We hear a lot about the Big Five in retail media: Amazon, Walmart, Instacart, Target, and Kroger. And fair enough—they represent 90% of the addressable media market across onsite and offsite placements. They’ve got the traffic, the tooling, the infrastructure—and the eyeballs. But they don’t have everything.
These behemoths are not always the right place for every brand, every product, or every campaign. And when it comes to building brand equity, tapping specific communities, or launching high-intent activations tied to seasonal or category moments, smaller retail media networks can sometimes outperform the big guys in all the ways that matter.
Niche doesn’t mean small
Niche retail media networks aren’t niche because they’re irrelevant. They’re niche because they go deep, not wide—and that’s exactly what certain brands need.
These aren’t fringe players. Most are category captains. They have loyal, purchase-ready audiences, powerful first-party data, and category authority. And more critically, they’re building real retail media offerings, from custom ad units to loyalty-linked segmentation to fully formed networks with onsite, offsite, and in-store activations.
Some are newer to the game than others. Some require more manual setup or don’t yet offer self-serve dashboards. But most have matured faster than expected—and for the right brands, the payoff is real.
It reminds me of the early 2010s when I was testing non-Google paid search platforms like eZanga and 7Search (anyone remember those?). The volume wasn’t there, but I wasn’t expecting it. I was chasing relevance. With niche RMNs, you’re not looking for scale—you’re looking for alignment. And for brands that don’t fit neatly into an Amazon taxonomy, or want to break through a cluttered category, these platforms offer a powerful way in.
