Exclaim is targeting the physical maintenance gap in AI data centers: 800V DC racks and denser infrastructure make routine tasks such as replacing drives or reseating optical transceivers more hazardous, while facilities are scaling faster than technicians can be trained and hired. Its $4.95 million pre-seed bet funds first prototypes, robotics hardware, and engineering hires in an attempt to make rack-side maintenance autonomous, with remote-operator fallback when the robot lacks confidence.
