The 7 best Amazon agencies for tech and health-tech brands
1. Olifant Digital
Olifant Digital is a full-service Amazon and e-commerce marketing agency for established brands that want profitable growth. For tech and health-tech brands, one experienced team runs strategy, daily PPC, Amazon DSP, listings and creative, catalog and account health, and profit tracking per SKU, with our in-house AI platform, Olifant AI, checking every campaign daily. We manage $100M+ in annual client revenue across 50+ brands.
The tech and health-tech brands we work with show what that looks like in practice:
- AYO, a light-therapy wearable, entered an emerging category with no demand and no sales history. We built the demand and scaled it on Amazon from $0 to $70,198 a month as a category leader (case study). Its Amazon sales grew 66% from January to September 2026 against the same months of 2025.
- Inito, an 8-figure fertility tech brand, has been with us since August 2026. Its year-over-year growth went from 82% to 114%, and Sponsored Products ACoS went from 17.4% to 15.1%.
- Ultrahuman: we have managed its Amazon.de account.
- Ekster, a smart wallet and tech accessory brand, added $688,406 in annual Amazon profit after we rebuilt the channel (case study).
- Typical client: established tech, wearable and health-tech brands on Seller Central or Vendor Central
- Services: Amazon account management, PPC, Amazon DSP, listing optimization, A+ Content and creative, catalog and international expansion
- Results: AYO $0 to $70,198 a month; Inito growth from 82% to 114% year over year; Ekster +$688,406 annual profit
- Fees: services start from $2,000 per month on a month-to-month retainer, with a 60-day money-back guarantee on management fees
- Worth knowing: #1 on Clutch's Top Amazon Marketing & Advertising Agencies list with a 5.0 rating; 98% client retention
The honest limit: the $2,000 starting fee is built for brands with traction. A new seller with one product and a small ad budget will usually get more from software or a freelancer first.
2. Sequence Commerce
Sequence Commerce is an Amazon advertising and AI search optimization agency for e-commerce brands. Its site lists Amazon management across 16 marketplaces, including DSP, Amazon Marketing Cloud and Vine, next to Walmart, Target Plus, Instacart, Wayfair, Shopify Plus, TikTok Shop and Meta.

- Services: Amazon ads, AI search optimization (AEO and GEO), marketplace media, cross-border expansion

3. Buy Box Experts
Buy Box Experts is an Amazon agency for marketing and account management. Work starts with its Total Amazon Business Audit, which reviews keyword ranking, listings, advertising, category trends, market share, competitors and off-Amazon channels.
- Typical client: brands that want a full audit before choosing a service
- Services: account management, Amazon advertising, Amazon SEO, conversion rate optimization, international expansion
- Standout: a structured audit with a presentation of findings before work begins
- Worth checking: which services sit inside the monthly scope and which are priced separately
4. Marketplace Valet

- Services: account management, listings, brand content, Amazon Ads, DSP, Amazon Marketing Cloud

