What CloudGeometry does Most companies run on software they've built and depend on every day. Keeping that software working, fixing bugs, staying patched, and adding new features normally means hiring and managing a team of developers. That's expensive, slow to scale, and hard to keep staffed....

As answered by people managing CloudGeometry AI MSL and Diffyn.
CloudGeometry AI MSL's answer
Most AI coding tools make individual developers faster. AI-MSL runs the whole job as a service: it builds, fixes, and modernizes your existing software, with AI doing the work and real engineers reviewing and approving every change before it ships. It starts by mapping your entire codebase (AppGraph), so changes are made with full knowledge of how your system actually works, and you keep complete ownership of your code.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
CloudGeometry AI MSL's answer
Accountability. Autonomous coding agents hand you code and leave the risk with you. With AI-MSL, a named senior engineer stays accountable for your system, every change passes human approval gates (requirements, specs, code, QA), and there's a full audit trail of what changed, why, and who approved it. You get the speed of AI development without giving up control, quality, or ownership.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.

CloudGeometry AI MSL's answer
Companies that run on custom software and need to keep improving it, business and technology leaders who have real production systems, a backlog they can't get through, and no appetite for building or scaling a large in-house development team. It's built for existing, working software rather than brand-new projects.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
CloudGeometry AI MSL's answer
AI-MSL was built by CloudGeometry, a US engineering services company (AWS Advanced Consulting Partner, CNCF Kubernetes Certified Service Provider) that has spent years modernizing and running production systems for clients. When AI code generation became genuinely capable, the team saw the real gap wasn't writing code faster, it was everything around the code: review, testing, safety, accountability. So they built AI-MSL, a managed service where AI executes and experts supervise, and proved it by using it to build and maintain their own software.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
