Developers often need to run complex automation scripts but are limited by single-language tools. They waste time rewriting scripts or maintaining multiple runners.
Build a command runner that supports multiple languages (Scheme, Python, etc.) with easy extension points. Focus on interoperability between languages.
Polyglot development teams would adopt this to standardize their tooling. Could be sold to enterprises with mixed codebases.
Start with Scheme and one other language support. Add more later via plugins.
The biggest risk is competing with established task runners in each language ecosystem.
