XStream S.r.l. was founded in September 2018 with the aim of developing, producing and marketing a range of software products capable of bringing simplification and efficiency in the governance of technological environments in Mainframe Data Centers, modernizing their organization and reducing the cost structure. XStream originated from the meeting of a group of system engineers and integrators who decided to combine their know-how in order to find innovative solutions intended to optimize Mainframe Technology and IT Governance Management. zStream, the first module to be conceived, combines solutions and tools developed in over twenty years to support the day-to-day consulting activities of XStream founders. Version 1.0 was established in 2005 to go into production in the Mainframe environment of Banca Intesa Sanpaolo, which was the first to recognize the value of the solution and believe in the product. In 2009 Pulse srl was conceived to develop further specific solutions for Mainframe Management in order to merge them into a Suite of Products. In 2018 XStream was launched as a spin-off operation of Pulse srl, and was soon supported by the i3P incubator of the Polytechnic of Turin and the UniCredit Start Lab Accelerator of UniCredit Banca.
