Built by Engineers Who Understand the Stakes
We didn't set out to build another AI tool. We set out to solve one of the most consequential technology problems of our generation — the silent crisis of aging COBOL infrastructure holding the global economy hostage.
Born from Frustration with the Status Quo
TranspilerAI was founded after witnessing firsthand the catastrophic failures of traditional modernization approaches — multi-year consulting engagements that delivered incomplete migrations, introduced subtle logic errors, and left enterprises worse off than before.
The problem wasn't the engineers. It was the approach. Manual translation of COBOL to modern languages is error-prone, expensive, and impossibly slow at scale. The world needed a fundamentally different solution — one that combined the precision of formal methods with the power of modern AI.
That's what TranspilerAI is. A deterministic, semantics-preserving transformation engine that doesn't approximate your business logic — it preserves it exactly, with full traceability from every Python statement back to its COBOL source.
Liberate the World's Critical Infrastructure
To enable every enterprise running mission-critical COBOL to modernize with confidence — preserving decades of embedded business logic while unlocking the agility, talent, and economics of modern Python.
Correctness First
We never sacrifice accuracy for speed. Every transformation is verified to preserve the exact semantics of the original COBOL.
Enterprise Trust
We build for the most demanding environments on earth — banking regulators, government agencies, and Fortune 500 operations teams.
Radical Transparency
Full traceability from Python back to COBOL. No black boxes. Every decision is auditable and explainable.
Customer Outcomes
We measure success by whether our customers successfully modernize — not by lines of code processed or hours billed.

Frank Sledge brings over two decades of experience at the intersection of enterprise software, mainframe systems, and applied AI. Before founding TranspilerAI, Frank led modernization initiatives at several of the world's largest financial institutions, where he saw firsthand the scale of the COBOL crisis and the inadequacy of existing solutions.
His deep expertise in both legacy mainframe architecture and modern AI systems uniquely positioned him to design TranspilerAI's core engine — a hybrid approach that combines deterministic formal methods with AI-assisted programming to achieve what neither approach can accomplish alone.
Frank is a recognized voice in the enterprise modernization community, advising Fortune 500 technology leaders and government CIOs on legacy transformation strategy. He holds advanced degrees in Computer Science and has published research on semantics-preserving program transformation.
