CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.
Codemonkey is an interactive online platform designed to make learning code fun for kids from 5-14 years old. Through engaging games and challenges, it introduces programming concepts in a clear and accessible way. As children write code to help a monkey complete different tasks and puzzles, they develop essential skills like logical thinking, problem-solving, and understanding algorithms. With step-by-step instructions and immediate feedback, Codemonkey provides a supportive and enjoyable environment that makes getting started with coding both easy and exciting.

CodeMonkey's answer:
CodeMonkey was founded in 2014 by Jonathan Schor, Ido Schor, and Yishai Pinchover, inspired by their experiences teaching kids to code through playful activities. They envisioned a platform that would make coding accessible and enjoyable for children, blending real programming languages with engaging, game-based learning. Launched in Israel, CodeMonkey quickly gained global traction, reaching over 34 million students in 206 countries by 2024 . In 2018, it was acquired by TAL Education Group but continues to operate independently, expanding its offerings to include courses in AI, data science, and digital literacy. Today, CodeMonkey remains committed to empowering young learners worldwide through fun and effective coding education.
