Your legacy code,
rebuilt for the AI era.
We use AI to convert COBOL, PowerBuilder, Delphi, legacy .NET and other aging systems into modern, maintainable, cloud-ready software — and we test hand in hand with you to ensure every module behaves exactly as your business requires before it goes live.

What we do
End-to-end modernization, guided by AI and verified by engineers.
Code Conversion
Automated translation from COBOL, PowerBuilder, Delphi, VB6 and legacy .NET into modern languages and frameworks.
Logic Preservation
Every business rule is extracted, documented, and verified so nothing is lost in the cutover.
Test Generation & Sign-Off
Together we build an automated regression suite — from characterization tests that capture your legacy behavior to full end-to-end UI tests (Playwright) that exercise the whole system. Your team reviews and approves every rule, so the new build meets your standard, not just ours.
Cloud Re-platforming
Move from the mainframe and aging desktops to scalable, secure cloud infrastructure.
Database Migration
Modernize VSAM, IMS, Oracle and SQL Server into PostgreSQL and other clean, well-structured stores — often eliminating database license fees along the way.
Ongoing Evolution
Conversion is just the start. We keep modifying, extending and future-proofing your modernized system so it evolves with your business — well into the future.
Not tied to one target language
Traditional migration tools lock you into whatever stack they were built to emit. Our approach is AI-driven — it works at the level of your business logic and re-expresses it with equal fluency in whichever modern language fits your team. You choose the destination; we're not selling you ours.
.NET 10 / C#
Enterprise-grade and easy to hire for — and modern .NET runs natively on Linux, so you keep the ecosystem without Windows licensing.
PHP / Laravel
A pragmatic, low-cost target for line-of-business web systems your team — or your MSP — can maintain in-house.
Python
Ideal where the modernized system leans on data processing, integrations, scripting, or ML-adjacent workloads.
C++
For performance-critical, high-throughput workloads where every millisecond and every byte counts.
These are common targets, not a fixed menu. The free assessment recommends the best-fit stack for your systems and your team — not a house preference.
Modern code is only half the savings
Most legacy systems bleed cash on Oracle, SQL Server and Windows Server licensing — every year, whether the capacity is used or not. We're equally at home moving you to PostgreSQL and Linux, so the same workload runs on enterprise-grade, open-source infrastructure with no per-core license to renew. And because modern .NET, PHP and Python all run natively on Linux, even a C# modernization sheds its Windows licensing. Modernization becomes an operating-cost cut, not just a tech-debt cleanup.
- PostgreSQL in place of Oracle / SQL Server — Enterprise features, zero database license fees.
- Linux in place of Windows Server — No CALs, no per-core Datacenter licensing.
- Better performance-per-dollar — A leaner, cloud-friendly footprint that scales without a licensing penalty.
How a migration works
A predictable, low-risk path from legacy to modern.
Assess together
A fixed-price, 2–4 week engagement: working side by side with your team, we map dependencies, document your business rules, and deliver a modernization plan you own. The deliverables are yours to keep — whatever you decide next.
Convert
Our AI pipeline translates the code module by module while a senior architect reviews every critical path.
Verify together
Tests generated from your legacy system's actual behavior prove the new system matches — quirks included. Your team reviews the diff report and signs off before anything goes live. Not a promise — a shared standard.
Cut over — together
Module by module, with your team in the room. The old system stays live until you and we agree each piece has proven parity. Then documentation, knowledge transfer, and ongoing support.
We verify together — before a line is converted
Before any code is converted, we sit down with your team to extract, document, and sign off every business rule in plain English. Then we generate tests from your legacy system's actual behavior. Your team approves the rules. Our code has to pass the tests. Here's what that looks like on a real VB6 billing routine.
Public Function CalcLateFee(InvAmt As Currency, _
DaysLate As Integer) As Currency
Dim Fee As Currency
If DaysLate <= 0 Then
CalcLateFee = 0
Exit Function
End If
Fee = InvAmt * 0.015
If DaysLate > 30 Then
Fee = Fee + (InvAmt * 0.005 * Int(DaysLate / 30))
End If
If Fee > InvAmt * 0.1 Then Fee = InvAmt * 0.1
CalcLateFee = Fee
End Function
public static decimal CalcLateFee(
decimal invoiceAmount, int daysLate)
{
if (daysLate <= 0) return 0m;
var fee = invoiceAmount * 0.015m;
if (daysLate > 30)
fee += invoiceAmount * 0.005m * (daysLate / 30);
var cap = invoiceAmount * 0.10m;
return Math.Min(fee, cap);
}
Your team owns the rules. We prove the code matches.
We extract every business rule from the legacy code and write it in plain English. Your subject-matter experts review, correct, and sign off each one before a single line of new code is written. No rule goes into the converted system that your team hasn't approved.
Late fee = 1.5% of the invoice, plus 0.5% for each full 30-day period overdue beyond the first 30 days, capped at 10% of the invoice. No fee if not overdue.

Proven on real projects
A few of the systems we've already modernized.
You keep the client. We handle the legacy.
MSPs, fractional CIOs, and dev agencies: when a client is stuck on a system nobody on your team wants to touch, send it to us — and get paid for it.
Referral
of assessment + project fees
Make an introduction — we sell and deliver, you collect commission as client payments clear. Zero effort beyond the intro.
Accelerator
volume-based commission
Co-sell with us: join the calls, own the relationship, help close. Higher effort, higher share — rates climb with each deal.
White-label
on top of wholesale pricing
We deliver under your brand and stay invisible to the end client. Your client sees one agency that can do anything.
No exclusivity, no quotas, 12-month deal registration protection — and a full partner kit to sell with.
