LedgerLegacy vs. Modernized
Stack Metrics
Every row below is drawn from a live client engagement. Numbers are contractually verified and available under NDA for qualified prospects.
| Metric | Legacy Stack | Ledger-Modernized | Improvement |
|---|---|---|---|
| Trade Settlement Time | 2–3 Business Days | < 800ms | 87% faster |
| Peak Transaction Throughput | 4,200 TPS | 380,000 TPS | 90× capacity |
| API Integration Endpoints | 12 proprietary | 340 REST/gRPC | 28× ecosystem reach |
| System Downtime (Annual) | 47 hours | < 2 hours | 96% availability gain |
| Deployment Cycle | 6–9 months | 2-week sprints | Continuous delivery |
All figures represent median outcomes across comparable engagements. Individual results vary by environment complexity.
Who We Work With
Three distinct client profiles. One methodology. Infrastructure that stops being a liability and starts being a competitive moat.
Mid-Market Banks
Your COBOL core processes $12B/day and your engineers are afraid to touch it.
- Core banking platform end-of-life in 18–36 months
- Regulatory mandates requiring real-time reporting
- Inability to onboard modern payment rails (ISO 20022, FedNow)
Insurance Carriers
Manual reconciliation is eating 11,000 analyst hours per year.
- NAIC / Solvency II audit preparation taking 6+ months
- Policy administration systems unable to support new products
- Reconciliation exceptions processed manually overnight
Growth Fintechs
Your Series A architecture won't survive Series C due diligence.
- Monolith can't support 50× transaction volume growth
- Investor technical due diligence exposing architectural debt
- Compliance gaps blocking banking-as-a-service partnerships
Compliance, Cost &
Integration Benchmarks
The operational burden of legacy infrastructure doesn't appear on a balance sheet until it's too late. These numbers do.
in annual maintenance cost
| Operational Metric | Legacy Environment | Post-Modernization | Delta |
|---|---|---|---|
| Compliance Audit Preparation | 5–7 months | 3–4 weeks | 85% time reduction |
| Manual Reconciliation Exceptions | 11,200 / month | < 40 / month | 99.6% automation rate |
| Integration Endpoints (External) | 8 proprietary connectors | 312 open APIs | 39× ecosystem connectivity |
| Annual Infrastructure Maintenance | $4.2M / year | $610K / year | 85% cost reduction |
| Regulatory Reporting Cycle | T+5 manual | T+0 automated | Real-time compliance |
| New Product Time-to-Market | 14–22 months | 6–10 weeks | 8× faster launch |
Figures represent verified client outcomes. Full methodology available upon NDA execution.
