Zevia lands Cardi B for zero-sugar soda push, spends $15M on biggest campaign to date

The challenger brand bet on celebrity credibility over product features to break through CPG noise.

In plain words

Celebrity credibility transfers faster than product claims—small brands copy this by paying micro-influencers to share why they switched.

Zevia, the zero-sugar soda brand, launched its largest campaign in company history by partnering with rapper Cardi B, according to Marketing Dive. The effort, dubbed "Real Talk," marks a sharp pivot from ingredient-focused messaging to cultural alignment and celebrity credibility. The brand is spending more than it ever has—estimated at $15 million across TV, digital, and social—to position Cardi B not as a paid endorser but as a genuine user who chose the product before the deal.

The campaign centers on Cardi B speaking directly to camera about her switch to zero-sugar beverages. No dancing cans, no product close-ups, no ingredient recitation. Just the artist explaining why she drinks Zevia and why her audience should care. The brand shot multiple spots in which Cardi B discusses taste, health goals, and her skepticism of artificial sweeteners. Zevia is running the creative on broadcast TV during prime time, YouTube pre-roll, and Instagram feed ads, with Cardi B posting organic content to her 169 million Instagram followers. According to the company, early engagement rates on social have outperformed prior campaigns by a factor of three.

The mechanism is borrowed from a playbook that worked for brands like Vital Proteins and Olipop: celebrity-as-customer, not celebrity-as-actor. When a high-trust figure says "I already used this," the audience hears product discovery, not paid placement. Cardi B's credibility in this context comes from her documented preference for zero-sugar drinks and her vocal criticism of artificial ingredients in interviews prior to the deal. Zevia is leveraging that pre-existing narrative rather than manufacturing one. The brand also benefits from Cardi B's audience skew: younger, diverse, health-curious but skeptical of wellness marketing. That maps directly to Zevia's target: shoppers who want less sugar but distrust the taste of most diet sodas.

A small physical-product brand can run the same play without a $15 million budget or a celebrity roster. The sequence: identify a credible micro-influencer or local figure who already uses your product and has a tight, engaged audience. Reach out with a simple offer: co-create a short testimonial video in exchange for product supply and a modest flat fee—$500 to $2,000 depending on reach. Script it as "why I switched" rather than "why you should buy." Shoot it on iPhone with natural light and no branding until the final frame. Run it as a $20/day Instagram or TikTok ad targeting lookalike audiences of the influencer's followers. The cost for a 30-day test is under $1,000. The credibility gain is immediate because the endorsement feels like discovery, not advertising.

The broader pattern: challenger brands in crowded categories win by borrowing trust, not building it from zero. Zevia's bet is that Cardi B's existing credibility with her audience transfers faster than any amount of product-benefit messaging could. For a small brand, the same transfer happens at micro scale when a trusted local voice says "I use this." The play works because the audience already trusts the person. Your job is to make the endorsement feel like a recommendation, not a transaction.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.

Beyond our own Virginia Beach floor, we work with a vetted network of craft manufacturers across the US — each meeting the highest excellence in QC standards in the industry, each a specialist in its own discipline — so apparel, hard-goods imprinting, media manufacturing, packaging, and secure printing all go to the bench built for them, coordinated from one accountable hub.
