Score detail

Why Ellty is first

Ellty combines the investor control set (Q&A, viewer watermarks, view and download rights, 2-step login and an activity log) with AI help, a published price of $149 a month and a 14-day free trial. It has the highest speed-to-launch and cost-clarity scores in the list, so a founder or a deal team can open a working room the same day.

iDeals and Datasite follow, both with ISO 27001, single sign-on and redaction, priced by quote.

Questions about the ranking

How are these data rooms ranked?

Each room gets five scores out of 10: investor access control (26%), diligence workflow (22%), security and compliance (18%), speed to launch (18%) and cost clarity (16%). The weighted total is the score shown. Details on how we score.

Which data room is best for a startup raise?

See our startup fundraising ranking, which gives more weight to speed to launch and price. Ellty leads that list.

Are cheaper data rooms less secure?

Not necessarily. Price follows the sales model more than security. Compare the certifications and the six investor controls listed in each review before you decide.

Can a vendor pay to rank higher?

No, partners cannot buy a position. We may earn a commission from some links, as explained in our affiliate notice.

Why is DocSend near the bottom?

DocSend is built for sharing a pitch deck with page-level tracking. It does not list Q&A, folder permissions or redaction, which a full diligence process needs, so it scores low on our diligence workflow and access criteria.
