Modernizing Vendor-Locked Legacy Systems Without Breaking the Business
We help enterprises modernize mission-critical legacy systems, including IBM-era stacks and proprietary languages like Natural, into modern, cloud-ready architectures, using custom AI-driven agents and deep engineering judgment.
The Reality of Legacy Modernization
If your systems were built decades ago by vendors like IBM, you’re likely facing the same challenges:
"Building AI coding agents for legacy systems is a dead end. Modernization is the only sustainable path forward."
Why Platforms & Traditional Vendors Fail
Most “AI modernization platforms” assume a one-size-fits-all solution exists. In reality, business logic is deeply entangled with decades of decisions.
- Responsibility is pushed back to client teams
- Customization turns into slow services
- New vendor lock-in introduced
United Techlab Approach
We don’t split responsibility. We modernize using AI as an internal engineering accelerator, not a product you need to operate.
- Outcome-Owned: We take full responsibility.
- Deep Analysis: Understanding code & data flows first.
- No Lock-in: You fully own the new system.
Our Process
Deep Understanding
Analysis of code, data, and edge cases.
Modern Architecture
Design full system (stack, cloud, CI/CD) upfront.
New System First
Modern environment running from day one.
Incremental Migration
Module-by-module migration with CI/CD.
Continuous Validation
Progress is measurable and auditable.
Our Guarantees
- Functional equivalence guarantee
- Incremental production deployments
- Milestone-based payments
- Up to 50% refund if expectations not met
- No new proprietary lock-in introduced
- You fully own the code
Engagement Model
We start with a fixed-scope pilot to prove our value.
Pilot Phase
Typically a module or standalone service. Designed to prove modernization approach.
Full Program
Complete transformation programs. Scaled based on system complexity and size.
