Demo day investors, accelerator partners
Data rooms for accelerators and demo day
Demo day compresses a raise into a few weeks. The founders who have their room ready before they walk on stage take the meetings that matter.
An accelerator batch raises at the same time, in front of the same investors. After the pitch, inbound interest arrives in days, and many investors decide within a week. Most rounds are SAFEs, so the documents are light but must be instant.
Accelerators themselves also use rooms: to share batch materials with their investor network and to collect portfolio documents for their own reporting.
What matters most: Volume in a short window: per-investor tracking and fast follow-up decide who you call first.
