Shogo Uchida — Hakareru-kun founding story
Our Story

Born from
the factory floor

"Why are workers still walking to shelves and counting inventory by eye?" That question led our CEO Uchida, after visiting over 300 manufacturing sites, to build Hakareru-kun.

By combining weight sensors with IoT, Hakareru-kun can track inventory from 0.5g to tons. Selling the shelf as a complete unit — sensor, panel, and cloud — made it possible for any factory, with zero IT expertise, to go digital from day one.

The full story: development challenges, iteration, and real-world impact — told by CEO Uchida.
