Since 1975, Infinite Corporation has helped the world's largest enterprises modernize their IBM midrange systems — from the System/32 to today's IBM i. An IBM partner from the start and a Microsoft partner since 1980, with our first system delivered to Honeywell. Today our software runs in more than 100,000 installations across 56 countries.
In 1975, Infinite Corporation shipped its first migration toolset for the IBM System/32 — and delivered its first system to Honeywell. An IBM partner from the start, and a Microsoft partner from 1980, Infinite extended its tools across every generation of the IBM midrange. As IBM advanced the line — through the System/34, System/38, System/36, and the AS/400, and later the iSeries, System i, and IBM i on Power — Infinite kept pace with complete migration and modernization coverage. Fifty years on, our software runs in more than 100,000 installations across 56 countries.
Infinite is founded and ships its first IBM midrange migration toolset. Our first system is delivered to Honeywell, and our IBM partnership begins.
IBM brings multi-user, multitasking computing to the midrange. Infinite extends its toolset to match the new architecture.
IBM introduces an advanced architecture with a built-in relational database and single-level storage — the design that becomes the foundation of the AS/400.
The successor to the System/34 keeps thousands of shops productive. Infinite supports the full midrange family across both architectures.
IBM unifies the midrange into the AS/400, carrying the System/38's architecture forward. Infinite delivers migration and modernization coverage from the start.
The AS/400 becomes the eServer iSeries. Infinite's toolset grows with the platform and its expanding workloads.
Rebranded System i, the platform gains new capabilities — each matched by Infinite's migration and modernization tools.
System i and System p converge into IBM Power Systems running IBM i. Infinite provides complete coverage of the platform and its applications.
Infinite i and its add-ons — Infinite UI, Infinite DataLink, and Infinite Studio — move IBM i applications to native Linux on AWS, Azure, and GCP. 100,000+ installations across 56 countries, and counting.
Trusted for 50 years by the world's largest enterprises
Partnering with the platforms our customers run on — IBM since 1975, Microsoft since 1980
Infinite i is the core platform — it recompiles your RPG, COBOL, CL, and DDS to run natively on Linux. Infinite UI, Infinite DataLink, and Infinite Studio are add-ons that run on top of Infinite i: each extends the platform, and none runs without it.
The core platform — recompile RPG, COBOL, CL, and DDS to native Linux on AWS, Azure, or GCP. 45–60 days. Half the cost of staying on Power.
