Loora raises $22 million to build AI English tutor to help people get better jobs.

Loora raises $22 million to build AI English tutor to help people get better jobs. 16 September 2026 Key Takeaways * Loora secured $22M in Series B funding to scale its AI English tutor. * The app has 12 million downloads and a near five-star rating from over 300 reviews. * Loora is built for serious learners. Handles real-life conversations about work, interviews, and business. There are hundreds of English apps that teach you by matching words and tapping pictures. However, when you have to present a proposal to your boss, that is definitely not the best time to take pictures. Right now, more than 1 billion people are learning English because they want better pay. To solve this, Loora raises $22 million to build an AI tutor that can make people speak English fluently. Loora raises $22M in Series B funding. Loora, the AI English coaching app, has raised $22 million in Series B funding. The total raised for Loora is now over $43 million. The startup raised $12M Series A in 2023, led by QP Ventures and $9.25M seed before that. Loora was founded by Roy Mor and Yonti Levin. Both are engineers who worked on AI language models. The company is based in Tel Aviv and New York with a team of 25+ people. An AI coach that corrects you. Loora is not Duolingo. Here's how it works: Open the app, pick any topic. Loora has a real voice conversation with you. While you talk, it gives you live feedback. For example, the AI can respond, "You said 'I am working here 2 years.' Better: 'I have been working here for 2 years.'" It also scores your pronunciation and accent. Most AI apps just use ChatGPT. Loora says they built their own system. They only use their own learner data and their own training method. They call it LLMs - Language Learning Models, not Large Language Models. It remembers your mistakes and pushes you. It costs $15 per month or $120 a year. You can practice at 2 AM before an interview. Over 70% of users use it for work. According to CEO Roy Mor, Loora pushes beyond most apps that are limited and gamified. Mor explains that "Loora was built for serious learners trying to get fluent for personal and professional growth." 12 million downloads and growing fast. Loora has 12 million downloads on Google Play alone. 610k downloads in the last 30 days. 4.88 stars from 330,000 reviews and is ranked #2 in Education. 15,000 paying users in 2023, grew 8x in ARR that year. Now estimated in hundreds of thousands. There are no ads, purely subscriptions. Loora says their retention keeps improving because their AI keeps getting better from their own data. The $22M will make the AI better at remembering, understanding accents, and role-playing. Imagine practicing a full Google interview with follow-up questions. The round will enable the startup to expand beyond iOS and Android. They launched Android in 2024; now, they want B2B. English is still the internet's language. If you can't speak it fluently, you get paid less. You get fewer jobs. Old tutors cost $30 per hour. Old apps don't make you fluent. Loora wants to be in the middle. They're like a personal coach that costs less than $1 a day and is available anytime at all. If this works, millions of people will be able to speak English without shame or fear of anything.
