Unicorn Utility

Duolingo is the undisputed market leader in mobile language learning, evidenced by a $14B+ market cap and global brand recognition. While the submission data itself was sparse (leaving active user counts blank and providing generic technical tags), the public verification of the entity confirms immense real-world utility and traction. The project scores near the top of the scale due to its validated massive adoption and financial success, though the score is slightly tempered by the lack of technical detail in the specific form submission.
