Learning to speak English fluently can be a real challenge, especially when you’re doing it on your own. That’s where Stimuler, a fast-growing AI-driven English learning app, comes in—and it just got a major boost. The company has raised $3.75 million in a pre-Series A funding round led by Lightspeed and SWC Global, with support from investors like M Venture Partners, Rebright, Force Ventures, GradCapital, and Operators Studio.
With this funding, Stimuler plans to step up its game—investing in stronger AI tech, hiring more talent, and expanding its reach to learners around the world, especially in Southeast Asia and Latin America, where demand for spoken English skills is booming. The company also has ambitious plans to grow its revenue fivefold over the next year and a half.
What makes Stimuler stand out is its voice-first approach. It acts like a personal English-speaking coach in your pocket, offering real-time feedback on pronunciation, grammar, vocabulary, and fluency. Whether you’re prepping for a job interview, trying to boost confidence in everyday conversations, or simply brushing up your skills—Stimuler offers a smart, accessible way to learn.
And the world is clearly paying attention. The app has already crossed 4 million downloads, with over 45,000 paying users on Android and iOS. While it’s built in India, most of its users are from outside the country, with strong traction in Indonesia and other international markets. Today, people in 175+ countries are using Stimuler to improve their spoken English.
It’s a big moment for the startup—and a sign that AI-powered education tools are just getting started in reshaping how we learn.
