Datasite review for startups.

The platform many investment banks run sell-side processes on: AI tools, a phone app, SSO and redaction, bought through a quote.

Facts checked Sep 30, 2026. Editorial score, no paid placement.

Overview.

Datasite dates from 1999 and is American. When a banker runs the sale of a company, there is a good chance the buyers will read in Datasite.

It brings AI sorting, a dedicated app for buyers on the move and enterprise sign-on, backed by ISO 27001 and SOC 2. There is no trial; access starts with a demo and a proposal.

Why a founder would pick it

You meet it when an adviser runs your exit. It is rarely the economical choice for a round you run yourself.
