Cardixx vs SubSchool

Cardixx is a social networking and event tool designed to transform traditional contact sharing into a complete networking experience. Co-founded by Oğuz Atılan, Cardixx goes beyond basic digital, printed, or NFC business cards by helping professionals build, manage, and expand their real-world connections.

Rather than simply storing contact details, Cardixx supports the entire networking workflow. Users can build digital business cards, check in at events, discover nearby professionals, and establish meaningful connections in real time. Available on both mobile and web platforms, it bridges the gap between exchanging business cards and uncovering actual professional opportunities.

SubSchool is an advanced all-in-one educational platform engineered to transform how educators create, deliver, and monetize learning materials. Leveraging state-of-the-art AI architectures alongside specialized models such as Terra and Sol, the platform automatically converts existing media—including raw video recordings, books, tutoring sessions, and syllabus outlines—into structured, editable courses and targeted follow-up homework. This significantly reduces the administrative and curriculum design burden for educators while maintaining high pedagogical standards. Beyond rapid curriculum generation, SubSchool excels at multi-modal assessment and student management. The system automates the evaluation of complex, open-ended student submissions such as essays, spoken video interviews, photo assignments, and presentations using custom grading rubrics, all while preserving human-in-the-loop teacher oversight. With integrated one-on-one and cohort tutoring workflows, automated scheduling, entry-to-exit progress analytics, and Codex MCP integrations for direct content synchronisation, SubSchool delivers a comprehensive, modern end-to-end learning environment for teachers, tutors, and educational institutions.
