In a world where e-commerce giants dominate and competition is relentless, building a business on Amazon is no walk in the park. But Alex Karagiannis, founder of Lezzat, an Amazon service agency, turned a £500 investment into a thriving business—by leaning into change, embracing uncertainty, and reinvesting every step of the way.

From Athens to Aberystwyth: A Global Perspective

Alex’s story starts in Athens, Greece—a city steeped in tradition. But his future would be anything but conventional. After finishing his A-levels, Alex moved to the small Welsh town of Aberystwyth to study business management and international marketing. The cultural shift was stark, but it gave Alex a fresh perspective and the academic foundation for what was coming next.

Navigating Uncertainty with Resilience

The 2008 financial crisis made job-hunting in Greece tough, especially for recent grads. But instead of staying stuck, Alex looked abroad, joining a graduate program in the UK tech industry. This early experience in B2B marketing and outsourcing gave him critical insight into how businesses operate—and sparked his entrepreneurial spirit.

But it wasn’t a straight shot to success. A serious car accident, career uncertainty, and personal setbacks forced Alex to pivot. He worked part-time in a café, all while exploring new paths. That’s when Amazon entered the picture.

Crashing Into E-commerce

Alex and a few friends pooled £500 each to start selling on Amazon. It was messy—wrong product colors, supplier miscommunications, late-night calls to China—but every misstep became a learning opportunity. He took online courses, analyzed listings, and adjusted quickly. What started as a side hustle began to snowball.

Lezzat Is Born: Niching Down for Impact

In the early days, Alex’s agency tried to be everything to everyone—offering general marketing services to a broad range of clients. But the turning point came during a conference in Greece, where a chat with another agency owner helped Alex see the power of specialization. He doubled down on Amazon services—product listings, advertising, photography, and more.

That clarity changed everything. Lezzat became a strategic partner for e-commerce brands looking to scale on Amazon. The agency now helps clients navigate listing optimization, ad campaigns, and international expansion—all informed by Alex’s firsthand seller experience.

Why Reinvesting (and Not Taking a Salary) Matters

A major theme in Alex’s story? Playing the long game.

In the first three years, Alex and his partners didn’t take a salary. Every penny was reinvested into inventory, operations, and learning. Revenue grew from £22,000 in year one to £200,000 by year three—without external funding.

The takeaway? Forget the overnight success narrative. Building a real business requires sacrifice, discipline, and patience.

Service vs. Product: Two Sides of the E-commerce Coin

Through his journey, Alex’s seen both product and service businesses up close. Selling products on Amazon is fast-paced and transactional—you deal with stock, logistics, and the occasional refund. Running an agency, though? It’s all about relationships, expectations, and consistent service delivery.

Service businesses scale differently. You don’t just sell more; you build a team, manage people, and systemize results. Both models have unique challenges, but understanding the differences helped Alex build smarter.

Leveraging AI to Stay Ahead

As e-commerce evolves, so do the tools that drive it. Alex is a firm believer in using AI for listing optimization, market analysis, and customer experience. Whether it’s chatbots for instant responses or data tools for ad strategy, technology is key to staying competitive.

For sellers just starting out, Alex recommends using free AI tools and watching tutorials on YouTube. In a landscape that never stops moving, staying curious is a superpower.

Customer Obsession = Business Success

One of the biggest lessons Alex shares is to think like your customer. Why would they buy your product? What are their pain points? What are competitors doing better?

Whether it’s pricing, reviews, or features, obsessing over your customer’s experience helps you improve faster than the competition. And when you act on that insight, you’re no longer guessing—you’re solving real problems.

Final Thoughts: What You Can Learn from Alex

• Start now – There’s never a perfect time to launch. Amazon is still wide      open for smart sellers.
• Pick a niche – Focus wins. Generalist agencies get lost. Specialists      thrive.
• Reinvest – Short-term sacrifice = long-term growth.
• Use tech – AI isn’t optional anymore.
• Know your customer – Your growth depends on their satisfaction.

Alex’s journey is proof that you don’t need a perfect plan—you just need persistence, curiosity, and the guts to get started.
