Sitruna

Sitruna is a UK full-service Amazon agency that describes itself as the largest team of ex-Amazonians in the UK. Roughly 70 specialists work across advertising, marketplace operations, SEO copywriting, design and data, split between UK and Philippines-based teams, and the agency reports 200+ clients worldwide and more than £250M in managed Amazon sales.

The pitch is structural rather than tactical. Instead of hiring one overworked Amazon manager, a brand gets a built team: a client success lead owning strategy and reporting, a brand manager on day-to-day account health and flat-file work, an advertising specialist on Sponsored Ads, an SEO copywriter, and a graphic designer for A+ content, Storefronts and imagery. That composition is published openly on their site, which is unusual and makes it easy to check you are getting seniority rather than a shared inbox.

The operations side is where they lean hardest. Their stated focus is the work most agencies avoid: broken variations, duplicate listings, suppressions, compliance issues and long-running Seller Support cases, handled by people who previously worked inside Amazon. Around the core service they also run their own Sitruna App for account data and decision-making, and Sitruna Logistics, an integrated warehouse and 3PL arm for sellers who want fulfilment handled by the same partner.

Sitruna is a Nova strategic partner. Stephen Harris, who oversees strategy at Sitruna, is one of the reviewers behind Nova's Trustpilot rating. Client results and team figures above are as published by the agency and are presented as reported, not independently verified.
