About Us

Redefining storage is our defining moment

From the dawn of the disk era, storage has been defined by its limits, creating barriers to extracting maximum value from an enterprise’s most valuable asset – data. Today, clouds are driving needed agility, but storage has not kept pace. Until now.

Datera is tearing down storage barriers through a radically simple idea – defining storage by its data, driven automatically by applications.

Leadership Team

Our vision and execution are driven by experienced and passionate technology innovators and executives from leading companies spanning the computing, networking and storage industries.
