At Sellonics, we're more than just another agency. We're the growth partner that serious Amazon brands turn to when they're done playing small. We help brands move beyond just selling and start building something real: sustainable profitability, stronger operations, and predictable growth across Amazon and beyond.
To give ambitious brands the expert, data-driven e-commerce growth that was previously out of reach, without the bloated retainers and empty promises that come with most agencies. We work with sellers who are ready to grow and we make sure they do.
Over $200M in Amazon revenue generated. 150+ brands served. A 93% client retention rate. Those numbers don't happen by accident. They happen because we obsess over the things that actually matter to your business.

If we don't grow your revenue, you don't pay.
Your account is handled by people who have done this before, not someone learning the ropes at your expense.
You will always know exactly how your account is performing, in plain language you can understand.
We turn away brands we can't genuinely help. If we take you on, it's because we know we can deliver.
We cover everything your Amazon business needs to grow and keep growing:
We take complete ownership of your account so you can focus on your business, not the platform.
Smarter campaigns, tighter bid strategies, and ongoing optimisation that stops money going to waste.
The right keywords, the right copy, and the right structure to get your products found and bought.
Variations, inventory health, Buy Box strategy, and Brand Registry, handled properly.
Imagery and content that earns trust and turns browsers into buyers.
Weekly, monthly, and quarterly insights so you always know where you stand and where you're headed.
We also support international expansion across the UK, EU, Canada, and beyond, and help brands grow through TikTok Shop to reach new audiences.
We understand your goals and take a hard look at where your account stands today.
We build a clear roadmap that targets the changes that will make the biggest difference.
We get to work across ads, listings, and operations, making improvements that compound over time.
Once the foundations are solid, we focus on growth that lasts, not just a short-term spike.
We back everything with a simple promise. If you don't see measurable results within the first 90 days, you keep your money. No small print. We only win when you win.
Real growth. Backed by real numbers.
