Datasite review

Where Datasite fits

Datasite has been in the market since 1999 and is a regular choice for investment banks and mid-to-large corporate finance boutiques. Its design centres on the sell-side adviser: who is reading what, which bidders are serious, and how to keep thousands of documents in order across a long process. It scores 9.0 overall in our table, with top marks for security and deal tools and a lower score for ease of use.

Buyer analytics and AI on a sell-side mandate

The feature that wins Datasite most UK mandates is engagement reporting. On a private equity exit with ten or more bidders in round one, an adviser wants to know which teams opened the financial model, who downloaded the property schedule and which group went quiet. Combined with a structured Q&A and dynamic watermarks, that gives the adviser material for deciding who goes through to round two.

AI tools and built-in redaction help on volume. A carve-out from a UK group often involves stripping personal data and unrelated business information from shared contracts, and doing it inside the room avoids a second copy floating around in another system.

There is also a timing point. Large UK sell-side processes often run a phased disclosure: an information memorandum and limited data in round one, then the full room for two or three shortlisted bidders, and finally confirmatory diligence for the preferred party. Datasite’s permission model handles that staging well, and the engagement data from round one gives the adviser evidence when explaining to the client why certain bidders were not taken forward.

Access, devices and identity

SSO matters to large UK corporates, and the mobile app is a convenience for principals. Under UK GDPR the security of personal data on phones is still your responsibility as controller, so agree whether mobile access is allowed for bidder teams.

Costs and the quote process

Datasite does not publish prices and has no free trial. Pricing is typically agreed per project, and large rooms can cost substantially more than subscription-priced alternatives. Ask for a quote in pounds, ask how overruns are charged, and check whether VAT is included. Our costs guide explains the common models.

Without a free trial, the best substitute is a scripted demo. Send Datasite a short brief beforehand (number of bidders, rough document count, the phases you plan) and ask them to show the permission changes between rounds and the reports you would send to the client. That tells you more than a general tour, and it gives you something concrete to compare against other quotes.

Datasite or Intralinks

Both are heavyweight, quote-only rooms with deep security credentials. Datasite’s AI features, mobile app and analytics give it an edge on adviser-led sales. Intralinks is often preferred where a bank already has a firm-wide relationship.

Simpler alternatives

If your deal is a single-buyer sale, a seed round or a property transaction with a few dozen documents, Datasite is more machine than you need. Ellty covers the same core diligence tools (permissions, Q&A, watermarking, audit trail) with published pricing and a 14-day free trial, which makes it easier to budget for a smaller mandate.
