Executive Summary

Many frontend libraries and framework bundles ship only compiled JavaScript and either omit or ship low-quality TypeScript declaration files, creating friction for library authors, downstream integrators, monorepo maintainers and enterprise teams who rely on accurate types for safety and productivity. This gap forces manual declaration maintenance, brittle ad-hoc typings in consuming projects, and friction during upgrades — problems felt across the 26 million software developers who collectively represent a $10.4B developer tools market. You could build a toolchain and hosted service that preserves or generates sound .d.ts artifacts at distribution time: a build-plugin and CLI that is bundler-aware (Vite/Rollup/webpack), a CI/GitHub Action that enforces declaration fidelity, and an optional hosted registry transform that augments packages before publishing. The core would combine static analysis, source-map-aware mapping and AI-assisted inference to handle missing source or lost type metadata, paired with an enterprise audit trail and integration points for registries and IDEs; monetization paths include per-repo subscriptions, enterprise licensing and a freemium open-source tier. The timing looks favorable: TypeScript adoption continues to rise and many modern frameworks still distribute compiled JS without reliable types, while improvements in code models and LLMs materially increase the feasibility of automated declaration generation. With a Market Score of 92/100 and Revenue Potential at 82/100, there is clear commercial opportunity if you can convert developer trust into paying customers. To stand out you should prioritize correctness guarantees, reproducible builds and deep integrations (CI, registries, IDEs), plus a human-in-the-loop workflow for edge cases—these are defensible differentiators versus existing medium-competition tools. Be honest about the hard engineering problems ahead: inference limits, bundler diversity, legal/licensing provenance and the challenge of convincing open-source projects to adopt a paid layer; start with enterprise CI and registry integrations to capture early revenue while iterating the open-source developer experience.
