Hi HN, we're the founders of Filadd (https://courses.filadd.com/). 80% of students in LatAm (Latin America) need private tutoring classes to prepare for university admission exams. The system is centralized and extremely high-stakes: exams only happen once a year and based on your score on the exam you can basically choose your university. If you don’t get the desired score, go home and come back the next year. So there is a huge market of private coaching for these admissions, and lots of academies that give face-to-face classes like a school. We offer online courses that include one-on-one tutoring to students who are preparing these exams. We have a revenue share business model with the teachers who work with the students—not a common model in the region. We also use Data Science to identify how well students are performing and we offer them the exact content they need to study.
