Why Dillien?

Due diligence in M&A and other transactions is characterized by manual, repetitive tasks, fragmented information flow, and limited oversight. Traditional virtual data rooms have largely served as static storage spaces, offering little support for the process.

With domain expertise and first-hand transaction experience, we know there is much to gain by optimizing how due diligence is carried out. We believe it should run more efficiently, and that the data room — where documents stay and collaboration takes place — must be the starting point.

That’s why we’ve built a platform that cuts the noise out of due diligence: A smarter data room with process-optimizing features that enable all stakeholders to work more efficiently. Dillien accelerates every step, from request lists embedded directly in the data room and tied to file structures, to enhanced Q&A, faster reviews, seamless collaboration, integrated project management, and auto-generated reports.

All-in-one

Switching between tools to manage requests, review documents, track findings, and coordinate tasks slows the process down. Dillien brings everything together in one platform, optimized for the way due diligence should run.

Review documents, flag issues, note concerns, ask questions, and manage requests — all directly in the data room. Assign responsibilities, set deadlines, and track progress with automatic reminders, while a real-time dashboard keeps teams and clients aligned.

Export structured packages or generate a ready-to-use due diligence report with the built-in report generator. By uniting review, collaboration, and project management, Dillien streamlines the workflow, reduces manual effort, and drives faster, smoother execution.

Resolve requests

Managing request lists separately means endless updates, re-uploads, and constant context switching between sheets and systems. In Dillien, the request list is fully integrated into the platform and directly tied to the file structure, so everything can be managed in one place. Resolve requests by adding text answers and files or marking applicability directly in the platform — eliminating confusion, streamlining collaboration, and saving time.

Q&A

Enhanced Q&A, where questions, answers, and supporting files appear both in request-specific threads and on the Queries page, giving you full visibility. Everything happens directly in the data room, in the right context — ensuring clear communication and a more efficient process for all stakeholders.

Project management

Due diligence involves many stakeholders, parallel workstreams, and tight deadlines. Dillien helps everyone stay aligned and communicate — both internally and across the table — with built-in tools for project management and collaboration. Assign responsibilities and tasks, set deadlines, track progress, and trigger automatic reminders for outstanding tasks — ensuring clear oversight, less manual coordination, and a faster path to closing.

Report generator

Skip the system toggling and copy-paste marathons. With in-app review and note-taking, Dillien keeps everything tied to the right context. The built-in report generator then compiles findings and recommendations into a clean, structured due diligence report — ready in seconds. Export as-is, or adapt it for internal use and client delivery. Faster, more consistent reporting with less manual work.
