Enterprise-grade product simulation and demo automation platform powered by AI agents for supercharging go-to-market motions.
Demostack is a Sales & Marketing product simulation platform that helps enterprise software companies build high-fidelity, AI-powered demo environments to shorten sales cycles and scale GTM operations, with pricing available on an enterprise-only basis via custom quote. It primarily serves solutions engineers, sales leaders, product marketers, and L&D teams at mid-market and enterprise SaaS organizations that need repeatable, safe, and personalized demo experiences.
Founded in 2020 and headquartered in Tel Aviv and New York, Demostack has grown into one of the most recognized names in the demo automation space, serving notable customers including Intercom, Wix, WalkMe, Gainsight, BlueVoyant, Hunters, Motive, Hopin, and Yotpo. The platform's flagship capability is the Demostack Cloner, which captures a user's ideal demo flow inside a live application and instantly generates a safe, fully functional replica that sellers can deliver repeatedly without touching production. On top of this foundation, Demostack layers a suite of AI Agents — including the AI Simulation Builder Agent, AI Database Bulk Category Editing, AI Text and Image Generator, and AI for Data Rules — that let users edit simulations through natural language prompts rather than manual code or staging work. Reported customer outcomes include Gainsight increasing its win rate by 25%, Hunters cutting its sales cycle in half, and BlueVoyant securing a multi-million dollar RFP on the strength of a single Demostack-powered demo.
Based on our analysis of 870+ AI tools, Demostack sits at the enterprise end of the demo automation category alongside competitors like Walnut, Reprise, Navattic, Consensus, and Storylane. Compared to lighter-weight interactive demo tools that focus on marketing-site product tours, Demostack differentiates by offering a full product simulation layer — including editable backend data, data rules, and database bulk edits — making it better suited for complex B2B SaaS platforms with deep functionality. It is recognized as a Leader on the G2 Presales Grid Report, reflecting strong traction with solutions engineering and presales teams who need more than a click-through tour. Buyers evaluating Demostack should expect an enterprise procurement process, a quoted pricing model rather than self-serve plans, and the trade-off of richer simulation capabilities in exchange for a heavier implementation lift than simpler alternatives.

The Cloner records a user's click-through of their live application and instantly produces a safe, fully functional replica that sellers can reuse. This eliminates the 'Groundhog Day' of manually rebuilding demo environments and removes any risk of exposing real customer data. It is the foundational capability on which all other Demostack simulations and AI edits are built.
The AI Simulation Builder lets users edit multiple parameters across a simulation using plain-English commands, such as adjusting dashboards, charts, or layouts. It removes the need to learn a proprietary editor or involve engineering for cosmetic and structural changes. This makes it practical for non-technical AEs and product marketers to personalize demos at scale.
This agent automates edits to entire datasets inside a simulation, so demo owners no longer have to update records one by one for each prospect vertical or use case. It is particularly valuable for data-heavy products like analytics, security, and CRM platforms where realistic data is essential. Customers like WalkMe cite this type of capability as a 'total game changer' for data-driven storytelling.
AI for Data Rules lets teams modify application logic and technical states through natural language instead of manual code overrides. This means conditional behaviors, workflows, and rule-based features can be tuned per demo without a developer in the loop. It blurs the line between a static simulation and a live product, which is why Demostack positions itself as a 'product simulation layer' rather than an interactive tour.
Demostack transforms the so-called 'dark funnel' by correlating granular demo engagement with GTM team motions and revenue outcomes. Revenue leaders can see which scenarios resonate, where prospects drop off, and which reps are driving results. These insights feed directly into coaching, playbook design, and GTM resource allocation.
