Our mission

Efficiency through smart design

From data-intensive transaction processing to data management solutions for AI, we design scalable, green, energy efficient, and smart data systems solutions.

Innovation in novel contexts

We constantly apply novel data system inventions into old and new business domains and use-cases.

Research-as-a-Service

We conduct scientifically rigorous user studies, lab tests, performance testing, and literature syntheses on demand.

Training and propagation

We provide on-demand training in data systems topics such as DBMSs, querying, optimization, and reliability, as well as accessible propagation of recent advances in data systems.
