The Girl That Forced Me to Learn Her Language FAST




In 2009 I got the opportunity to go on an exchange program in a small city in the south of China. The goal was to learn some Chinese in five months.


For some reason I’ve always been deeply interested in other countries and cultures. When I heard about the exchange program in China I was all in!


After a few weeks I got to know a nice local girl and she became my girlfriend....

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 over 15 languages. You can see is speaking all these languages on our popular YouTube channel.

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've created over 21 language courses and we've taught people from all over the world.

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.

The 3 Pillars of the
More-with-less Method

2. Sentence Building


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 these two things:


1. You need to know many words and how the grammar works.


2. The confidence and ability to make your own sentences.


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

Traditional courses mostly focus on teaching often irrelevant words and grammar. They don’t spend enough time on ‘sentence building’.


Studying alone is not enough; you need to activate what you learn inside your brain.


By directly using the words you learn, you aren’t just less likely to forget them; you also train your brain to produce sentences in your new language quickly.

3. Fluency Training


Becoming fluent in a new language takes a lot of effort and it isn’t easy as most programs claim.

The only way to become fluent is to create strong connections in your brain so that you don’t need to translate in your head anymore. Instead you can speak in a natural way.

This process usually takes years but a ‘spaced repetition’ system like Anki will help you speed up the process in just 10 to 20 minutes per day.

I’ve known Jan and Lucas for a few years and I’ve always found their language learning ideas and tips extremely useful. I was so impressed by Lucas’ story that I even mentioned him in my TED talk as a very inspiring polyglot. The talk has been watched by over 4.5 million people. 

We’ve had dozens of hours of conversation about language learning, so I know that these guys know their stuff about language learning, especially when someone is just starting. 


Highly recommended!

I have tested most language applications, books and courses out there and I can honestly say that language boost uses one of the best methods. It gets you from A-B very quickly and cuts out a lot of the useless rubbish a traditional language school might teach you. 

If you are a real stickler for detail and grammar etc. it could be a bit light, but if you are just looking to pick up and start using the language quickly, I can highly recommend these guys!

Jan and Lucas have more experience learning foreign languages than almost anyone on the planet. 

If you want to learn to speak a new language and learn quickly, I recommend you pay attention to what these guys have to say!

Why Learning Experts Love this Approach so Much



We’ve used this methodology to reach high levels in a dozen languages ourselves, but even more importantly, we’ve also witnessed how well it works for complete beginners.

The world’s most famous learning experts can explain why this method works so well.

Let’s take a look at what they say...

An interview with Scott that I did a while ago for our podcast.

Benny wrote an article for Tim Ferris titled: 12 Rules for Learning Foreign Languages in Record Time. His number one rule:

Learn the right words, the right way!

He said:


‘’As Tim (Ferris) pointed out in his own post on learning any language in 3 months, you can take advantage of the Pareto principle here, and realize that 20% of the effort you spend on acquiring new vocab could ultimately give you 80% comprehension in a language.”

Me visiting Benny in Valencia, he was kind enough to host me in his apartment  for a few days.

Also, popular YouTuber Arieh Smith, aka Xiaoma, uses a similar method on his crazy language learning missions. He usually spends 24 hours learning a new language and then goes off to a New York neighborhood where that language is spoken to have conversations with native speakers. 


His secret? 

He says;

''I usually create a list of words and simple sentences that I can immediately start using with people in the street. Think about simple phrases like:

  • Do you speak Korean?
  • I am learning Korean
  • I want to go to the market
  • How much is this?
  • It’s tasty!

These are things that I know I need to say if I want to have a basic conversation with random people in the street or in restaurants, so that’s what I focus on.


Then I ask a friend or a tutor to translate the phrases and even record the audio. I put them into a flashcard app called Anki and I use that app to learn the phrases by heart''

“I recommend this boostcamp to all my friends. It’s such a different way of learning a language compared to the way we learn languages at school. You get to speak the language right from the beginning.”

''I just took a look at the first lesson for the Boostcamp and it's fantastic. I was surprised how quickly it really drilled those first 20 words into my brain''

I would say that this is probably the best way to start learning a foreign language. I know what I mean here because I have a degree in linguistics and education and I have been working with languages professionally for eighteen years.


This course gives you an unbelievable feeling of achievement and helps you to create a natural connection with the language.

Mila Khabirova


I have researched and tried at least a dozen different language learning tools, software and approaches.


This Jumpstart thing is the only approach that I found that had me speaking, conversing, and understanding what I said on day one!

I love your courses! I finished ALL your Boostcamps and went on Italki to test my progress and had 30-minute conversations! 

Rommel San Pedro

Learning new vocabulary in sentences is awesome. All the promises you make in your sales material is true in this respect. I also appreciate that you emphasize verbs much more than I’ve seen in other systems. That adds to the sense of usability. All this has increased my motivation because I can see progress where I previously struggled.


In a nutshell your program is the best I’ve used for studying Russian, trust me I’ve tried most everything.

Mike Whispers

Hi Jan, the new lessons in Jumostart are excellent. Your method is by far the best system for learning a language for me.


The Jumpstart series is right on the money! Thank you for the method and for inspiring me to try learn a new language. I find it fun and rewarding. Cheers!

Darrell Wong 


I don't know why anyone that is interested in language learning would not take advantage of this opportunity.


The price right, the process is right, and the customer service and support is exemplary!
