It started with a simple, unplanned clip: a Barbadian spice seller propped her smartphone against a glass jar on her cluttered kitchen counter, walked viewers through her signature fish seasoning blend, and hit upload. Three days later, that unpolished home video had racked up 400,000 organic views. No professional film crew, no marketing agency, no six-figure advertising budget – reach that even a major regional supermarket chain could not purchase with a million-dollar promotional campaign.
This quiet viral success is not an isolated accident. It is part of a growing movement reshaping small business across the Caribbean, where decades-old market stall vendors are leveraging TikTok to level the playing field against multinational grocery chains that have squeezed small independent sellers out of local markets in recent years.
To unpack this unexpected trend, Guyanese-American PhD candidate Roy Naipaul spent months conducting on-the-ground interviews with vendors across the Caribbean region. Working alongside his doctoral supervisor Dr. Abdallah Elias at the International Executive School in Strasbourg, France, Naipaul set out to answer a deceptively simple question: how do cash-strapped small vendors, with no corporate backing or formal marketing budget, not just survive but grow their customer bases in the face of well-resourced retail giants? What he uncovered was not a sophisticated corporate marketing playbook, but a grassroots, community-driven model built one unscripted video at a time.
The strategy that has worked for these vendors is stubbornly simple, and defies traditional marketing logic. Budget size barely moves the needle on TikTok; what determines reach is whether viewers stay to watch an entire video. Multiple vendors described the same unwritten rule of the platform: audiences, not advertising dollars, decide which content gets amplified. The result? A single vendor with a $500 smartphone can reach just as many potential customers as a large chain with a marketing team 20 times the size of the vendor’s entire business.
The most surprising twist in Naipaul’s research is that their competitive advantage comes from what the corporate world would see as a weakness: their lack of professional polish. A doubles vendor in Trinidad found that chatting to the camera like she would chat to a regular customer while mixing her signature Indo-Caribbean dough generated far more audience engagement than any slickly produced supermarket advertisement. Customers do not want overproduced corporate content, she explained; they want to connect with real people. TikTok has upended traditional marketing rules by turning everyday creators into their brand’s most powerful advocates, with authenticity spreading organically through word-of-mouth, organic shares, clicks and views.
Vendors have intentionally leaned into characteristics that were once seen as disadvantages for mainstream marketing: thick regional accents, messy home cooking spaces, generations-old family recipes, and local creole dialects. A vendor in St. Lucia intentionally films in Kwéyòl, instantly signaling to viewers that she is a member of the local community. A Jamaican vendor calls out loyal customers by name mid-video – for example, noting she has set aside a batch of a customer’s favorite mangoes – and watches that personal touch drive shares across local social media groups.
The reach of these videos has extended far beyond Caribbean islands, exceeding even the vendors’ wildest expectations. Diaspora communities in New York, Toronto, and London have stumbled on the clips, flooding comments with nostalgia for home cooking and placing orders for specialty seasonings to be shipped internationally. Street markets that once only served customers within a few square miles now boast a global customer base.
None of these vendors had a formal guide to social media success. They learned through trial and error: posting multiple cuts of the same video, tracking which gained traction, and replicating the tactics that worked.
What stood out most to Naipaul was not one viral trick, but a repeating pattern that held across every interview: a vendor’s genuine authenticity draws viewers in, longer watch times signal to TikTok’s algorithm that the content is valuable, the algorithm pushes the video to more users, and those new viewers turn into repeat customers who follow for future content. This creates a self-reinforcing cycle: the more a vendor embraces what makes them uniquely themselves, the more their visibility grows, which in turn strengthens the personal community relationships that make the content popular in the first place.
While the organic algorithm that rewards engagement has let small vendors compete with large chains, it also carries a major, unresolvable risk. Every one of these small business owners has built their new customer base on a platform they do not control and cannot influence. A single unannounced change to TikTok’s algorithm, made to serve the platform’s own corporate goals unrelated to Caribbean small vendors, could bury their content under the same corporate marketing they have been outperforming, with no warning and no process to appeal the change. The open accessibility that let these vendors break into the global market could just as easily close the door on them, with no input from the vendors themselves.
Naipaul’s research also points to a new model for supporting small vendors that runs counter to common economic development advice. These vendors did not need paid social media training – they taught themselves, quickly and for free, by sharing tips and learning from each other’s successes. Pressuring them to adopt corporate marketing practices would backfire, because it would strip away the exact quality that makes their content work: its unapologetically non-corporate, personal feel.
For now, the story of Caribbean TikTok vendors is an unlikely underdog success. Small independent sellers are not just surviving the era of big-box supermarkets – in corners of social media, they are thriving, one unpolished video filmed with a phone propped against a spice jar at a time. Whether this momentum will last remains an open question, and it is one these vendors cannot answer on their own.
