Team

International team, strong in analytics

KYOS software is built on knowledge, skill and commitment of our team. To reach this, KYOS employs a talented team of quantitative developers and IT programmers. Almost all finished one or more relevant MSc. in Mathematics, Econometrics, Finance or Physics, and a large percentage holds a PhD.

Our products and services add value. KYOS’ software and advisory services contain state-of-the-art modelling techniques, and they are primarily developed to make work easier. Our developers have worked in energy trading companies and therefore realize what the specifications of a good product are. It is our core strength to translate a sound analytical approach into a useful service.

Our head office is in Haarlem, The Netherlands, about 20 km away from Amsterdam.

For the Japanese market, we have a strategic partnership with Mitsubishi Research Institute (MRI) in Tokyo, as well as a local representative in Yokohama.
