About
Demostack is a demo automation platform that enables sales engineers and account executives to create fully interactive, data-customized product demos without requiring engineering support. The platform works by cloning the production application into a sandboxed demo environment that looks and behaves exactly like the real product but runs on synthetic data that can be tailored for each prospect. Sales teams can swap in a prospect's logo, industry metrics, and relevant use case data to create a highly personalized demo experience without touching a live system or waiting for engineering to provision a demo tenant.
