• Start time: Timer begins after repository access + kickoff call
• “Not valuable”: Client rejects within 5 days of delivery with 3-sentence explanation
• Timeframe source: Internal estimates show analysis typically takes 1-2 days
• Bring your dev: Your developers are welcome to participate in all sessions
Code Migrations Are
Expensive & Risky
Traditional code migrations drain resources, introduce risks, and block innovation for months.
Legacy consumes resources & time
70% of all enterprise applications are older than 20 years and tie up 70% of total IT capacity. This prevents innovation and paralyzes strategic projects.

Legacy systems deter top talent
47.5% of senior developers consider changing jobs due to outdated technologies. 27.5% cite legacy maintenance as the main frustration factor in daily development.
Source: TechRadar
Innovation and releases are delayed
Technical debt consumes up to 50% of IT budgets annually, delays releases by up to 6 months, and massively increases opportunity costs.

Legacy increases risk of cyber incidents
82% of codebases use outdated libraries; 75% contain known vulnerabilities. These cause 32% of all attacks and 60% of severe operational disruptions.
Source: TechTarget 2025
Outdated systems create massive additional costs
Outdated software costs $2.41 trillion annually and wastes up to 33% of developer time. In insurance, costs per policy increase by 41% due to legacy systems.
