Who uses Cosine?

Cosine is used by engineering teams across industries — from startups to global enterprises in finance, defence, and technology. It’s trusted by organisations with the highest standards for security, scalability, and code quality.


Investment banks and fintech companies use Cosine to modernise legacy systems, automate maintenance, and accelerate delivery. Cosine runs in fully private or air‑gapped environments, meeting strict regulatory and data‑sovereignty requirements.

Defence contractors and government agencies deploy Cosine on‑premise for complete control over their infrastructure. Cosine assists with refactoring, documentation, and large‑scale modernisation of secure codebases.

SaaS providers and hyperscalers integrate Cosine to boost developer velocity — clearing backlogs, maintaining microservices, and improving test coverage.

Industrial software teams use Cosine for maintaining code written in specialized languages like Fortran and VHDL, enabling modernisation without rewriting from scratch.
