About Dataspex

Tomorrow’s telescope will be a “total telescope”, where the overall design integrates telescope hardware with computer hardware and software; all observations will be inspected, stored and queried very quickly for scientific analysis. The science is in the data and smarter management of the data will raise your science to the next level.

Dataspex is specialised in managing big data streams on modern hardware and in finding the right solutions for your system. We can assist you with the design, software development, implementation or improvements of such systems.

Dataspex is a spin-off company of the Netherlands research institute for mathematics and computer science (CWI).
