Legacy Software Modernization
Move aging applications from outdated technologies to a modern, maintainable stack — incrementally, or rebuilt where a rewrite makes more sense.
Legacy modernization · Reverse engineering · Migrations · Business automation
We help US businesses understand, rebuild, migrate and automate existing software — from undocumented legacy applications and outdated technology stacks to CMS platforms and manual business processes. Work directly with senior engineers from the first conversation to production.
Trusted by founders and CTOs at US companies — from fast-growing startups to established 20–500 person teams.
Get an initial technical approach, timeline and budget estimate within 2 business days. Free.
No obligation. No sales handoff.
You don't need to know which framework, CMS, architecture or cloud platform you need. Tell us what's slowing your business down. We'll figure out the technical path.
Our legacy application is becoming impossible to maintain.
Nobody fully understands how the old system works.
We need to move off an old stack without breaking the business.
Our CMS has turned into a custom application full of workarounds.
Adding a simple feature takes months.
Employees spend hours moving data between systems manually.
Another vendor gave us a six-month estimate — we want a second opinion.
What we solve
Move aging applications from outdated technologies to a modern, maintainable stack — incrementally, or rebuilt where a rewrite makes more sense.
No documentation? Original developers gone? We analyze code, database, integrations and runtime behavior to recover business rules and hidden edge cases before touching anything.
Move off an outdated language, framework or database without breaking the business logic that depends on it — planned around what the system actually does, not just what it's built on.
Move from legacy CMS platforms or heavily customized systems to whatever actually fits — another CMS, headless, a custom application, or a mix. We don't sell a preferred CMS.
Replace repetitive manual workflows, spreadsheets and disconnected systems with software and integrations — from a small internal tool to a full workflow.
Not every system needs a rewrite. Sometimes the right answer is to understand what already works and extend it — properly, without starting from zero.
Need something built from scratch instead? We design and build custom applications and internal tools with the same senior-engineer, low-overhead approach.
Already have a proposal? Send us the scope. We'll tell you if the architecture makes sense, where the risks are, and what we'd do differently.
Key differentiator
Legacy software rarely behaves exactly the way its documentation says it does. Sometimes there is no documentation at all. We reconstruct the system before we propose a migration path — not after.
Free Technical Assessment
Start with a short conversation with an engineer. Share your existing system, problem, requirements, documentation — or even an estimate you already received from another vendor. Within 2 business days, you'll normally get:
Extend, refactor, migrate, automate or rebuild.
How we would solve the problem, and why.
A realistic initial delivery range.
A ballpark implementation cost.
Unknowns that could materially affect scope or timeline.
Fixed price, milestone delivery, or Time & Materials.
For systems with significant undocumented complexity, we may recommend a deeper technical discovery before committing to a fixed implementation price.
The engineer discussing your problem is an engineer who can actually build the solution.
Faster decisions, less information lost between people, less management overhead built into the project price.
We're not anti-process. We're anti-process that doesn't help deliver the project.
Complex programs may need project managers, analysts, QA engineers, DevOps specialists and larger delivery teams. Smaller projects often don't.
We add roles when the project needs them — not because an agency structure requires them.
That's fine too. We can work independently or alongside your internal engineering team, CTO, product team, existing outsourcing partner, or larger delivery organization.
If your project requires a larger structure, we'll work within it. But when it doesn't —
You shouldn't have to pay for layers you don't need.
No proprietary platform required to keep working with us.

You don't need a finished specification. Give us whatever you currently have.
We'll review it and get back to you personally. For most projects, you'll receive our first technical direction and ballpark timeline and budget within 2 business days.
