Hey there! I'm Simon, the CEO of Ling App. At Ling, we help people learn languages - especially those that aren't always easy to find in traditional courses. Whether it's Thai, Serbian, or even Khmer, we make learning fun and accessible through our mobile app.

We’ve grown a lot over the past few years, hitting $3 million in revenue last year, and we're aiming for $7 million in 2025. To get there, we're leveling up our team and looking for top talent to help us grow.

Our team is about 45 strong, with half of us in Thailand and the rest spread across the world.
