Knihobot is a re-commerce platform where over 5 million books have already changed hands. Every day, we send around 22,000 books to new homes and gain thousands of new customers — figures we plan to double within the next year.
We're among the top 10 fastest-growing tech startups in the CEE region and have won the Heureka ShopRoku award for 2021, 2022, and 2023.
We operate in four European markets (CZ, SK, AT, and DE) and have big plans, especially in Germany. In our high season, we spread the idea that a second-hand book makes a great holiday gift — and together, we aim to make second-hand the new European standard. A new warehouse in Prague's Hostivař and €4 million from our latest funding round help us accelerate this mission.
Sounds exciting? Take a look at the position and join us in conquering the European book market!
