Marcin Majzner case study

Launching an online course is a balancing act. You need to get the word out fast, capture interest, and turn that interest into sales – all while keeping stress low and control high. When you’re running everything yourself, there’s no room for bottlenecks or delays.

Marcin Majzner, founder of SprzedazLive.pl and one of Poland’s leading voices in live commerce, faced this challenge. For his live shopping course launch, he needed a way to create and manage the sales page entirely on his own, with the flexibility to make changes instantly – and the speed to get it all done in a matter of hours.

Marcin Majzner educates businesses and entrepreneurs on selling through live streaming. He researches market trends and shares proven techniques for live shopping success. His training courses condense that expertise into actionable, high-value programs for a growing audience.

When You’re the Whole Marketing Team

Launching a landing page that promotes a course alone means wearing every hat – strategist, copywriter, designer, and tech support – all at once. For Marcin, the biggest challenge wasn’t just speed. It was creating a professional, conversion-ready landing page without an in-house team.

That reality came with a set of obstacles that could stall the entire launch:

  • Limited resources
  • Freelancer dependency
  • Complex processes 

As a one-person team, he had no in-house specialists to design, code, or edit landing pages. But working with outside contractors meant waiting for changes, especially after publishing, when every hour mattered.

Without the time to learn complex tools, Marcin Majzner needed an intuitive platform built for non-technical users.

The Fastest Route from Vision to Sales

For experts who want to educate their audiences, a course isn’t just another product. It’s a chance to package solid expertise into something people can act on immediately. This was the case for Marcin.

With Landingi, he built his live shopping course landing page faster than he expected and kept full control over every update – from first draft to final sale.

Fast Page Creation with a No-Code Builder

With Landingi’s drag-and-drop builder, Marcin built the entire sales page for his course in less than a day. This speed meant he could move from idea to live page without losing momentum.

Template-Driven Design

Starting from a professional template gave him a polished, trustworthy look from the first draft. Customizing it with his own content and visuals made the page uniquely his while saving hours of design time.

Full Creative Independence

Every word, image, and button on the landing page was placed there by Marcin himself. Having complete control over the page meant the launch moved on his schedule, not someone else’s.

His landing page had everything needed to win visitors over – clear descriptions that answered their questions, polished images that built trust, and a simple rundown of exactly what the course offered.

Instant Post-Publish Edits

If Marcin noticed a typo or wanted to adjust the course offer, he could jump into Landingi’s editor and update the page within minutes. Changes went live instantly, keeping the sales pitch sharp and the buying experience smooth.

From Publish to Profit

For many course creators, the sales page feels like the biggest gamble: hours of work, endless revisions, and no guarantee it will convert. Marcin knew that if he could get the right page live quickly, it could work as his best salesperson. He was right.

Marcin’s live shopping course landing page converted at 44% and sold 80 courses. The success set a new standard for all future projects. He now applies the same fast-build, conversion-focused approach to deliver results across his offers.

Yes, landing pages work. It’s the whole point of digital marketing – it simply has to work!

Starting from polished templates and refining them with his own content, he creates pages that look professional and guide visitors straight to purchase. The result is a page that works like a salesperson on autopilot.

Landingi doesn’t just make page creation easier – it gives individual entrepreneurs like Marcin the tools to launch with confidence, sell with impact, and grow without limits.
