RoundOS Data Room's answer:
Codex & Claude are my main software developers. React, Tailwind, Node.js, Python, ClickHouse, Postgres — our tech stack
RoundOS Data Room's answer:
I'm a startup founder. I've paid for DocSend for years. I think it's not fair in 2026. So I've remade it from scratch, totally free for everyone.
RoundOS Data Room's answer:
Startup founders sharing pitch decks, financial models and diligence documents with investors. Deal teams can also use it for M&A, fund reporting, board materials and other confidential document sharing.
RoundOS Data Room's answer:
Page-level analytics, NDA signing, custom branding and access controls come with the free data room. There is no trial countdown or charge per seat. Documents can be updated without changing the links you've already shared.
RoundOS Data Room's answer:
Send each investor a separate link, see which pages they read, and replace the deck without resending it. For deeper diligence, add financials and legal documents to the same room and control who can see them. The data room stays free as more people join.
