Covering all your needs

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.

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.

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.

Export

Export what you need — from single files to the complete data room — with just a few clicks. The export function generates a structured package of selected content — whether files, requests, Q&A, noted concerns, or activity logs — which you can store in your own archive and keep available for the future.

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.
