  • Language-learning app Duolingo has filed for an IPO on the Nasdaq under the ticker symbol “DUOL”.
  • The company did not confirm how much it was seeking to raise in its IPO or what its target share price is.
  • In the first quarter of 2021, Duolingo saw 97% growth compared to the same quarter in 2020.

Language-learning app Duolingo filed for an initial public offering on the Nasdaq under the ticker symbol “DUOL” on Monday, but did not disclose its valuation or share price targets, Securities and Exchange Commission documents show.

The app, whose last confirmed valuation was $2.4 billion in last November, advertised its revenue and subscriber growth to potential investors in the SEC documents alongside its position in the market.

The app maker noted 97% revenue growth to $55.4 million in the first quarter of 2021, compared to the same period last year, where the app made $28.1 million. In 2020, Duolingo saw 129% year-over-year revenue growth, as revenue more than doubled from $70.8 million in 2019 to $161.7 million in 2020. The app noted losses worth $13.5 million in the first quarter of this year, compared to $2.2 million in the Q1 of 2020.

As of March 31st 2021, Duolingo reported 40 million monthly users and 1.8 million paying subscribers. 72% of its revenue came from subscriptions, which unlock an ad-free experience and additional features on the app.

Duolingo, which is backed by CapitalG, which falls under the umbrella of Google’s parent company Alphabet, offers users free access to courses in 40 languages, including endangered ones, and focuses on gamifying the learning experience to attract and motivate users. Additionally, it offers the Duolingo English Test that can, for example, be used by international students to prove their English proficiency when applying for university in English-speaking countries. 11% of the app’s revenue came from these tests and other revenue combined in the first quarter of 2021. The remaining 17% of revenue was made through advertising.

Within the language learning market, online education is the fastest growing segment and will grow to $47 billion in 2025, up from $12 billion in 2019, according to HolonIQ data cited by Duolingo in its IPO prospectus.

Goldman Sachs, Allen & Company, Evercore ISI and Barclays will lead Duolingo’s IPO offering. Two classes of stocks will be for sale, with class A shares being equivalent to one vote and class B shares equal ling 20 votes, the SEC filing shows.

Earlier this week, Renaissance Capital data showed that the second quarter of 2021 was the busiest quarter for IPOs since 2000 and that IPOs have staged a comeback after falling steeply in May this year. On average, IPOs saw returns of 34% in the last quarter.

The headline has been amended to reflect Alphabet does not back Duolingo directly, but rather indirectly through its CapitalG fund.

Japanese Language Learning IPhone 4x3

Whether you love Japanese literature and cinema or hope to travel to Japan someday, learning the language can be a great way to feel more connected to the culture (and spend any free time at home right now). Japanese has also seen a steady uptick in learners, reaching close to 4 million, according to a 2018 survey from the Japan Foundation, making it potentially easier to find fellow Japanese language students to practice with online.

Learning Japanese can be daunting – it’s ranked as one of the hardest languages to learn by the US Foreign Service Institute. It has a lot of moving parts, from mastering the three different writing systems (hiragana, katakana, and kanji) to learning grammar that’s structured differently than English. 

Luckily, tools and apps for learning Japanese abound, from robust online courses to quick kanji flashcards. Many of these options are free or have free trials; others offer certification to add to your LinkedIn or resume. Whether you’re interested in casual self-study or intensive, university-style cramming, there’s a platform for you. 

14 online courses, apps, and resources to learn Japanese:

The popular Tofugu website and blog about learning Japanese spawned WaniKani, a web-based application for learning kanji and vocabulary. The WaniKani system uses repetition and mnemonics along with digital flashcards.

The popular language app Duolingo offers gamified learning with a cute owl mascot to cheer you along.

The app is totally free and can be used on iOS, Android, or desktop. An ad-free version is available for $6.99/month after a free 14-day trial.

10 free or affordable online courses, apps, and books to learn Russian, from Duolingo to Rosetta Stone

Russian Language Learning IPhone 4x3

During the pandemic, many people are using the extra time at home to learn a new language (or brush up on an old one). 

If you’re interested in learning Russian, there are two things you should consider. First, figure out what you are learning the language for. Do you want to be able to read “Anna Karenina” in its original language? Watch “Solaris” without captions? Speak to a loved one in their native language? Deciding which facet of the language you most want to focus on – writing, reading, listening, or speaking – will aid you in finding a curriculum and the best courses for your needs.

You should also prepare to learn a new alphabet. Russian uses Cyrillic, an alphabet system that tends to look deceptively like your standard ABCDs. For instance, the “H” letter in Russian actually makes an “N” sound, while a backwards “N” symbol ( “и”) makes an “eee” sound. Russian is also a gendered language, meaning nouns, verbs, and adjectives have to be in accordance with feminine, masculine, or neutral genders. 

However, don’t get discouraged. Any challenges you might encounter are worth the work of opening yourself up to a wonderful language, steeped in a rich and storied history with over 258 million speakers worldwide.

With that, here are the 10 best online resources to kick off (or resume) your Russian-learning. 

