Prompt K, operating as PROMPT-X in Japan, is a specialized technology firm focused on time-series data management, a niche but increasingly critical domain as IoT and real-time analytics gain traction. Founded with the vision of making time-series data as universally accessible as graphical user interfaces once made computers, the company has developed proprietary database architectures and BI tools tailored for temporal data streams. Their product suite targets industries where sensor data, operational telemetry, or transactional timestamps are abundant but underutilized.

While the company has not disclosed revenue or funding figures, its client base includes agricultural and healthcare sectors in Japan, suggesting a focus on vertical specialization over horizontal scalability. Recent expansions like the Kagoshima office opening in 2026 indicate regional growth, though international presence remains unconfirmed. What stands out now is their dual emphasis on both infrastructure (CLOUDSHIP® database) and application layers (RealBoard® analytics), attempting to own the full stack in a market where most players specialize in one or the other.
