Cosairus

Cosairus is a custom software development company that places its engineers inside a client's team to improve the systems the business already runs. Rather than rebuilding from scratch, it uses AI-assisted development to add tests, document code and lower the risk of each release.

What Cosairus offers

• Embedded modernisation engineering — working within an existing codebase to extend and stabilise legacy software.
• AI integration — spotting practical uses for AI and building features and models into day-to-day workflows.
• Web and mobile applications — browser platforms and native or hybrid iOS and Android apps.
• System integrations — linking internal platforms with CRMs, ERPs, payment processors and other third-party services.
• Databases and reporting — database design and tuning, data warehouses, dashboards and reporting pipelines.
• Workflow automation — replacing spreadsheets and manual handoffs with purpose-built applications.
