Welcome to Millistream

Millistream is a modern market data company founded in 2008 by Per Rastin and Mats Fors. Per and Mats brought decades of industry experience with them, but no technical legacy. That meant they were able to architect their solutions using the latest technologies and development methodologies.
Millistream’s core real-time infrastructure is built for speed and throughput – taking advantage of specialised hardware, fibre circuits and co-location data centres in strategic locations across Europe. At the same time, our delivery architecture has been designed for efficiency and ease-of-use.
Low-latency clients can draw upon all of our available content via a low-level API, accessed either through dedicated leased lines or a cross-connect in one of our co-location facilities.
Millistream has also recognised the growing importance of cloud infrastructure to support clients who prioritise scale over speed. We have supported a Point of Presence in AWS for the last 8 years, and offer a suite of web solutions, including a RESTful API alongside an ever growing range of display widgets to support internet and mobile applications.
