I’m happy to announce that I invested in Busuu, the most active language learning community worldwide. Busuu already has over 2 million users and is growing rapidly, adding more than 10,000 new users each day. Busuu also overtook its two older and more heavily funded main competitors, as this chart shows.
How does Busuu work? In addition to providing the resources to enable individual language learning, users can interact with each other and engage in what Busuu calls “community learning”. Take me for example. Despite having a German wife, I still use Busuu to learn German. With the community feature, I can submit text exercises I wrote to be corrected by other users who are German native speakers. Sometimes I also use the instant video chat to practice speaking German (although I admit that I still have a far way to go :)). Being a native Spanish speaker, I could now help other users who are learning Spanish by correcting their exercises or talking to them directly. Those who are looking for an entertaining way to learn a foreign language may look into language learning with netflix. You may also take Foreign Language Courses to help you learn languages more effectively.
The language learning market is huge – about $90 billion worldwide with around 1 billion people alone learning English. Busuu’s monthly revenue is a 6-digit figure and the company is already reporting positive cash flows. In addition to the 7 languages currently offered, Busuu is planning to add at least 4 more this year, including Mandarin and Japanese. They also launched several pilot projects with schools, universities and companies to enter the institutional market. And of course I should also mention the very popular Busuu iPhone app.
The CEO, Bernhard Niesner is a former student of mine at IE. He is Austrian, the company is based in Madrid. It’s amazing what this great team has been able to accomplish so far on their relatively small initial investment. Keeping up this capital efficiency and growth I see Busuu keeping its leadership in the enormous global language learning market. Busuu is the kind of investment I like because it fits my three key criteria for angel investing: a product I love, an entrepreneur I admire and a company I can help grow.
Here are some pictures of Johann, Adrian, Bernhard and me that Nina took at the signing:

I got a patent for the invention of Fon in USA
Published by MartinVarsavsky.net in Fon with No Comments
This has been a very good week for Fon. I’m very excited to announce that my lawyer Douglas from Ostrolenk Faber sent me an e-mail telling me that an important patent we filed in 2006, issued on Tuesday.
Simplifying all the legal details, the patent basically boils down to this: it protects the core business model of Fon in the US.
As most of you already know, with Fon “you share WiFi at home and you roam the world for free connecting to like-minded people”. For those of you unfamiliar with our business model, here’s how it works: one user, the Fonero, connects a Fonera WiFi router to his DSL/Cable/Fiber internet source or modem. Thereby he creates a Fon hotspot. If a Fonero wants to connect to another Fonero’s hotspot, he can do so for free in any of our 3.7 million hotspots of the largest and fastest growing WiFi network in the world. If a non-Fonero (at Fon we call this person an “Alien”) is in range of the Fonero’s hotspot and wants to connect to the internet with any WiFi device, he can do so for a moderate access fee.
The good thing about our technology is that it is not tied to the Foneras. Our software can transform almost any standard WiFi router into a Fonera! This makes it easy for most ISPs (like BT) to convert their routers into Foneras and make the Fon community even larger.
What’s special about this patent is that it relies on the community aspect of Fon. It specifically requires at least two users to share their bandwidth through two separate WiFi routers, which seems pretty obvious but is important when it comes down to the legal aspect. This is also what sets Fon apart from other WiFi networks that work without Foneros and offer only paid access to the internet.
In summary, this patent is very good news for us and will give our future business partners in the US even more reasons/confidence to work with us, accelerating our growth. It is also good news for people in the US since the availability of WiFi hotspots will increase dramatically during the next few years. And, of course, this patent means good news for all existing Foneros, who will soon be able to roam more and more parts of the US for free!

What is Judaism?

