Founder-Led Amazon Growth.
Your Amazon business deserves senior strategy, not junior trial and error.
After watching traditional agencies underdeliver on high-potential brands, we built NSTAR, the profit-aligned Amazon agency we wished existed.
Brands we help grow profitably
Proven Scale by Brand Owners
Nella and Elvis run and manage your brand themselves, with 15+ years of combined experience scaling Amazon brands from $0 to 8 figures.
Built by brand owners, for brand owners. We take full accountability for your bottom line and run your brand with the same discipline we would bring to our own.
Why Brands
Switch To Us
No bloated agency playbook.
In a typical agency, the person leading the meeting is never the person managing your ads or troubleshooting Vendor/Seller Central. With us, the person you talk to is the person doing the work.
Most agencies split your advertising, catalogue, account health and content between junior account managers of uneven skill, each juggling 15+ accounts. We keep all of it with one team and one strategy.
Agency staff turnover breaks continuity and leaves you explaining your own brand to each new account manager. We don't rotate people on and off your account.
Most agencies pull levers on your Amazon brand without checking what they do to the rest of your D2C business. We make every Amazon decision with your whole business in view.
No empty promises, and no reports full of pretty graphs that never mention your contribution margin or profit.
When something needs action, we act on it the same day, weekends included. Amazon runs seven days a week, so we do too.
What We Do
Most agencies manage ROAS. We work on the numbers that decide whether your brand grows and makes money. Every channel and lever below is there to move those numbers.
The Numbers We Focus On
- New-to-brand customersShoppers buying from the brand for the first time, and what each one costs to acquire. This is how we measure growth.
- Brand profitMargin measured across the whole range. Some products take a lower margin to win customers or rank, which lifts total brand profit. We work out where that trade pays off.
- Lifetime valueWhat a customer spends with your brand over time. This sets how much we should pay to win them.
- Organic shareRank and share of search you own, so more of your brand’s revenue comes in for free.
We Run
- Sponsored AdsEach product gets a role. Some drive profit, some win new customers or rank. We set the budget to hit your brand's targets.
- Amazon DSPReaching shoppers beyond search, judged on new-to-brand potential and real incremental sales. If it doesn’t drive growth, we cut it.
- Amazon Marketing CloudCustom audiences and the customer journeys and behaviours that standard reports leave out.
- Walmart, Target & Co.Ads on other big marketplaces, run the same way we run Amazon.
- Google AdsDriving traffic to your own website, to Amazon or to other marketplaces you sell on.
We Analyse and Guide
In ecommerce, every part of the business affects the others, so we always look at the full picture of your brand.

Don’t Take Our Word for It
They are organized, focused on the metrics that matter most to us… Our brands have thrived under their watch, we’ve seen conversion rates and unit sales grow while investments on certain brands have been decreased. Elvis and Nella’s philosophy is to spend where it matters and where it will make a business impact, and they are always honest with us where additional investments will not move the needle.
