Who We Are

-------------------------------------------------------

Our objective is to change the way programmers and AI tools integrate software components and distributed services by leveraging our worldwide unique technology. It enables seamless integration across cloud-based distributed services, across programming languages, and allows systems to switch between monolithic and microservices architectures without rewriting integration logic.

We have recently released an alpha version of the product. Our current focus is on stabilizing the core platform, improving reliability, and completing the web portals. At the same time, we are refining a service that allows programmers and AI tools using any technology to access and reuse logic from modules written in any language, whether locally within a single application or remotely in a cloud microservices environment - without writing any integration layer. Developers simply call the methods they need, as if the required classes were written in their own technology and available in the same application.
