Satispay

Claude Code deployment across engineering

Satispay upgraded its core payment service in under 4 days against a 4-week estimate

WorkingVendor case studyVendor ↗

Problem

Satispay's earlier-career engineers spent substantial time understanding unfamiliar Java and Spring services. Senior review became a bottleneck because reviewers also had to teach and explain system context.

Approach

Satispay evaluated Claude Code on real development tickets in mid-2025 and deployed it through managed engineering laptops. Engineers used it to change code and review work before human review. They retained responsibility for merged code.

Results

under 4 daysJava and Spring modernization of the core transaction service against a 4-week estimate, per AnthropicVendor case study[1]
75%+monthly committed code generated with Claude, per AnthropicVendor case study[1]

Takeaway

The payment-service result compared elapsed work with an initial estimate. It did not establish the speedup against a measured manual implementation.
