About McObject
McObject was founded when its team—senior executives and technologists from the database and embedded systems industries, recognized an emerging shift: systems once considered hardware—telecom and networking equipment, industrial controllers, avionics were becoming data-driven. These environments needed data management that was not just fast, but compact, predictable, and, above all, proven in the field.
That insight led to the company’s founding in 2001 and the introduction of the eXtremeDB In-Memory Database System (IMDS), the first in-memory DBMS designed specifically for embedded systems. Since then, the technology has been adopted across virtually all embedded markets, supporting applications where low-latency data access and reliability are not optional. The product line has expanded in several directions, including support for persistent storage, SQL interfaces, IoT infrastructure, vertical storage, and AI/ML workloads. Our latest innovation, eXtremeDB/rt, stands out as a unique offering on the market, addressing hard real-time requirements with predictable behavior and direct flash access under database kernel control.
Today, eXtremeDB technologies power a wide range of embedded and IoT systems worldwide. With over 70 million deployments, McObject remains focused on delivering efficient, predictable, and adaptable data management software that keeps pace with the systems it supports.
