Autonomous agents that rewrite legacy code — end to end.
A swarm of specialized AI agents ingest, understand, rewrite, verify, and ship your legacy systems to modern stacks — with provable behavioral equivalence and zero rip-and-replace risk.
Legacy code is the silent tax on modern enterprise.
Every Fortune 500 runs on code older than its youngest engineer. Migrations are political, expensive, and fail more often than they ship. We built a platform that makes the math work.
Meet the Agent Swarm
Six specialized AI agents, each an expert in a single stage of modernization — orchestrated as a single autonomous pipeline.
Cartographer
Parses COBOL, ABAP, PL/SQL, VB6, and legacy Java into a unified AST graph — mapping every module, symbol, and data flow into a searchable knowledge base.
Semantic Reasoner
LLM-powered reasoning layer that extracts business rules from decades-old code, identifies dead branches, and writes human-readable specs for every workflow.
Transpiler Core
Rewrites legacy modules into idiomatic Python, TypeScript, or Go — applying clean architecture, type safety, and framework best-practices automatically.
Oracle
Generates equivalence tests, property-based fuzzers, and golden-record replays to prove the modernized code behaves identically to the original.
Choreographer
Untangles ERP integrations — SAP IDocs, Oracle EBS, Salesforce APEX — and replaces tight coupling with event-driven microservices and typed contracts.
Shipwright
Containerizes, benchmarks, and ships to Kubernetes with feature flags and canary rollouts — blue/green by default, instant rollback if metrics drift.
The Pipeline
Six stages, fully automated — from legacy repo to canary-deployed microservice.
Ingest
Git, SVN, mainframe dumps, or tarballs — we index it all.
Map
Build a living graph of modules, symbols, and data.
Reason
LLMs extract business rules and generate specs.
Rewrite
Generate clean, typed, idiomatic target code.
Verify
Differential tests prove behavioral equivalence.
Ship
Canary deploy with instant rollback.
From Anything, to Anything
Bring us the ugliest corner of your stack. We speak legacy and modern fluently.
What We Guarantee
The four commitments that make autonomous modernization safe for production-critical systems.
Behavioral Equivalence
Every rewritten function ships with a diff-test proving identical output on 10k+ real production inputs.
10× Throughput
Agents parallelize across modules — a 2M LOC COBOL codebase maps and rewrites in under 72 hours.
Zero Lock-In
Output is plain, idiomatic code in your target stack. No runtime, no SDK, no QuantCore dependency.
Incremental Cutover
Strangler-fig deployment — run old and new side-by-side, route traffic gradually, rollback in one click.
Real Systems, Real Cutovers
A sample of what the pipeline has shipped — every migration measured against production.
SAP ABAP → Python Microservices
Decompose 800k LOC of Z-reports and custom BAPIs into event-driven Python services behind a GraphQL gateway. SAP stays as the system of record.
COBOL Mainframe → Cloud-Native Go
A regional bank's core batch processing moved off z/OS onto AWS ECS — preserving every business rule through differential replay against 3 years of golden records.
.NET Framework → TypeScript + Next.js
A manufacturer's aging intranet of 40+ ASP.NET WebForms apps rebuilt as a unified Next.js platform with typed contracts and edge-deployed APIs.
Bring us 100k lines. We'll ship a proof.
Send us a representative slice of your legacy codebase. We'll return a fully rewritten, tested, and deployed service inside two weeks — no commitment, no invoice.
