Legacy systems you can't understand, can't safely change, can't confidently migrate.

On-Premise ReadyCOBOL / Java / ERPAI + Human-in-the-Loop20+ Enterprise Projects

Do any of these sound familiar?

Nobody truly understands what's inside the system
No specs exist — every change feels risky
Impact scope is unclear with every modification
We want to modernize, but lack the time and people

FARE, NEXA, and SYNCA solve all of these together.

FARE

AI Reverse Engineering

Step 1: Understand — Reverse-engineer the spec that was never written

SYNCA

AI Quality & Change Impact

Step 2: Control — Know what breaks before you touch anything

NEXA

AI Engineering Automation

Step 3: Build — Generate modern code from your spec

OUR SOLUTIONS

FABBI Solutions

Fabbi is a technology company that supports the analysis, evolution, and reconstruction of enterprise systems using generative AI at its core.

FARE

Fabbi AI Reverse Engineering

FARE reconstructs design documents, architecture diagrams, and business logic from running source code. COBOL, Java, PL/SQL, and 10+ languages. 60% less analysis effort. Delivers a foundation that makes every subsequent change safe.

SYNCA

AI Quality & Change Impact Analyzer

SYNCA traces dependency chains across 200K+ lines and identifies the full impact scope before any change reaches production. 90% impact accuracy, 5× faster than manual analysis. Prevents the regression failures that derail enterprise release cycles.

NEXA

Next-gen AI Engineering Automation

NEXA generates production-ready code, tests, and documentation from design specifications. 70–80% first-pass accuracy means your engineers complete business logic, not boilerplate. Works with your SIer team — not instead of them.

OPERATING MODEL

AI + Human-in-the-Loop. Controlled Delivery.

Fabbi does not replace your engineers or your SIer. AI handles what takes humans 60–90% of their time. Humans validate what matters.

AI (FARE / SYNCA / NEXA)

Responsible for

Analyze code structure and dependencies
Generate design documents and architecture diagrams
Detect change impact scope
Generate code scaffolds and test stubs

NOT responsible for

Replace business decisions
Make architecture choices autonomously
Deploy to production without approval

SIer / Delivery Engineer

Responsible for

Review and validate AI analysis output
Customize generated code for business logic
Sign off on architecture decisions
Coordinate delivery with client team

NOT responsible for

Run manual documentation from scratch
Perform dependency tracing manually
Accept AI output without review

Client Business Team

Responsible for

Validate business rules and logic
Approve migration decisions and milestones
Sign off on final deliverables

NOT responsible for

Review code implementation details
Manage AI analysis configuration
Handle technical infrastructure

Nothing ships without human sign-off. AI accelerates the work; your team approves the outcome.

ABOUT US

About Fabbi

We provide AI solutions that are practical in real-world settings — addressing challenges such as black-boxing due to insufficient documentation, opacity of impact scope during changes, and balancing development speed with quality.

Fabbi's solutions cover the system lifecycle across three phases. This enables maximizing ROI and development productivity while minimizing risk.
