Demostack vs. Karumi

Demostack is the product simulation layer for enterprise software. We create high-fidelity, scalable, and shareable clones of complex software products - so sales can demo, buyers can experience, enablement can train, L&D can certify, and partners can learn, all without touching expensive and fragile production environments. Enterprise software companies use Demostack to eliminate the gap between product development and market impact.

Karumi is an AI-powered product expert that joins your video calls and helps teams deliver clear, consistent product demos without extra prep work. Instead of relying on scripted walkthroughs or pre-recorded videos, Karumi can run a live, agentic demo of your product, adapt to what the customer wants to see, and answer questions in real time. It behaves like a knowledgeable teammate who always knows how the product works and can guide people through the experience step by step.
