Teaching 10,000+ Students Online Marketing

Hi my Name is Daniel!

I´m a passionate Entrepreneur, Digital Marketer and Online Coach with hundreds of happy students.

At the Age of 18 I founded my first business - an "offline" Marketing Agency where we promote product from big brands in shopping malls and on events ...

But after 1 year I realised that the "internet world" offers a much bigger opportunity for building a business ...

In Late 2014 I launched the first regional Online Job Exchange for students - this platform was quite sucessful, but not very profitable. 

In 2015 established my first Digital Marketing Agency , where my team & I help clients to get more Leads and Sales over the Internet.

During this "agency years" my co-founder and I always wanted to create our own product - so after a few tries we started to build ventures in the Ecommerce sector and currently work on our SaaS Business for Onlinebusinesses.

In my courses I want to share my knowledge and my experience from my different ventures and client projects :)

Best Regards,

Teaching 140,000+ Students, Performance Marketer

Hi, I'm Sandor!

I am passionate entrepreneur and performance marketer with ten thousands happy students.

Let me tell you my story...

At the age of 16, I founded my first online business. After being a full-time CPA marketer for more than 5 years, I decided to shift gears and use my skills to build companies.

Ever since, I have been lucky enough to do what I love the most: entrepreneurship, travelling the world, pushing my comfort zone and discovering things that I couldn't learn in the classroom.

One year ago, I decided to take the next step and share my knowledge with those who are ready to start their own business. This decision brought me to Udemy, where I am able to combine my biggest talents: entrepreneurship, marketing and teaching.

My teaching philosophy on Udemy is simple: I am crafting trainings that I wish I had available to me when I started my first company.

My courses serve a very important goal: helping you to transform your life and becoming a successful entrepreneur and marketer.

I've seen the impact a solid business can have on someone's life. That's why I can only encourage you not to miss out on this opportunity.

As of today, I've sold more than 250,000 trainings, established multiple successful online businesses and coached hundreds of students.

So, that's my story. But now, I just want to ask you a simple question.

Do you want some help?

Do you want to establish your own business, become an entrepreneur or simply generate more revenue from your current business?

Great, because I am sure I am going to be able to help you. Feel free to check out my course portfolio and let's see if we can work together.

Best Regards,

Sandor Kiss