What we see in tech and health-tech accounts
These patterns come from our September 2026 data across 66 Amazon ad accounts, plus the tech brands we manage.
- Top of search wins the comparison buyer. Top-of-search clicks converted at 13.1% at a 26% ACoS, against 5.5% at a 39% ACoS on product pages. Tech shoppers compare specs, so being the first result matters.
- Health clicks cost more and convert well. Supplement and health accounts ran a median 24% ACoS with a 12.0% conversion rate, at a $2.27 CPC.
- Sponsored Display finds new buyers. 78% of Sponsored Display sales came from shoppers new to the brand, at a 21% median ACoS. That suits brands with accessories, refills and add-ons.
- Waste stays small when it is cut early. Search terms with 10 or more clicks and no sale took about 5% of spend, because daily checks and our Kill Threshold Rule pause a keyword when it has zero sales after 14 days and has spent twice what a single sale earns before ad costs.
- Efficiency can improve while growth speeds up. At Inito, Sponsored Products ACoS went from 17.4% to 15.1% as year-over-year growth went from 82% to 114%.
How to choose an Amazon agency for a tech or health-tech brand
Does the agency know device rules as well as ad rules?
Health-tech devices carry risks that most consumer products do not. Amazon's restricted products rules cover medical devices, and some products need documents before they can be listed. A wellness wearable that drifts into disease claims in a title, bullet or image can be suppressed, so copy has to stay on what the product measures or supports.
Connected devices add a second layer. Products with lithium batteries go through Amazon's dangerous goods review before they can be stored in FBA, and a missing safety data sheet can hold inventory for weeks. Supplements have their own claim limits, covered in our guide on how to sell supplements on Amazon.
Reviews follow the same logic. Amazon Vine is Amazon's own compliant route to early reviews. An agency that offers incentivized reviews or search-find-buy schemes is telling you how it treats every other rule.
Can it tell you break-even ACoS for your top products?
ACoS is ad spend divided by ad sales. Break-even ACoS is the point where an ad pays for itself, and it equals your contribution margin. A product that sells for $50 with a $20 contribution margin has a 40% margin, so its break-even ACoS is 40%. Any campaign above that buys revenue at a loss.
An agency that cannot give you this number for your top ten SKUs is managing spend, not margin. Run the math yourself with our Amazon ACoS calculator.
Can creative keep up with your launch calendar?
Tech product cycles are short. Every launch needs new images, video, A+ Content and comparison charts, and every competitor price move changes what wins the click. When creative and bids fall behind, share slips while the reports still look healthy.
Who works on the account?
Junior staff learning on your budget is the most common way agencies lose trust, and it rarely shows in the first quarter. Senior account managers cost more and waste less, which usually makes them the cheaper option by the end of the year.
Questions to settle on the first call:
- Who works on my account, and how many other accounts does each account manager carry?
- How do you measure profit: break-even ACoS and contribution margin, or revenue alone?
- How do you handle claim rules, restricted product documents and battery reviews?
- What happens if results miss, and is that in writing?
- What is the fee model, and does it include a percentage of ad spend?
What does an Amazon agency for tech brands cost?
Amazon agencies usually charge a monthly retainer, a percentage of ad spend, or a mix of both. Retainers keep the agency's income separate from how much you spend; percentage models grow the fee as the budget grows. At Olifant Digital, services start from $2,000 per month on a month-to-month retainer. For a full breakdown, see how much Amazon agency management costs.
Frequently asked questions
How much does an Amazon agency for tech brands cost?
Most agencies charge a monthly retainer, a percentage of ad spend, or a hybrid. At Olifant Digital, services start from $2,000 per month on a month-to-month retainer, with a 60-day money-back guarantee on management fees.
How long does it take to see results from a new Amazon agency?
The first 30 days usually go on audit, catalog cleanup and rebuilding campaign structure, and performance can hold flat while waste comes out. Profit usually starts moving in month two, and a full picture takes a quarter, because organic rank responds more slowly than ads.
Should a tech brand run Amazon DSP?
DSP helps tech brands reach shoppers who viewed their products or competing products, and Amazon Marketing Cloud shows how DSP and search ads work together. We run DSP as a premium service and prove its real impact with holdout tests before scaling the budget.
Do health-tech devices need approval to sell on Amazon?
Some do. Amazon's restricted products rules cover medical devices, and certain products need documents before they go live. Wellness devices should avoid disease claims in titles, bullets and images.
Do we need separate agencies for Amazon and our own website?
One team covering both usually works better, as long as it understands marketplace mechanics. Split ownership creates pricing conflicts, mismatched creative and arguments over which channel gets credit for a sale.
What are the warning signs that it is time to change Amazon agencies?
Reports that lead with impressions and revenue and never reach contribution margin, account managers who rotate every few months, and campaign structures nobody has touched in half a year. A straight answer about who works on your account and what changed last week should take one message.
Final thoughts
Every agency on this list can run an Amazon account. Tech brands need a partner that keeps creative and bids moving at the speed of their launches, and health-tech brands need one that writes compliant claims that still sell. Olifant Digital ranks first because it does both under one experienced team and reports to profit per product, with results like AYO's $70,198 a month.