Here are 10 free or affordable online courses, apps, books, and videos to learn Russian:

For reading and writing

Price: Free

Length: 80 modules 

Duolingo has a solid reputation for being a reliable language-learning application, and for good reason: its fun, gamified content still teaches you a lot. Each module focuses on a specific subject, ranging from places to common phrases. The more you advance, the more specific the modules grow. Another helpful facet of Duolingo is that it challenges you to practice everyday, offering incentives in the form of “XP points” which are a great way to track your progress and keep you practicing. All in all, it’s a great application if your focus is to learn the basics of how to read and write. 

Price: Free

Length: Varies

If apps aren’t your thing and you prefer clicking around a website, this one is the best of the best. With 38 grammar modules, 18 phrase lessons, 16 quizzes, and plenty of games, this website offers enough resources to get you started. Beginning with the alphabet and general Russian sounds, you will be able to practice reading different phrases across a range of topics, ranging from family to school to countries and nationalities.

Price: Free with 7-day trial; $49 a month to keep learning after trial ends

Length: About 4 months (4 courses total)

Coursera courses are often offered by universities, which is helpful as you have the opportunity to hear real-life, practical diction. Most courses resemble ones you would take in a college-setting: that is to say, they offer quizzes, readings, and video instructions. Coursera courses are similar to Duolingo in the fact that there is little opportunity to practice your speech; the main difference between the two is that Coursera requires longer learning sessions, as each module takes around 1-2 hours to complete, while Duolingo is more short-term and can be used while on the go. Recognizing which method works best for you will help you decide between the two (although you can certainly do both in tandem!) 

Price: $31.49 on Amazon

Length: 234 pages

Having a physical textbook can help immensely with your language learning, and “Sputnik” can act as a fantastic supplement to any one of the aforementioned apps. Written by Dr. Julia Rochtchina, who also developed the Russian For Everyone website, this textbook offers concise explanations for common grammar and vocabulary questions, and provides subsequent work problems. It’s also great if you’re looking for a screen-less learning option.

For speaking and listening

Price: $20 a month (the more months you register for, the less it costs per month); there are some free modules as well 

Length: Varies based on the class

Babbel has a voice recognition feature which helps it stand out from the other learning platforms on this list. While using it via the Babbel website, you have an option to vocalize words and get feedback on your pronunciation — it’s not as effective as speaking with another human being, of course, but it’s certainly a start and can help you pin down the Russian sounds that don’t exist in English. The module exercises resemble the ones found in Duolingo (i.e. matching Russian words to their English translations; matching Russian words to pictures), so if you like Duolingo’s structure but want more speech practice, Babbel might be a great fit.

Price: Free with 7-day trial; $14.99 a month to keep learning after trial ends

Length: Varies

Rosetta Stone is one of the oldest language-learning resources around, and its continued relevance is testimony to its merit. Rosetta Stone offers many resources in order to immerse you in Russian as you’re studying it: you’ll have phrasebooks, audio companions, and moduled courses as guides. What is most valuable about Rosetta Stone is that it offers live tutoring sessions where you can practice your speech and pronunciation. It’s an invaluable tool for truly learning Russian (though it does cost extra).

Price: Free 

Length: Videos range from 2 minutes to 1 hour in length

Like learning a language through watching TV, these free YouTube videos are great in combination with some of the other courses listed in this article: for example, they can pair well with an app like Duolingo or Babbel, where there isn’t much verbal instruction going your way. The videos cover many different topics, from the alphabet to specific conversational phrases, and are great for getting accustomed to listening to the language. 

For immersion and practice

Humans are social creatures and there’s only so much learning we can do via applications, no matter how thought-out or accurate they are. This is why italki is such an invaluable app: speaking with a tutor will help you not only practice back-and-forth conversations, but get corrections on any pronunciation mistakes in real time. This can also help you key-in to cultural aspects of the language which, in focusing on grammar and vocabulary, applications gloss often over if not miss altogether. You can choose from a number of tutors to see who best fits your needs. 

Price: Free

Length: Varies

Brainscapes’ flashcards will be ineffective if they’re the sole resource you choose: they offer no formal instruction, they simply provide already-made flashcards that are separated into helpful categories like colors and animals. These flashcards (separated into helpful categories like colors and animals) will help you if you’ve completed one of the aforementioned courses and feel confident in your reading skills and ability to learn new words. There is also a function that allows you to make your own flashcards to practice anything you feel needs reinforcement. 

Price: Free with Netflix subscription

Length: 2 hours

Watching engaging Russian TV and movies can help you familiarize yourself with the language more quickly and naturally. “Dovlatov” (2018) from Russian director Aleksey German, Jr. is a nuanced portrayal of the life of Russian-Jewish writer Sergei Dovlatov during the 1970s. Not only is this film an excellent peek into Soviet-era Russia, but it also offers a great opportunity to exercise your ear. Watch the film with English subtitles when you’re just starting out to ensure that you catch the meaning of the speech — when you feel more confident in your reading, you can watch the film with Russian subtitles, which can help you match the spoken words to their written counterparts and vice versa. 

The bottom line


Russian is a complex yet rewarding language as well as a window to a rich culture. Whether your intention is to learn the basics or achieve fluency, it’s worth embarking on this linguistic journey. 

Удачи! (Good luck!)
