Learn MORE with LESS and start Speaking 
Indonesian Today!

What if you could hold conversations with Indonesians,
in their own language, while only knowing 500 words?

- Do you often visit Indonesia or maybe you even live there?
- Is your partner of Indonesian origin and you want to talk to her/his family in their own language?
- Would you love to learn Indonesian but you're not sure where to start?
- Have you tried to learn Indonesian in the past but you still can’t hold a decent conversation?
- Want to learn Indonesian quickly and effectively?

If your answer to at least one of the above questions is ‘’yes’’, you’re in the right place!

Dear friend,

Almost ten years ago I spent some time in Indonesia as an exchange student. When I arrived I didn’t speak a word of Indonesian.

As long as I stayed close to my foreign friends I was good, but as soon as I ventured off by myself I ran into communication problems.

So I bought a phrasebook and I learned to say things like ‘’Apa kabar?’’ and ‘’Terima kasih’’.

Learning a few useful phrases made interactions with Indonesian people more fun, but I never felt that I could really connect with them without knowing their language.

So I wanted to learn Indonesian. They say that the Indonesian language is simple so learning to speak Indonesian shouldn’t be a problem, right?

- Indonesian has very little grammar
- It uses the English alphabet as
- Its word order is almost similar to English

But if Indonesian is so easy to learn, why do so few people actually become fluent?

Well, learning ANY new language can be hard

Learning to speak a new language is about programming your brain in a different way, and that isn’t always easy.

That’s why we created a system that enables you to speak Indonesian from the very beginning.

It’s all about learning to say MORE with LESS.

Did you know that it’s possible to hold simple but spontaneous and fun conversations in Indonesian while knowing only 300 to 500 words?

It all comes down to a few simple principles and if you stay with me, I’ll explain to you how it works…


Say MORE with LESS



Okay, so, I promised to tell you my big secret...

Well, if you’re familiar with our method you know that learning first things first is the key to quick progress in the beginning.

The Pareto principle (also known as the 80–20 rule) states that you get 80% of the results from 20% of the work. This principle can be applicable in language learning as well.

In language learning the ratio is more like 95-2.5, which means that native speakers only use 2.5% of the words, 95% of the time.

We call it the ''Magical 2,5%''


You see, languages contain hundreds of thousands of words but only a fraction of them are used daily by native speakers, and you only need a fraction of these words for your first conversations.

Besides that, your first conversations in a new language will always be the same.


You’ll be asked questions like;

- What’s your name?
- Where are you from?
- What do you do here?
- Do you live here?
- For how long have you been studying....?


Just learning a few answers to these questions by heart is not enough. You want to be able to construct your own sentences and speak naturally, right?

To create your first sentences you need important pronouns like: I and you; verbs like, can, do, want, be, have and a few nouns to get started.

But, just learning these important words isn’t quite enough…

At school or in traditional language courses you learn lots of words. Yet, most people can’t hold conversations in their target language after they finish their course.


Because to speak a language fluently you need to become good at two things:

1. You need to know a lot about the language. That means that you need to know many words and you need to know how the grammar works.


2. But what’s even more important, and what most people forget is that you need to know how to use these words and grammar rules in real, natural conversations.

So it’s not so much about “how much you know”, but about how well you can use what you’ve learned.

Which will help you communicate effectively with those around you and genuinely express who you are.

You see, learning a language is not just about learning a bunch of words. Your fluency is going to depend on how well and quickly you can put the words and grammar you know together.

At school we learn a lot of words and grammar. The problem is that we don’t spend enough time practicing what we have learned.

We don’t spend enough time constructing sentences that are personal to us.

Just learning is not enough, you need to activate what you learn inside your brain.


By using what you’ve learned you aren’t just less likely to forget new words, you also train your brain to quickly produce sentences in your new language. 

And that's how you will be able to speak Indonesian right away...

The Ideal Indonesian Course for Complete Beginners



But where can you find a language course that not only teaches you the most important vocabulary, but also trains you to form sentences, so that you can eventually hold conversations with native speakers?



We tested all major language learning courses but we couldn’t find anything which came close. We wanted to create something better than any other course on the market.

My friend Lucas and I spent years of our life trying to figure out what the most important words for beginners are (in Indonesian) and how to teach them in an effective way.

We wanted to create the ideal course for those who want to learn a new language from scratch. A course that focused on real results.


After more than a decade of trial and error and having learned more than 10 language ourselves, Lucas and I came to the conclusion that if we wanted a program that teaches you how to speak Indonesian from the beginning, we …


- Should teach the minimum amount of words that you can use to make the maximum amount of combinations.


- Should focus on the most important vocabulary that you’ll need for your first conversations


- The materials should come with native speaker audio and video learning tools


- The focus should be on the student; our priority is to let the student construct their own sentences!


- The program should be super user-friendly.


It wasn’t easy, but after years of testing, experimenting and seeing our students getting results we finally launched the ultimate recourse for beginners.

And we’ve called it:


VocaBooster Indonesian!

With VocaBooster Indonesian we’ve hand -picked the most important Indonesian words for you, so that you can start speaking Indonesian, right away!


But WAIT, who are you guys?

Who exactly are you guys and what do you know about learning languages?

Well, Lucas and I have dedicated the last ten years of our lives to learning foreign languages and we’ve tested all the major courses and methods.

Not only have we learned many foreign languages for fun, we’ve also lived in many different countries where we had to speak multiple languages on a daily basis. We designed this course for people who want to speak a foreign language in the real world, not just to pass an exam.

This language learning journey has brought Jan to over 100 countries and I’ve learned over 10 languages. Lucas speaks even more languages than Jan.

Over the years we’ve also interviewed many of the world's most accomplished language learners. We’ve learned what works and implemented it in our own methodology.

We also regularly speak at language events all over the world. We don’t just give these talks in English. Below you can see Lucas giving a presentation in Russian, in various cities in Russia, and even in Kyrgyzstan.


Helping people from all over the world to learn foreign languages is what makes us feel alive.

First I thought, that the example sentences wouldn't have such a big impact on the learning progress, but when I realized that I started placing adverbs and pronouns in the right position just after having studied some phrases before, I knew that was effective.

Florian Araújo



I must say that I am very happy with it! I have learned German for more than a year but mainly enriching my passive vocabulary (with Assimil and LingQ). When I will have learned the 500 words and sentences, I have the feeling I will finally feel more comfortable in speaking.

Your courses seem to be the perfect middle ground in-between saying a few cursory words, and really going for greater fluency with Glossika being my presence for that.
