Arek and Brian Zabierek, better known as The Zab Twins, are quietly rewriting what it means to build real wealth on Amazon. As founders of The FBA Start-Up, they’ve helped over 500 students go beyond “side hustle” mentality and launch full-fledged eCommerce businesses grounded in systems, strategy, and results. Arek is the precision-driven architect behind the backend infrastructure, while Brian is the creative force shaping brands that actually connect and convert. Together, they’re not just teaching Amazon FBA; they’re building a next-gen movement for digital entrepreneurs ready to take ownership of their time, income, and future. In this interview with TechBullion, the twins unpack what it’s really like to build a business together, the systems behind their students’ success, and how they’re helping a new generation win in what they call Amazon 4.0.
Please tell us more about yourselves and what you do at The FBA Start-Up?
Arek: Hey, I’m Arek Zabierek – one half of The Zab Twins. I run the strategy and systems at The FBA Start-Up. Everything from tracking student progress to scaling our own Amazon brands runs through the backend I’ve built. I’m obsessed with making data work harder so our students don’t have to.
Brian: I’m Brian Zabierek – co-founder and the creative engine at The FBA Start-Up. I’m the guy behind branding, product positioning, and making sure our students aren’t just “on Amazon”—they’re winning on Amazon. I lead trainings, break down product strategy, and help people build real businesses, not side hustle fluff.
You’ve helped over 500 students launch their own Amazon businesses, what systems or frameworks do you rely on to keep that level of scale high-impact and hands-on?
Arek: We built a real system – not just a course. Everything runs on what we call the Path to $10K: 10 steps that guide someone from product research to profit. It’s tracked through custom automations and milestones inside our CRM. Plus, we’ve got a support team in place to make sure no one slips through the cracks.
Brian: From the student side, it’s as simple as we don’t ghost our people. We blend group coaching, private mentorship, and updated trainings so students are never left guessing. Everything’s designed to push people toward action, fast. That’s why our results speak louder than most other gurus’ promises.
What does running a business as twin brothers really look like day to day? Who does what, and how do you navigate decision-making when you don’t agree?
Arek: We’ve been building stuff together since we were kids. I handle the backend: systems, supplier ops, product margins. If there’s a spreadsheet involved, it’s mine. When we disagree, we let the data decide.
Brian: I lead creative – brand angles, offers, and marketing. And yeah, we don’t always agree. But we’ve got a rule: no ego. Just what’s best for the business and our students. We challenge each other constantly but honestly, that’s how we grow.
You emphasize building freedom ‘one product at a time.’ What’s your exact method for choosing a product that’s worth your time, energy, and capital in 2025?
Brian: 2025’s not about trendy – it’s about timeless. I look for demand-backed products that solve real problems, then figure out how we can position and differentiate it better than anyone else. That’s where we win.
Arek: Once we have the idea, I run it through our Winning Product Formula – margin checks, supplier availability, future potential. We don’t launch unless it can scale.
What’s one product launch or strategy that flopped, and what lesson did it teach you that you still apply today?
Brian: Early on, we launched something that looked great on paper—but had no real way to stand out. Let’s be real… it bombed. Now, I always ask: Who’s buying this? Why would they care? How does it actually solve a problem and separate from the competition? If the answers aren’t immediate, we don’t launch.
Arek: We once rushed a supplier and skipped proper sampling. Looked fine until we realized the size was off and shipping costs shot way up. It crushed our margins and wasted a ton of time. Lesson learned: speed is good, but not if it sacrifices precision. Vet everyone. Always.
How do you balance growing your own Amazon brands while actively mentoring a fast-growing community of new sellers?
Arek: I structure my weeks tight. I’ve built a team around me so I can stay focused on high-leverage stuff, like optimizing systems and supporting our coaching ops. If it doesn’t move students or our brand forward, it gets cut.
Brian: I stay close to the students. I run weekly calls, I check in on product launches, and I still test new ideas on our own Amazon accounts. That way, everything I teach is real-time, not recycled.
You’ve built a no-fluff alternative to traditional learning. What do you believe schools miss when it comes to teaching young people how to actually earn online?
Arek: Schools teach theory. We teach action. Nobody needs another textbook or a lecture. They need steps, tools, and accountability. That’s what we built.
Brian: They also don’t teach ownership. Our whole program is built around helping people own their time, income, and life. That’s what young people actually want – and need – in 2025.
What’s one Amazon FBA trend in 2025 that most people are overhyping, and what’s one underrated opportunity you think more sellers should jump on now?
Brian: Overhyped: AI listings. Everyone’s using them, and most of them sound the same. If you’re not prompting it right or adding your own twist, you’ll blend in and get ignored.
Arek: Underrated: supplier strategy. Most sellers think it ends at Alibaba. It doesn’t. Long-term brand deals, MOQs, and quality terms – that’s where real sellers win.
What makes The FBA Start-Up ecosystem different, and how are you thinking about expanding that community in 2025 and beyond?
Arek: We’re not selling courses. We’re building results. Our ecosystem is designed like a business incubator. In 2025, we’re layering in even more automation, data tracking, and performance-based coaching. It’s going to feel less like a course and more like having a team.
Brian: We evolve with what’s working fast. We test stuff in our own brands, and our students get the updates first. Whether it’s Amazon Ads, Canva integrations, or AI tools, they stay ahead because we stay ahead.
With AI, automation, and Amazon’s own evolution, how are you approaching what you call “Amazon 4.0”, and what role will The Zab Twins play in shaping that future?
Arek: Amazon 4.0 is smart systems meet smart sellers. We’re building behind-the-scenes tools to automate the grunt work so our students can focus on what actually drives profit. Less guesswork, more growth.
Brian: Our role? Pushing the edge. We’re already partnering with tools like Amazon Ads, Jungle Scout, Alibaba and Helium 10. We’ll keep showing everyday people how to plug in, compete like pros, and own their outcomes.
