Kumo Labs

Predictive maintenance for mid-size manufacturers in Japan and Korea

🇯🇵 Tokyo and Osaka · Founded 2023 · 11–50 people

SeedAIManufacturingIndustrial IoT

Kumo Labs warns factories before a machine fails. Clip-on sensors stream vibration and temperature data, and our models flag problems days in advance, so maintenance happens on a planned day instead of during a breakdown. We work with mid-size manufacturers that do not have a data team.
