Datasite

High-volume M&A data room platform running 55,000+ deals a year

Overview

Datasite provides data rooms and deal software for mergers and acquisitions. It says it runs more than 55,000 M&A deals a year, has served more than 2 million users and more than US$10 trillion of transaction value since 2020, and was used on four of the five largest M&A deals of 2025[1]. It is owned by funds managed by the private-equity firm CapVest[5].

The company has broadened from the data room into a deal lifecycle suite. Its product list includes Prepare for deal staging, Diligence as a sell-side data room, Acquire as a buy-side data room, Archive for closed deals, pipeline management, Grata for private-market intelligence covering more than 20 million companies, Blueflame for agentic AI and Sherpany for board management, plus a bring-your-own-AI connector and MCP partnerships[1]. In February 2024 Datasite agreed a proposed takeover of the Australian data room provider Ansarada at A$2.50 a share, valuing it at about A$236 million, conditional on Ansarada’s non-deal products being carved out to its co-founder[5].

Datasite reports ISO/IEC 27001, 27017, 27018 and 27701 certification, SOC 2 Type II attestation, and says it was the first data room certified to ISO/IEC 42001 for AI governance[1]. Support runs 24/7 in more than 20 languages[1]. Pricing is not published and the product is priced for advisers and corporates running sizeable transactions; smaller sellers may find it more than they need.