While going around the Jewish Ghetto in Berlin I make a video directed to non Jews in which I explain what I think Judaism both from the point of view of Jews and those who hate us. In doing this I get into a topic that is well explained in Wikipedia, that of secular Jewish culture.
And here are some pictures I took in Berlin

A more optimistic view of Fukushima
Published by MartinVarsavsky.net in International with No Comments
Unlike most, I don’t think that the worst is yet to come in Japan. Based on what I have read, I believe that what we have seen so far is likely going to be most, or all, the damage there is going to come out of the earthquake/tsunami/nuclear accident combination. And that is a already a lot. With maybe 15K people dead, half a million homeless, $200bn in damage, I don’t understand why the media focuses so much on a potential major nuclear accident with casualties in Tokyo, something that I can’t see how it would happen. There’s enough non nuclear tragedy to focus on and to help with right now than to make people panic over a highly unlikely event.
I am an entrepreneur, and a big part of my life is assessing risk. After obsessing with the Japanese problem (I have dear Japanese friends, Fon has employees in Japan, and Japan is our second most important market at Fon) my own impression is that we have a 20% chance of Fukushima being a Chernobyl. A significant but not overwhelmingly high chance. And even if the worst happens and it is a Chernobyl, because Fukushima faces the ocean, the prevailing winds are westerly and it is surrounded by mountains, I just can’t see how Tokyo (or any major city) would be affected by the nuclear accident. In the case of Chernobyl, Kiev, a major city that is half the distance to the accident than Fukushima is to Tokyo, was not affected. Kiev went on with its life after Chernobyl.
And then there is the anti nuclear panic that we are seeing these days. People around the world are very concerned about nuclear power and I can understand the psychology of this. People fear what they fear, not what is more likely to kill them. People fear planes more than cars, and flying is safer than driving. Coconuts kill more people every year than sharks, and I don’t see people reacting to coconuts as they react to sharks. Going back to nuclear, it is hard to argue that Fukushima is representative of the nuclear power plants of today. The Fukushima nuclear plant was built in the 60s. It is so old that it should have been decommissioned last month and somehow it got an extension to operate. The regulators who approved this are probably feeling horrible right now. But if there’s anything Fukushima should teach us, it should be not to avoid nuclear energy, but to be more careful with nuclear, to understand the risks. Nuclear energy is dangerous, but it is clearly not as dangerous as driving a car for example, and nobody is advocating an end to the car industry. We drive because we love the convenience and we try to minimize risks, and the same should be true of the nuclear industry. Nuclear energy is cheap and climate neutral. But it is risky, and to build nuclear plants in seismic faults, as it is done for example in Japan and California, is a questionable practice. Fukushima shows us that all our precautions were not enough. What I hope that comes out of this nuclear accident is: no major radiation leaks a la Chernobyl (i.e. that the 20% does NOT happen), a reassessment of the industry practices and safer plant design. I also hope that this leads to more investment in solar and wind, alternatives that while not as efficient are certainly safer and simple. And of course more energy conservation in general. In the meantime my heart is with those heroes who are fighting the nuclear accident right now at the risk of their own lives.
Lastly I would like to say that I know that this article may come back and haunt me if in the next hours we do have a major escalation of events in Fukushima and Tokyo has to be evacuated. But I am not saying here that is impossible that this happens. I just think that at a time in which media goes on and on about how dangerous the situation is, I felt I had to argue why they may be exaggerating.
Even though there is a civil war going on in Libya and global powers are divided on a course of action, there seems to be remarkable agreement that whatever is going on in Libya is, for everyone who has something to say about it, “unacceptable”.
–Obama calls the bloodshed in Libya unacceptable.
-at the same time Gaddafi calls the Arab League support for a no fly zone unacceptable.
-and the Russians are calling outside meddling in Libya unacceptable.
–David Cameron has called Gaddafi’s regime unacceptable.
-Lastly, possible GOP presidential rival of Haley Barbour called the price of gasoline resulting from the Libya conflict unacceptable.
Now my question is, if what’s going on in Libya is so unacceptable to everybody. Why is it still going on?
Added a day later, Iran gets into the game calling foreign soldier intervention in Bahrain “unacceptable”
Fon’s WiFi network is by far the largest in Japan with over a million hotspots of which over half a million are on at any one time. Normally the Fon network is free to those who share WiFi (known as Foneros) and other users pay. Given the current emergency in Japan, and the failure of some mobile networks as a result of the earthquake, Fon has decided to open our network to all of those in Japan. The software changes required are being worked on at our headquarters in Madrid and will be ready in an estimated 3 hours or around 6pm Spanish time. Japan is 7 hours ahead of us so it will be around 1am in Japan when all our hotspots are open to the general public. We hope those stranded or in need find the Fon network useful. We also encourage owners of Fon WiFi routers who may not have their Fon WiFi routers (Foneras) connected to connect them to help anyone who may need connectivity. All this is being done in collaboration with our friends at Softbank who currently distribute Foneras in Japan. We would like to send our condolences to the families of those who died in this sad tragedy and wish all in Japan a quick recovery from this natural disaster.
Update: Work done in Madrid, the Fon WiFi network in Japan is now open for all to use until the emergency is over. I would like to thank our colleagues at Softbank, our engineers in Spain and above all the Japanese foneros who make this possible.

