Training and Onboarding for Legacy Enterprise Systems

Banks, airlines, insurance and gov still run 40-year-old legacy software where refactoring is impossible, making onboarding enterprise customers and training employees extremely difficult without specialized tools.

Software that teaches people how to use unmaintainable 40-year-old systems that can't be replaced.

The pain

Banks, airlines, insurance companies, and government agencies run mission-critical software written in COBOL or similar languages. These systems handle trillions in transactions annually. Replacing them costs hundreds of millions and takes years. When new employees or customers need to use these systems, there's no modern UI, no intuitive workflows, and documentation is either nonexistent or outdated. Training takes months. Mistakes are expensive. Turnover means constant retraining.

The gap

No tool exists that bridges the gap between legacy system complexity and human usability. You can't refactor the backend. You can't change the interface. But you can create an intelligent overlay, interactive guides, contextual help, automated workflows, or AI-assisted navigation that makes the system learnable without touching the underlying code.

Build angle

Start with one vertical (banking operations, airline crew scheduling, insurance claims processing) and one specific workflow. Build a tool that sits on top of the legacy system, screen recording + AI pattern recognition + interactive tutorials. Measure success by time-to-productivity for new hires and error reduction. Charge per user per month or per training completion. Expand to other workflows and verticals once you have proof.

Strengths

  • Massive TAM: Every Fortune 500 bank, airline, and insurance company has this problem. Government agencies multiply it further.
  • High switching costs: Once embedded in onboarding, replacing it means retraining everyone again.
  • Recurring revenue: Training happens continuously as employees turn over.
  • Defensible: Requires deep domain knowledge of specific legacy systems to build effectively.
  • Urgent problem: Companies lose money every day from slow onboarding and user errors.

Risks

  • Sales cycle is long and complex: You're selling to large enterprises with procurement processes that take 6-12 months.
  • Integration complexity: Each legacy system is unique. Building for one bank's mainframe doesn't transfer to another's.
  • Regulatory friction: Financial and government sectors have strict approval processes for new tools touching sensitive systems.
  • Unclear willingness to pay: Companies may see this as a training problem, not a software problem. Budget may come from HR, not IT.
  • Competitive threat from low-tech alternatives: Some companies may just hire more trainers or accept higher turnover rather than buy software.
  • Proof of concept is hard: You need access to actual legacy systems to build and test, which requires customer partnerships before you have a product.
