Experience
Agora by Upgrade Education
https://agora.upgrade.educationAfter the matching, the student can meet their mentor via Agora's Jitsi-based videoconferencing platform or message them directly via the PubNub-based chat interface. Whenever the user is unsatisfied with their mentor, i.e., rates their mentor three stars out of five, the customer success department gets an instant notification alongside the student's contact information to keep the service quality at the highest standards.
Agora might have come out of a necessity during the pandemic, but it led to the international expansion of Upgrade Education and helped them reach an industry-leading NPS of 70.
Sesizez
https://sesizez.app/The application locates the user and then looks up the address using the OpenStreetMap API. Afterward, the application determines which authorities to direct that message to based on location and the type of complaint and pre-fills the body of a new email with that information and a template for that specific complaint type.
Prepi
Prepi assesses the mathematical skills of high school students and then provides a 100% personalized learning plan that would constantly adapt to their strengths and weaknesses. This algorithm, combined with the proven science of learning concepts, would help students study for the high school mathematics final exam as efficiently as possible.
