# Genyra > Genyra is a software manufacturer and technology engineering company. It designs original native applications (the RIFT software family, in development), engineers enterprise software, investigates and modernises legacy systems, and builds and operates infrastructure, networking, telecommunications, hosting, web and mobile platforms. Custom AI is contracted through Genyra L.L.C-FZ, Dubai. Industries such as finance, legal and healthcare are customers, not the boundary of the practice. Genyra LLC is a Delaware limited liability company. Public contact: contact@genyra.com. Genyra LLC (Delaware) contracts software, infrastructure, web, telecommunications and networking work. Custom AI engagements are contracted with Genyra L.L.C-FZ in Dubai, which operates Genyra.ai; this site describes that practice too. Genyra is not a hosting or domain reseller: it designs and operates the platform and address space it hosts on. Current development initiatives are labelled by their actual status. Interactive engineering studies use synthetic examples; they are not customer case studies or released-product claims. ## Start here - [Genyra](https://genyra.com/): Software, systems, infrastructure and engineering exploration. -
