Ask HN: Do you have examples of data rooms for startup fundraising?

Hi HN!

I'm Israel, cofounder of Neuraan (https://neuraan.com), an API to build more accurate Natural Language Processing (NLP) applications in Spanish.

We're raising our pre-seed round and a VC just ask me for a data room, I don't have one so now I'm building one but I don't know how much info should I include on it and where should be: Docsend, Google Drive, Confluence, Notion?

Can you help me with some examples?
