they're going to talk about it."

The brands afraid to give products away are the ones still framing Brand Advocacy as a cost. The brands scaling are framing it as acquisition.

2. The macro / micro / nano framework is dead

Paul made the case that the entire influencer marketing industry has built itself on the wrong lens: follower counts.

"More than 90% of what you see on TikTok or Reels comes from people you don't follow," he said. "The algorithm is deciding what you watch, not who you follow. But that whole business is based on how many followers you've got. So it's effectively 90% wrong."

The better lens: amateur vs. professional.

Professionals are the creators who make a living on content production. This is a B2B relationship. They have agents, expect commercial terms, negotiate rights. You buy their craft.

Amateurs are your customers who happen to post. This is a community relationship. They look more like your loyalty program than your media buy. They engage for product, access, and belonging.

"They've got more in common with your loyalty program than they do with your macro creators, even though they look the same," Paul said.

The implication: brands trying to manage both groups inside one program – or worse, the same workflow – are doing both jobs poorly.

At its core, the foundation of why advocacy works is bigger than any framework. It always starts with a person, not a metric. It’s about building an authentic community, and using technology to scale.

3. Brand Advocacy is full-funnel infrastructure

Brand Advocacy doesn't live in awareness. It runs the full purchase journey.

At the top of the funnel are culture creators. The macro voices who shape what your brand stands for. You don't pay them in discount codes – you pay them in access, story, and proximity.

In the middle, you have quality content creators. The’re authentic, polished, and brand-aware. Their content can go straight into paid retargeting.

No7's Pro Artist launch ran on exactly this play: roughly 100 mid-tier makeup creators (around 90k followers each) were gifted simple branded mailers, with no script. A few went viral. The brand sold out so fast that the supply chain head asked Nathalie to "let me know the next time we're going to go viral."

At the bottom of the funnel are commercial creators. The affiliate and conversion layer. You love them proportional to the converting traffic they send.

That infrastructure scales. No7's Duel-powered Brand Advocacy program, launched in January, and within months it hit 3,000+ community members and 4,000+ social posts in the US alone. Organic social engagement rose 30%.

At Beekman 1802’s Brand Advocacy Program, the Kindness Krew (also built on Duel) replaced traditional paid review services entirely. When Beekman launched at Ulta, they routed review requests through their existing Advocates instead of buying through Bzzagent. The result: 250 five-star reviews in launch week, and one of Ulta's fastest-selling velocity products.

"That couldn't happen in year one with our size," Baker said. "And it couldn't happen until we bought into Advocacy as infrastructure."

The takeaway

Brand Advocacy isn't another channel to manage next to paid, retail, and influencer.

It's the layer underneath them all. The foundation that makes every other channel cheaper, faster, and more credible.

The brands treating Brand Advocacy as a line item run it as a campaign. The brands treating it as infrastructure run it as an operating model. The first will report quarterly. The second will compound for a decade.
