As software systems grow more complex and AI accelerates code creation, engineering organizations are overwhelmed by manual processes, fragmented tools, and brittle workflows. Productivity tools help individuals move faster, but the SDLC itself remains slow, reactive, and human-bound. Overcut transforms the software development lifecycle into a system of agentic workflows that operate directly inside Git and Jira. Instead of assisting developers step by step, Overcut executes end-to-end engineering processes such as triage, analysis, review, remediation, and delivery with built-in control, context, and accountability. The result is a new model for building software. Continuous execution instead of manual coordination. Organizational automation instead of individual assistance. A future where engineering teams scale quality, speed, and trust together.
