Praxent recovers every business rule your legacy platform holds, then rebuilds in waves on AI-ready architecture while your business keeps running.


Your engineering team builds faster on a modern codebase, learning Claude Code and AI-native practices beside our forward-deployed fintech engineers.

Regression suites built from your recovered business rules let your QA team test and sign off on every financial calculation with zero variance.

Say yes to new products as your team plans new loan types, payment flows, and embedded finance offers on a platform built for the pace of change.

Keep daily processing on schedule with rollback ready at every migration stage, so your operations team plans new initiatives as each domain moves over.

Show examiners where every rule came from, tracing it from legacy source to the new code, so your compliance records stay accurate and audit-ready.

At a top-5 global payment processor, nearly $2B a day in payments reconciliation ran on a platform of undocumented Delphi code no one could compile, patch or rehost. Its builders had left, and an earlier modernization had stalled. PraxentDecode℠ reverse-engineered the full codebase, recovering core logic and dependencies, surfacing 5 security issues, and producing a complete platform map and a future modernization plan.

Every business rule, dependency, integration, and data model in your legacy code is recovered by our AI agents, then confirmed by your experts, so you own a verified record before any rebuild starts.
What it produces
We design your target-state architecture as cloud-native on Azure around the regulatory requirements financial services demands, so AI agents and modern experiences plug right in.
We build the platform, prove parity, and migrate in waves with legacy running side-by-side and rollback-ready. Development timelines are compressed 25–40% as value lands in weeks with no big cutover.
With all domains migrated and validated, we execute the production cutover and decommission your legacy systems. Your team fully owns the modern platform with the decoded specifications as documentation.
To deliver hyper-customized workflows, Praxent embeds Forward-Deployed Fintech Engineers (FDEs). These are certified experts who combine
AI-native engineers with hands-on experience around modern AI capabilities, governance, tokenomics, and rapid iteration to deliver results.
Specialists who deeply understand regulated financial operations, fraud, compliance, and core processing systems.
As legacy systems carry undocumented workflows or unclear rules, we review each one with your team, from loan servicing to payment settlement. You decide what to redesign, and your experts shape the platform.
