ATEO was formed with the idea that reliable technology, strong ground experience, and flexible development approach linked to efficient quality process are the best assets to reach our target: delivering software solutions that cut trade processing costs and reduce risk on derivatives, equities and OTC markets, whether outcry or electronic. Therefore all our solutions have all been developed to deliver an immediate return on investment by: Suppressing manual operations carried out by middle-office operators and replacing them by real time and fully automatic Straight Through Processing. Real time monitoring of trades. This prevents having to wait for H+1 or D+1 to detect mistakes. Providing horizontal solutions, independent from our customers current systems organisation. This reduces costs of project implementation and prevents any particular binding to other systems providers that would greatly reduce flexibility. Providing open solutions that enable free access to the stored data without requiring any specific intervention of our services. To achieve this we have developed our solutions in close partnership with our customers and all screen interfaces have been designed with the final users themselves (traders, compliance, marketing, ...). Our driving force is client satisfaction, therefore our customers have always beendirectly involved in our software development line.
