A clear picture of what's holding you back
A structured two-week diagnostic of your architecture, data flows, and dependencies. You get a clear view of the risks, bottlenecks, and a prioritized plan to move forward.
You need this when
Features take months instead of days
Your architecture makes even small changes expensive and risky.
You're afraid to touch critical parts of the system
No one fully understands the dependencies or what will break.
AI initiatives keep stalling
Your data structure and architecture can't support real AI deployment.
Technical debt is slowing every team
Engineering time goes to managing complexity, not building product.
You don't know where to start
There are too many problems and no clear prioritization or path forward.
What you get
Architecture Map
A full picture of your current system — services, dependencies, data flows, and integration points.
Triage Board
A prioritized view of what to keep, change, and replace — organized by risk and impact.
Phase Timeline
A phased modernization plan with estimated timelines, resources, and milestones.
Risk Gauge
A clear assessment of the technical, operational, and business risks in your current system.
Service Stack
A detailed breakdown of each service — its role, health, and modernization priority.
How it works
Kickoff
We align on goals, scope, and access requirements. We meet your team and establish the diagnostic framework.
Diagnostic
We analyze your architecture, codebase, data flows, and dependencies. We identify bottlenecks, risks, and opportunities.
Decision
We present our findings and recommendations. We work together to validate priorities and shape the modernization plan.
Hand-off
You receive a complete modernization roadmap with clear next steps, whether you work with us or execute independently.
Results speak for themselves
We've modernized over 80 systems and products, helping teams move faster and making them ready for the next era of technology.

“Our system was holding back internal operations and product development. Eli5 modernized the foundation, simplifying complexity and enabling us to move faster with far less friction.”
Bart Zirschky
