Renovix is an AI engineering team that migrates COBOL, Java EE, .NET Framework, Oracle Forms, and mainframe RPG to modern stacks — with shadow-execution verification on every line.
Trusted by modernization leaders at
Banks, insurers, and governments depend on code written in the 1970s and 80s. The engineers who wrote it are retiring. The consultancies who maintain it charge enterprise-grade fees for clerical work. And the rewrites your board has been promising for a decade keep slipping another year.
Renovix replaces the rewrite with an AI engineering team that ingests your codebase, understands the business logic, and ships a modern equivalent — verified line-by-line.
Each engine is tuned to the syntax, runtime, and idiom of a specific legacy stack — and shares one verifier, one audit trail, and one human-in-the-loop UI.
Every migration follows the same disciplined loop. The verifier never gets skipped.
Full source, runtime traces, schemas, and SME interviews are loaded into a private workspace.
Agents reverse-engineer the business logic and produce a structured spec your team can audit.
Modern code is produced with full test coverage, written to your style guide and stack choices.
Shadow execution runs old and new in parallel against production traffic and flags every diff.
Gradual traffic shift with instant rollback. Renovix owns the runway until you sign off.
Renovix doesn't just translate syntax. It captures the implicit business rules embedded in every IF, PERFORM, and EVALUATE statement — and produces idiomatic modern code that your team can actually read and maintain.
Every output is annotated with a citation back to the source line, so engineers and auditors can trace any decision to its origin.
* COBOL — premium calculation, 1982 IF POLICY-TYPE = 'A' COMPUTE PREMIUM = BASE * 1.15 ELSE IF POLICY-TYPE = 'B' COMPUTE PREMIUM = BASE * 1.25 END-IF. // TypeScript — Renovix output export function calculatePremium( policy: Policy, base: number ): number { const multiplier = MULTIPLIERS[policy.type]; return base * multiplier; }
Foundation models can read COBOL. They cannot ship a migration. Renovix is the agent-native system of record and system of action built specifically for modernization workloads.
Frontier models fine-tuned on millions of lines of COBOL, PL/I, RPG, and Java EE — with continual learning from every customer migration.
Our parallel-execution diff engine runs old and new code against the same traffic and flags semantic drift before it reaches production.
Every agent step, tool call, and code change is captured immutably — designed from day one for regulators, not retrofitted later.
Subject-matter experts approve decisions where it matters. The system never confuses confidence with correctness.
Every workflow run produces labeled supervised data that improves the next migration — a moat that strengthens monthly.
SOC 2, SSO/SCIM, RBAC, audit log, VPC deployment, BYOK encryption — table stakes, shipped.
"We had been quoted $34M and four years to retire our COBOL claims engine. Renovix delivered in eleven months for a fraction of the cost — and the new system is the first one our engineers actually want to work on."
We will analyze a representative subsystem of your codebase and return a fixed-scope, fixed-price migration plan in two weeks.
