Top 10 Amazon Optimization Agencies for New Sellers in 2026

Most "best Amazon agency" lists don't ask an obvious question before ranking anyone: best for who? A shop built to manage a $2M brand's ad spend and a shop built to walk a first-time seller through their first listing are not the same thing, even when both call themselves full-service. Put a brand-new seller in front of the wrong one, and the mismatch shows up fast, usually as a bill that doesn't match the attention they actually got.

That's the gap this list is built around. Every name below was picked specifically for how it treats a seller with no track record yet, not how it treats a seven-figure brand looking for its fifth agency.

What actually matters for a first-time seller

Experience helps. A big client roster helps less than people assume, because a first-time seller isn't competing for the same attention a $500K/month account gets.

A few things worth checking that most "best agency" roundups skip entirely:

1. How much risk you're taking on. A money-back guarantee or a low-commitment entry point matters more here than it would for an established brand that can absorb a bad hire.

2. Whether they'll actually explain anything. Some agencies treat a new seller like a black box client. Others treat the relationship as part-education, which tends to matter a lot in year one.

3. What "full service" actually includes. A few names below are genuinely better suited to a seller with traction already, not day-one. Worth knowing which is which before signing.

Here's the List of the Best Amazon Optimization Agencies for New Sellers

No particular order beyond the first spot. Some of these are a stronger fit for true beginners than others, and I've flagged that honestly rather than pretending every name here is equally right for day one.

1. Desverto

• Website: Desverto

• Founder: Sam Shah

• Email: hi@desverto.com

• Phone: +1 646 408 6156

• LinkedIn: Desverto

• Specialty: Amazon SEO, listing optimization, PPC, branding

• Credential: Amazon Verified creative agency

• Track record: 1,000+ brands

• Guarantee: 100% satisfaction guarantee

A new seller's first listing usually gets one real shot at making a first impression, and most agencies aimed at that stage still lead with advertising, spend more, chase the ACoS number down, before the listing itself is even solid. Desverto flips that order. As an Amazon Verified creative agency working across 1,000+ brands, the foundation gets built first: design, copy, A+ Content, the actual page a first-time buyer lands on, before ad spend gets layered on top of it. For a seller launching their first SKU, that sequencing matters more than it sounds, because ad traffic hitting a weak listing just burns budget faster.

Best for: first-time sellers who want the foundation built right before spending anything on ads.

2. My Amazon Guy

• Website: myamazonguy.com

• Founder: Steven Pope

• Phone: (470) 623-1951

• Location: Atlanta, GA

• Specialty: Full-service PPC, SEO, listing, catalog management

• Track record: 300+ clients, $1.2B+ managed

Over 2,000 free YouTube tutorials teaching the exact strategies the agency also sells as a service. That's an unusual move for a business to make, give away the knowledge, sell the execution, but it means a first-time seller can actually learn the fundamentals while working with the agency instead of trusting a black box. Worth being honest about the fit here: this agency tends to work best once a seller has some traction already, not on day one before a single sale has happened.

Best for: sellers who've launched already and want to learn the mechanics while someone else runs the account.

3. Olifant Digital

• Website: olifantdigital.com

• Founded: 2018

• Locations: New York, Los Angeles, London, Berlin

• Guarantee: 60-day money-back guarantee

• Proof: 30+ published case studies with named clients

The single best new-seller signal on this entire list. A 60-day money-back guarantee is rare in this industry, and it directly answers the question every first-time seller is quietly asking: what happens if this doesn't work out. Thirty-plus published case studies with actual named clients back it up, so it's not just a marketing promise with nothing behind it.

Best for: a seller hiring an agency for the very first time who wants the risk taken off their shoulders, not just promised away.

4. Seller Interactive

• Website: sellerinteractive.com

• Founder: Nicasio Co III

• Phone: (800) 820-3746

• Location: Markham, Ontario

• Track record: 250+ brands managed, 4.4-star verified rating

Started as actual Amazon sellers themselves between 2012 and 2014, which means the team has already made the exact mistakes a first-time seller is about to make. That firsthand history shows up in how directly they position themselves: serving new and established sellers explicitly, not just claiming to as an afterthought.

Best for: a first-time seller who wants an agency that's genuinely run a struggling Amazon account before, not just consulted on one.

