Ask HN: How do you manage your demo env?

Hey all, we're in the process of scaling our sales org. Since we rely on demos we're exploring the best practices in managing demo environments. Our current thoughts are: - We can simply use production, but that seems risky - New features might surprise AEs in the demos, A/B tests, production data? data reset between demos - We could clone a branch of production and create a dedicated demo env, almost the same problems as above minus the features surprises. - We can simply use PowerPoint which solves most of the problems above but feels like we'll lose a lot of the wow factor of our app.

Any ideas? What are the current best practices to create/manage/update a demo environment? Share your wisdom guys!
