We modernize aging, platform-locked, and out-of-support software and the legacy databases behind it, making it portable, secure, and interoperable on Windows, macOS, and Linux, at a fraction of the cost of a ground-up rewrite.
The same software your team already knows, on a foundation that's secure, open, and ready for what's next.
Great software shouldn't die because its platform did. We extend its life without starting over.
Software tied to one operating system, brought to Windows, macOS, and Linux, in whichever direction you need, without losing the behavior your users rely on.
Visual Basic 6, Delphi, PowerBuilder, Classic ASP, Flash, Java applets, and old .NET Framework versions, moved onto supported, current technology.
Won't run on new hardware or a current OS version, or only as a 32-bit app? We resolve runtime and dependency problems so it works again.
Microsoft Access, FoxPro, dBase, Paradox, FileMaker, and Lotus Notes applications migrated to modern engines like PostgreSQL, SQL Server, and MySQL, with schemas, queries, forms, and reports carried forward.
Business processes running on giant Excel workbooks and VBA macros, rebuilt on a real database and application that's reliable, auditable, and multi-user.
Proprietary and undocumented formats, EDI feeds, and fixed-width exports converted to open standards, with old Crystal Reports-style reporting replaced by modern reports and dashboards.
Old systems with no way to connect to anything new get modern APIs, wrappers, and clean integrations with the tools you use today.
Instrument, lab, and industrial control software that depends on serial/COM ports, USB drivers, or 32-bit DLLs, kept working on current systems.
Assessment and migration of long-running mainframe and COBOL business logic to modern platforms, with the rules your business depends on preserved.
Outdated libraries, hardcoded credentials, unencrypted data, and unsupported runtimes, audited and fixed, with a software bill of materials (SBOM) for customers and auditors who ask.
Code that only compiles on one person's machine? We recover the build, add version control and automated builds, and write the documentation. We can also work from compiled software where you hold the rights.
When a full port isn't worth it, we run legacy software safely in a container or virtual machine, isolated, repeatable, and easy to back up.
Customers still want it, but it's too old to sell or support. We make legacy products shippable and maintainable again.
Modern installers, automatic updates, and code signing, so your software installs cleanly and customers trust it.
Single-user desktop applications reworked as browser-based or hosted versions, scoped carefully so it stays far short of a full rewrite.
Scientific instruments often ship with their own data-logging software, built for a single, aging version of Windows. The hardware keeps working for decades. The software doesn't.
Every engineer on your project works in the United States, for clear communication and accountability.
Targeted modernization beats a full rewrite. We fix what matters and preserve what works.
Behavior-preserving changes, tested against your existing outputs, so nothing important breaks.
Open formats, clean code, and documentation. No lock-in, no mystery black boxes.
Most legacy software doesn't need to start over. It needs the right parts fixed.
Illustrative comparison of scope, not a quote. Every project is scoped and priced individually.
We review your software, platform constraints, and goals, then give you an honest scope and estimate.
A fixed-scope plan covering portability targets, security fixes, and data and integration needs.
We port, patch, and migrate, verifying against your existing behavior at every step.
Installers, documentation, and handoff. Ongoing support is available if you want it.
