The Caracas Startup That Turned English Into a Subscription
It started with $700, a sofa in San Francisco, and a bet that people learning English still want a human on the other end of the line. Two million students later, Open English is the accent Latin America practices in.
In 2007, a broke engineering student walked away from a business that was already working. Andres Moreno had built a small English school in Caracas, flying recent United States college graduates to Venezuela to coach Fortune 500 executives in person. The clients were real and the revenue was real. The problem was arithmetic: you cannot fly enough teachers to teach a continent. So Moreno closed the classroom, kept the teachers, and moved the whole thing onto the internet. That decision became Open English.
Nearly two decades later, Open English is one of Latin America's most recognizable education-technology brands - an online school where Spanish and Portuguese speakers learn English from native speakers in live classes that run around the clock. It has enrolled more than two million students, operates across 30-plus countries, and has raised roughly $120 million in venture capital along the way. The company that started with about $700 now teaches at a scale the Caracas classroom could never have reached.
01 / The pivotKilling the business that paid the bills
Most founders would have kept the in-person school. It had brand-name clients and steady margins. But Moreno saw the ceiling early. The model depended on scarce, expensive human logistics - visas, flights, hotels, scheduling - and none of it compounded. With roughly $700 left, he traveled to California, raised a handful of small angel checks, and built a beta version of an online classroom. The origin story that Open English staff still repeat involves Moreno sleeping on a sofa while pitching investors, an immigrant-founder narrative that has followed the company from Caracas to its current headquarters in Coral Gables, Florida.
The insight underneath the pivot was not technological. It was about what people were actually buying. In Latin America, English is rarely a hobby. It is closer to a raise - the difference between two salary bands, or between a local job and a multinational one. Moreno built the company around that reality rather than around vocabulary drills.
Most people don't just want to learn a few words in an app; they actually want to learn how to speak it because they need it to develop professionally.Andres Moreno, Founder & CEO
02 / The productThe teacher, scaled - not replaced
The defining choice at Open English is the one it did not make. As competitors raced to build software that could replace the instructor, Open English kept the instructor at the center. Its core product pairs interactive, self-paced multimedia lessons with unlimited live classes taught by native English speakers - group sessions and one-on-one coaching - available 24 hours a day. A student in Sao Paulo at midnight and one in Mexico City at noon can both find a live teacher on their own schedule.
We never wanted to use technology to do away with human interaction. A lot of other companies are trying to create software where you wouldn't need a human. We did the opposite.Andres Moreno
Around that core, the company built a family of products for different buyers. Open English Junior teaches children with gamified, age-appropriate lessons - a product that reframes the purchase as a decision parents make. Open English for Business sells corporate seats, giving companies workplace-English training with progress tracking for managers. NextU, acquired in 2015, added digital-skills and professional courses beyond language. And Open Mundo quietly turned the English school into a multi-language school, extending the same live-class engine to French, Italian, Portuguese and Spanish.
| Product | Who it's for | Since |
|---|---|---|
| Open English | Adult professionals | 2007 |
| Open English for Business | Company teams (B2B) | 2013 |
| Open English Junior | Children | 2015 |
| NextU | Digital-skills learners | 2015 |
| Open Mundo | Multi-language learners | 2021 |
| enguru | India, mobile-first | 2022 |
03 / The customerYoung professionals buying a better job
The core audience is young Latin American professionals, roughly ages 20 to 45, with strong bases in Brazil, Mexico, Colombia and Argentina, plus the United States Hispanic market. They are joined by children through Junior and by employees whose companies pay through the corporate arm. Open English crossed one million enrolled students in late 2021 and has since reported passing two million, taught by a network of more than 2,000 native English-speaking teachers. The company runs operations from offices in Miami, Mexico City, Bogota, Buenos Aires, Sao Paulo, Istanbul and Bangalore - a footprint that mirrors where its students and, increasingly, its acquisitions live.
That spread matters for a product sold on availability. Because demand is distributed across time zones, the promise of a live teacher at any hour only works if the teaching supply is large and always-on. The 2,000-plus-teacher network is less a headline stat than the machinery that makes the 24/7 pitch credible in the first place.
If you walk into an employer and you speak English, that's all the proof they need. It's very skills based.Andres Moreno
04 / The modelEnglish, sold like a streaming service
Open English is, at its heart, a subscription business. Learners pay a monthly fee - historically in the range of $70 to $80 - for unlimited access to classes, teachers and content. Positioned against traditional language schools that could cost thousands of dollars a year, the pitch was accessibility: the fluency of a private school at a fraction of the price, on your phone, on your schedule. The recurring model means the company keeps a customer only as long as the customer keeps showing up, which pushes the product toward engagement rather than one-time sales.
05 / The money$700 in, roughly $120M raised
Open English's fundraising reads like a map of investor conviction in Latin American consumer technology. After early angel money and a growth round backed by Flybridge, Kaszek Ventures, Insight Venture Partners and Redpoint, the company raised a $43 million Series C in 2012, led by Insight. In 2013 it closed a $65 million Series D led by Technology Crossover Ventures, reaching a reported valuation of around $350 million. In December 2021 it filed confidentially for a United States initial public offering - a listing it did not complete, leaving the company private.
06 / The differenceWhere it sits against the app store
The language-learning market splits roughly into two camps. On one side are the app-first brands - Duolingo, Babbel, Rosetta Stone - that lean on software, streaks and self-paced practice. On the other are the human-first schools - Berlitz, EF Education First, Wall Street English, Cambly - that put a person in the room. Open English sits firmly in the second camp but wraps it in the economics of the first: a low monthly price, a slick digital platform, and teachers available at any hour. Its live-teacher model overlaps most directly with Cambly and Berlitz, while its subscription pricing competes for the same wallets as the apps.
| Approach | Examples | Open English's angle |
|---|---|---|
| App-first | Duolingo, Babbel, Rosetta Stone | Adds real live teachers, not just software |
| Human-first schools | Berlitz, EF, Wall Street English | Cheaper, online, available 24/7 |
| Live tutoring | Cambly, italki | Structured curriculum plus subscription |
07 / What's nextBuying its way onto new maps
Where organic growth slowed, Open English bought. It acquired Turkey's English Ninjas in 2021 and India's enguru in 2022, carrying its model into the Middle East and South Asia. In 2022 it also expanded its board with executives from Google, Twilio and AppLovin, signaling ambitions beyond its Latin American home. The company has marketed AI-driven features - adaptive practice, tutoring assistance - alongside its human classes, positioning the teacher and the algorithm as partners rather than rivals. It has kept a mission thread running through the growth, too, from a 2023 campaign with footballer Richarlison that donated hundreds of thousands of dollars in courses to Brazilian youth, to scholarships for Venezuelan students.
The throughline is consistent. Open English decided early that people learning a language want to be understood by another person, not just corrected by a machine - and it built a business on keeping that person in the loop while making them reachable at scale. From a closed classroom in Caracas to a live class streaming at 3 a.m. somewhere in the Americas, the product is the same thing it always was: a teacher, on the other end of the line.
