About Ekaterina Rubtcova

Ekaterina Rubtcova — founder of the Daniks cookware brand and Daniks.AI

Personal blog · Ekaterina Rubtcova

I'm Ekaterina — an Amazon seller who writes about what actually works.

Selling on Amazon since 2018. Founder of the Daniks cookware brand. Founder of Daniks.AI, the AI-native PPC automation I built for my own listings.

The short version

Before Amazon, I spent years inside some of the world's largest IT companies. In 2018, I launched my first private-label product on Amazon and never looked back. That product became the Daniks Stainless Steel Induction Cookware Set under my Daniks brand — Top-1 in Germany, now Top-20 in the USA. You can look it up; it's a public listing.

Running that brand at scale, I got tired of PPC tools that pretended AI meant "rules plus a dashboard." So I built my own — Daniks.AI, founded the same year, 2018. An AI-native Amazon PPC automation that manages bids against a target ACoS with an actual agent, not a rules engine. I built it for my listings first. It worked. Hundreds of Amazon brands run on it now.

I work in three languages — English, Russian, and German. It is how Daniks reached Top-1 in Germany before we scaled into the US, and it is why I can tell you what a launch actually looks like across two marketplaces instead of just one.

This blog — and the @AmazonFBAGirl YouTube channel — is where I share the operator-level reasoning behind what I actually do. No courses. No coaching. Nothing to upsell.

Why you can trust what you read here

  • Real seller with a public Top-ranked product. My flagship is Daniks Stainless Steel Induction Cookware Set — reached Top-1 in Germany, currently Top-20 in the USA. You can verify the listing, the reviews, and the ranking yourself.
  • Real name, real LinkedIn. I don't hide behind an alias — here's my LinkedIn profile. Connect with me.
  • Seller-built software, proven on my own account. I founded Daniks.AI as a seller who needed the tool — not as a software founder looking for a market. It's running on my Daniks ads right now, and on hundreds of other Amazon brands.
  • IT background before Amazon. I worked at some of the world's largest IT companies before 2018. That's where the engineering instinct behind Daniks.AI comes from — and why the blog leans toward systems, numbers, and root causes instead of motivation.
  • Nothing to upsell you. No course. No coaching program. No mastermind. The blog and the YouTube channel are free, and that's the whole offer.

What you'll find here

Honest, operator-level writing on Amazon selling — product research, PPC, listings, brand building, policy changes — framed the way I'd explain them to another seller over coffee. If something didn't work for me, I say so. If I don't know the answer, I say so.

  • Blog posts — long-form breakdowns of what's actually working on Amazon right now
  • Tutorials — step-by-step walkthroughs of the workflows I use myself
  • Tool reviews — candid takes on the software sellers pay for
  • News — Amazon policy changes and marketplace shifts, translated into seller English
  • Lifehacks — small efficiencies that add up over a year of selling

Come watch — YouTube is where it's best

The blog is the reference library. YouTube is where you should actually meet me. That's where I record screens, walk through live listings, and answer seller questions in real time.
