Stop Treating Diagrams as Docs — Make Class Diagrams Executable

Design and interview diagrams are static debt. Convert class diagrams into executable, testable models that run, validate, and generate scaffolding so design reviews and SDE-2 prep become deterministic and code-aligned.

Target Audience

Engineering managers, interview prep instructors, mid-level engineers preparing for system-design interviews (SDE-2 to Senior IC), and small engineering teams building documented, executable designs.

Key Pain Points

Standards fragmentation -- multiple modeling syntaxes (UML, C4, custom DSLs) fragment adoption and increase integration cost.
Open-source substitution -- free text-to-diagram tools and traditional diagramming apps reduce willingness to pay for premium features.
Overtrust & correctness -- executable models that are incorrect could create false confidence; high QA bar needed to avoid liability.

Market Opportunity

Stop Treating Diagrams as Docs — Make Class Diagrams Executable targets a $10.0B = 1,000,000 engineering orgs x $10K ACV (company-wide design/runtime-spec tooling) total addressable market with medium saturation and a year-over-year growth rate of 15-25% growth driven by dev-tools, MDE and AI-assisted engineering adoption.

Key trends driving demand: AI-code-synthesis -- LLMs make converting specs to runnable code and tests much faster, enabling executable diagrams.; Shift-left validation -- teams adopt testing/specs earlier, increasing demand for executable design artifacts that can be validated pre-implementation.; Infrastructure-as-code norms -- executable specifications are accepted practice for infra and increasingly for application architecture.; Remote interviewing & hiring -- reproducible, runnable interview artifacts improve assessment quality and reduce bias..
