Ask HN: What usually happens after a VC asks for a demo?

I had a VC call that went well. They asked for a demo, mentioned looping in an operating partner, and I shared details etc. Since then it’s been quiet (a day or two).

For folks who’ve raised before or worked in VC: Is this typically just internal review time, or does silence after a demo usually signal a pass?

Not looking for validation, just trying to understand how this phase usually plays out.

Thanks.
