DSI was founded in 1989 by Dr. Gerald Belpaire and Samuel Aizenberg, in response to a demand for trading systems that provide real-time facilities for monitoring prices, positions, profitability and risk. We are located at 116 John Street, Suite 308, New York, NY 10038.

Decision Software, Inc. (DSI) is devoted to the design, engineering and implementation of trading systems for the institutional financial community. It has maintained a singular focus on developing superior software systems for a "front and middle-office" niche, and is not engaged in peripheral business enterprises. Decision Software's primary target market is broker/dealers and banks involved in fixed income and money market sales, trading, and funding. Our secondary target market is institutions involved in fixed income portfolio management.

Decision Software has created a unique brand identity for DSTS, by enlisting traders and their managers in the actual product design and engineering. As such, all DSTS processes maintain a high correlation to business intent. This flattens the initial learning curve for end-users, and makes for easy, ongoing use of the system. Consequently, DSTS has proven to be quite popular with traders, and is regarded as a "user-friendly" system.

DSI is also widely recognized among clients, consultants and systems integrators, as employing market-leading technology, open system standards and superior software engineering. These factors allow for such things as maximum real-time performance, ease of use, data leverage, incorporation of proprietary client analytics, and real-time data access. The result is a trading application that can leverage data firm wide.