5. SalesDuo

• Website: salesduo.com

• Founder: Arjun Narayan

• Location: Seattle, WA

• Team: 85% ex-Amazon employees

• Background: Founder formerly led Amazon's Vendor Management team

Founded by Amazon's own former Vendor Management Head, and roughly 85% of the team is ex-Amazon. That's a specific kind of advantage for a new seller, someone who understands Amazon's internal logic from the inside, not just from the seller-facing dashboard everyone else is staring at.

Best for: sellers who want an agency fluent in how Amazon's own teams actually think, not just how the platform looks from outside.

6. Krolog

• Website: krolog.com

• Founded: 2016

• Locations: Illinois and Toronto

• Specialty: Launch support, FBA reimbursement, account reinstatement

Beyond the standard launch services, Krolog also handles FBA reimbursement and account reinstatement, which sounds like a niche detail until it's the exact problem a new seller runs into six months in. Broad supporting services beyond Amazon itself round out the offer, useful for someone building a brand from scratch rather than optimizing one that already exists.

Best for: new sellers who want a safety net built in for the early mistakes almost everyone makes.

7. AMZ One Step

• Website: amzonestep.com

• Founders: Kamaljit Singh and Saddam Hasan

• Location: Edmonton, Alberta

• Model: Project-based or subscription plans

• Track record: 3,000+ brands since 2017

No big retainer commitment required here, project-based or subscription, which matters enormously for a first-time seller who isn't ready to sign a year-long contract before knowing if the relationship works. The creative-first approach also helps sellers who have a finished product but haven't built out visual assets yet.

Best for: a seller who wants to test the relationship before committing to anything long-term.

8. Nuanced Media

• Website: nuancedmedia.com

• Founder: Ryan Flannagan

• Location: Tucson, AZ

• Credential: Amazon Verified SPN Partner since 2010

• Recognition: Featured in BuzzFeed, CNBC, ModernRetail

Established since 2010 and explicitly includes product launch strategy as a core service, not a side offering bolted onto an existing PPC package. The independent press coverage matters here too. A first-time seller evaluating an unfamiliar agency gets some external validation before committing, rather than relying entirely on the agency's own case studies.

Best for: a new seller who wants a launch partner with an actual public track record, not just testimonials.

9. Ecommerce Intelligence

• Website: christurtonecommerce.com

• Founder: Chris Turton

• Founded: 2019

• Location: United Kingdom

• Markets served: UK, EU, US

Built by an Amazon marketing veteran specifically around a data-led launch process, the exact stage where a first-time seller has the least room for guesswork. Based in the UK but working across UK, EU, and US markets, useful if global appeal matters from day one rather than a US-only launch.

Best for: first-time sellers who want early traction driven by data instead of a generic launch checklist.

10. Sequence Commerce

• Website: sequencecommerce.com

• Founder: Alex Kung

• Phone: +1 (647) 496-5569

• Location: Toronto, Ontario

• Notable clients: Heinz, Nestlé, Duracell

A dedicated product launch service line, and a client roster, Heinz, Nestlé, Duracell, that proves the agency can execute at real scale. Worth being honest about who this actually fits. This tends to suit a better-funded first-time seller with real launch budget behind them, not a bootstrapped seller counting every dollar before the first sale.

Best for: funded first-time sellers with real launch capital, not shoestring-budget beginners.

Final Thoughts

The right agency for a first-time seller isn't necessarily the one with the biggest client list. It's the one built to handle the specific risk a beginner is carrying, whether that's budget, uncertainty, or simply not knowing what a good agency relationship should look like yet. Match the guarantee, the commitment level, and the specialty to where you actually are, not where you hope to be in a year. Did I miss an agency that deserves a spot here?

FAQs

1. What are the best Amazon optimization agencies for new sellers? Desverto, My Amazon Guy, Olifant Digital, Seller Interactive, SalesDuo, Krolog, AMZ One Step, Nuanced Media, Ecommerce Intelligence, and Sequence Commerce each fit a different stage or budget of new seller, from true beginners to funded first-time launches.

3. How do I choose an Amazon agency as a first-time seller? Look for low-risk entry points first, guarantees, no long-term contracts, transparent pricing, before comparing service lists. A first-time seller has less room to absorb a bad hire than an established brand does.

5. Is it worth hiring an agency before my first Amazon sale?It depends on the agency. Some are built for true day-one beginners, while others work better once a seller already has some traction and sales history. Check which stage the agency actually specializes in before signing.

7. What should a new seller ask an Amazon agency before signing? Ask directly whether they've worked with first-time sellers before, what happens if results don't show up, and whether the contract requires a long-term commitment. Agencies with money-back guarantees or flexible terms tend to be more honest about the actual risk involved.
