About Sellonyx
Sellonyx helps brands make better marketplace decisions and turn them into disciplined daily execution.
E-commerce growth is rarely one isolated task. Product choice affects positioning. Positioning affects listings. Listings affect advertising. Advertising affects inventory. Operations decide whether the momentum lasts.
Sellonyx connects those decisions through senior consulting and managed support, so brand strategy and daily marketplace operations move in the same direction.
We work with brands and teams on Amazon account management, PPC, product launches, content, operations, protection, and cross-marketplace expansion.
