For more than 45 years, H&W Computer Systems
has specialized in building mission-critical mainframe software that keeps enterprises running without interruption.
Founded in 1979 in Boise, Idaho, H&W has grown from a regional software developer into a trusted provider for Fortune Global 500 companies, higher education institutions, and government agencies.
Our focus is on mainframe efficiency, availability, and modernization of VSAM-based Applications giving organizations the ability to extend the life and value of their IBM z/OS environments rather than rip and replace.
H&W engineers and support staff are recognized industry experts in CICS, VSAM, and batch optimization, ensuring that customers get not only powerful tools but also expert guidance.
We back our products with 24/7 global support delivered directly by the engineers who develop and maintain the software — not by outsourced call centers.
Customers consistently highlight our responsiveness, deep technical knowledge, and long-term partnership approach in win/loss interviews and case studies.
