Every serious language learner already considers Duolingo to be trash. It's not real competition.

Our market is different - ISSEN is more focused on intermediate and advanced students, and especially those that are willing to use a more difficult app in order to learn faster.

Also, having the AI voice tutor as our main feature allows us to iterate quickly, and be well positioned for future improvements in AI models.

As for marketing and GTM, we're in the super early stages, and there is definitely a lot of competition out there, it won't be easy.