Second Stream of Tweetphorisms
Published by MartinVarsavsky.net in General with No Comments
A few months ago I published a list of what I call tweetphorisms (tweets + aphorisms). Here’s the second round! You can also check out my spanish list here.
- I started Fon because I wanted WiFi everywhere. I recommend that your next start up solves a problem that is dear to you.
- The Stop sign system is a waste of energy. They should replace Stop signs for Yield signs.
- Twitter should allow you to hyperlink, it would look better and save characters.
- Small victory in the world of the intercontinental traveler, an empty seat next to me.

- As a father of four I can tell you that there is nothing genetic about sharing. The younger, the more selfish 🙂
- Fashion can be interesting but expensive clothes rarely are
- Having oil makes countries dumb
- It is absurd to speak about gender equality, genders are by nature different. Feminist objective should be “equal pay for equal work.”
- Twitter is like a classroom, of all the people you follow there are always a few who raising their hands all the time
- Frequently people ask me to invest but even more frequently they ask me if I have key managers to recommend. People are more important than money
- I know people who never update their software and somehow, they seem very happy
- Religion is a proof that absurdity is more comforting than ignorance.
- Unread messages should self destruct after a week and sender notified.
- One of the key uses of Skype for me is that green check showing me whether I have connectivity or not.
- There is a fine line between experience and prejudice
- Europe must introduce the concept of personal bankruptcy if it wants people to take the business risks that innovation requires.
- Entrepreneurs who are afraid of VCs taking over their company forget that VCs are VCs because they cant be entrepreneurs.
- As much as you may like your smartphone or iPad, dont you love it when you go back to your laptop?
- 3G is great (when you can’t find WiFi)
- A weakness of democracy is that it takes very different skills to get elected than to govern.
- Made in USA sells in USA, made in Japan sells in Japan, made in Germany sells in Germany, made in Spain does not sell in Spain, why?
In this video you see my son Tom and I conducting a simple, yet important experiment, that allows you to approximate the speed of light only using a microwave oven and cheese. How? Well the speed of light is equal to the frequency times the wavelength. And a microwave oven comes with an indication in the back that shows the frequency. Ours is 2450 MHz. So then all you need to do is to melt cheese in a plate and with a simple ruler measure the distances between the first two areas in the cheese that start melting. In order to do this it is important that you prevent the platter of the microwave from turning. For other details just watch the video.

Wael Ghonim Google Executive, from Jail to #TED
Published by MartinVarsavsky.net in General with No Comments
Wael Ghonim over video at #TED. Before the Egyptian revolution everyone was scared except a few and those were beaten up. We are not happy when we see some Egyptians eating trash while others steal millions. The Egyptian uprising started with a Facebook page honoring man tortured and killed by Mubarak. First demonstration was thousands of people in Alexandria, a silent stand. The regime attacked them regardless of how peaceful they were. But people kept protesting, and Tunisia came. Wael was detained for 12 days, blindfolded, handcuffed, he says he does not want to talk about how he was treated. I assume he was tortured. Then he was let go and when he did he saw a changed world. When he saw that he wrote “we are going to win because we don’t understand politics”. We are going to win because we are willing to stand up for our dreams. Egyptians felt freedom approaching. The power of the people is much stronger than people in power.
