yonder AI Modernization Framework (YMF)

AI-Native Modernization

Reach 10% - 50% sustainable velocity gain.

Since the early 1990s, we have modernized your large, rich, complex solutions that your customers depend on to run their businesses. Now AI accelerates the transformations, yet it still requires engineering accuracy to modernize correctly and without explosive token costs. So, throughout the modernization, your people and ours stay in control.

three decades of modernization

We have used our experience to create YMF, which safely applies AI to transform your software.

Yonder is an innovation partner with a long history in software services, and most of it spent modernizing large, mission-critical solutions for VMS software companies. We know where these projects go wrong because we have navigated them many times before. AI doesn't replace that judgment; it accelerates it.

  • 30+ years modernizing mission-critical software
  • 65+ large-scale modernizations delivered
  • 800K+ lines of code in a single estate, handled with confidence
  • 30+ specialist industries and regulated markets served
what we believe

AI accelerates the coding.
People govern the outcome.

our approach

One approach
has three layers

Think of it as a method, process, and machinery: a way of working, a repeatable path, and the purpose-built tools that make it fast and dependable for your specific technology.

  • method / how we work

    Agents build. People govern.

    We call this our AI-DLC. This is how we run the work with AI Agents do the routine building from day one, while we, your and our people, direct and approve every step.
  • process / what we do

    A clear path, every time.

    The Yonder AI Modernization Process (YMP). These are the steps we follow One repeatable sequence, from understanding your system all the way to running its modern replacement.
  • machinery / what powers it

    Tools tuned to your technology.

    Our AI Modernization Framework (YMF) does the heavy lifting Purpose-built tools and AI agents, tuned to your specific platform. This makes a faithful, largely automated rebuild possible.
  • Method
  • Process
  • Machinery
We modernize any legacy stack. Some automated accelerators are live today, with more built on demand.
the journey

YMF, a clear path from where you are to where you are going.

Think of it as a method, process, and machinery: a way of working, a repeatable path, and the purpose-built tools that make it fast and dependable for your specific technology.

  • 01 Scan

    Understand what you have (every screen, rule, and data flow) read automatically from the source code itself.

  • 02 Model

    Design the future together, from today's evidence-based picture, and decide what to keep, change, or leave behind.

  • 03 Build

    Rebuild at speed. We govern architecture and quality and AI constructs or assists for rebuilds, and parts you choose to redesign.

  • 04 Decorate

    Once the core is running, add the modern value, such as AI features, mobile access, self-service portals, only where valued.

  • 05 Validate

    Independent testing and have your own people confirm the new solutions does everything it must.

  • 06 Maintain

    Run and evolve the live software product. And then we hand the knowledge over to your teams for the long term.

what it means for you

The results your board cares about.

  • Lower risk A governed, evidence-backed path replaces the leap of faith that a big-bang rebuild demands.
  • Faster time to value Modern capability reaches your customers far sooner than a rebuild-from-scratch would allow.
  • An AI-ready product A modern foundation that can carry the AI features your market is starting to expect.
  • Retained knowledge Decades of business logic is now captured as documentation rather than trapped in one person's head.
  • Predictable cost Scope, effort, and price are grounded in what your system actually contains, not a hopeful guess.
  • Control retained You steer every meaningful decision, from what to keep to when to go live.
