Zevia taps Cardi B for biggest campaign to date, sells 134 million cans yearly with celebrity narrative anchor

Zevia, the zero-sugar soda brand that moved 134 million cans in 2023, launched its largest campaign to date by positioning Cardi B as the narrative anchor for brand conversation, according to Marketing Dive. The campaign puts the celebrity at the center of product storytelling rather than deploying her as a single-post endorsement.

Zevia structured the effort around Cardi B delivering what the brand calls "real talk" — positioning her as a credible voice on ingredient transparency and consumer choice. The artist appears across paid media, owned channels, and retail activations, with creative built to reflect her language and audience expectations. The brand reported the campaign as its most significant marketing investment to date, though specific spending figures were not disclosed in the sourced material.

The mechanism works because it converts celebrity reach into sustained brand context. A single Instagram post from a celebrity delivers impressions but no lasting association. A narrative campaign that positions the celebrity as the explainer of product value creates repeated touchpoints and gives the audience a reason to connect the celebrity's persona with the brand's positioning. Cardi B's audience skews younger and values directness, which aligns with Zevia's challenger stance against legacy soda brands. The brand gains permission to occupy conversation space it could not access through product claims alone.

Cardi B's involvement also solves a credibility problem endemic to better-for-you consumer packaged goods. Ingredient transparency and "clean label" messaging often read as preachy or exclusionary. A celebrity known for unfiltered commentary softens that tone and broadens the addressable audience. Zevia is not asking Cardi B to perform health evangelism; it is asking her to normalize a product choice. That distinction matters for a brand trying to move from natural food channels into mass retail.

A small physical-product brand can run the same play without an A-list talent budget. Identify a micro-influencer whose audience matches your target customer and whose communication style reinforces your product positioning. Offer them a six-month ambassador role rather than a one-off post. Structure the deal around three deliverables per month: one long-form story post explaining why they use the product, one candid video showing the product in use, and one reply-all engagement where they answer follower questions about the category. Pay a flat monthly retainer — expect $500 to $2,000 per month depending on follower count and engagement rate. Give them talking points but let them use their own language. The goal is not reach maximization; it is association depth. A customer who sees the same face explaining your product six times over six months builds a mental model you cannot buy with a single ad.

Document every result. Track referral traffic from the influencer's bio link, discount code redemptions, and direct messages mentioning their name. If you are running this play on a $3,000 quarterly budget, you are paying for 12 pieces of content and 18 weeks of sustained visibility. Compare that cost to a single trade-show booth or a regional print ad buy. The influencer becomes your sales rep, your explainer, and your credibility layer in one contract.

The broader shift here is from celebrity endorsement to celebrity infrastructure. Zevia did not rent Cardi B's audience for a day; it built a campaign architecture where she is the through-line. For a bootstrapped brand, the same principle applies: find someone your customer already listens to and make them the reason your product enters the consideration set.
