Our Product

Classtime enables teachers to create questions on an internet-connected device (mobile phone, tablet, PC/notebook), push them to all student devices, and track the performance of a class immediately in a class session. The teacher receives valuable information about the individual student's performance and can intervene as deemed appropriate, thereby improving the overall learning progress of the class. By answering the questions, all students are fully engaged, which can also be analysed after class and even over time to measure a single student's or the entire class's development. Some of our AI initiatives include comment generation, reading and listening content generation and evaluation of student answers.

Classtime is trusted by more than 430,000 teachers and various clients (schools/businesses) globally.

Curiosity - Always continue to experiment and learn.

Impact - Always focus on generating value for society.

We don't pride ourselves on large employee numbers, but rather on exceptional impact per team member. We expect exceptional ownership and responsibility, not only for your tasks, but for our impact on society. Don't go improve the next ad platform, help us in our attempt to shape the future of education. If you can throw a punch with impact, then use both fists, not only 50%.

Honor - Act with integrity, always help a friend or rival.

Because we believe that creative, curious people will honor future generations and learn to solve the world's biggest challenges for the long term. This is what Classtime is all about – and we will relentlessly strive for our goals and keep pushing the frontiers of education. With our friends and “co-opetition”. This is 100% Classtime.
