## About
Ifdef got its start when a few Tokyo engineers grew tired of feature flags and preprocessor directives turning their codebases into a tangled mess. They started with some quick internal scripts to pull things together and ended up building a full platform around it. The tool gives teams one place to define, test, and roll out conditional logic without forcing anyone to change their editor or build setup. It slots right between the editor and the pipeline so developers keep working the way they always have. Mid-sized engineering groups at Japanese manufacturers, fintech startups, and game studios use it to handle platform differences and staged releases. Most teams notice fewer merge conflicts and quicker code reviews after switching. The founders still code every week and keep the whole interface straightforward so new people get up to speed fast. Customers are mostly in Japan with a few Southeast Asian teams on the hosted version. Revenue comes from annual subscriptions and the occasional CI integration project. The company stays bootstrapped with a small team to move quickly. Updates drop every three weeks based on what users actually say they need. Support comes straight from the engineers who built it, no sales team in the middle. Word of mouth in the Japanese developer scene brings in most new business. The Shibuya office also hosts casual talks on build
