Quartet Financial Systems (QuartetFS) was founded in response to demand from industries with complex business models and a need to make timely decisions. The Company is privately held by its founders and has offices in New-York, London and Paris.

QuartetFS founders each have at least fifteen years of experience in developing, distributing and implementing capital markets systems. As such each partner brings specific expertise and in-depth knowledge of capital markets, leading-edge technology skills, and extensive implementation experience.

Having listened to the industry and seen first hand what is needed to run complex markets, QuartetFS has used the teams’ knowledge and experience to marry Business Intelligence with Complex Event Processing (CEP) technology tools. This means that our clients have a clear picture of their position in real-time, by tracking ongoing activity and events and are able to draw on the right information, to make informed decisions faster and with greater confidence.
