Dillien is a virtual data room platform built for teams running M&A, real estate, and fundraising transactions. It combines secure document management with built-in due diligence tools — including request tracking, access control, Q&A, and a findings dashboard — giving both sides of a deal a single organised workspace from start to close. Organised DD request list with resolution tracking. Maps each outstanding item to the uploaded file that answers it, keeping both buy-side and sell-side teams aligned throughout the review process. Structured Q&A tool for managing due diligence questions within the VDR. Threads are linked to relevant data room items and tracked by status, priority, and number of replies.

What would work better for LinkedIn specifically? A few directions I can take them: Option A — Story-led Opens with a real scenario or pain point a practitioner would recognise, then connects it naturally to the feature shown. Option B — Insight-led Leads with a sharp observation about how deals or fundraising actually work, uses the screenshot as the proof point. Option C — Short & punchy 3-4 lines max. No hashtag overload. Sounds like a founder or practitioner posting, not a marketing team. Option D — Educational Explains what the feature does and why it matters in plain language — good for audiences who may not know VDRs well. Which direction feels right, and is there a tone you prefer — founder voice, broker voice, or platform/product voice?You said: mix of A and Dmix of A and D16:25Claude responded: Got it.Got it. Here are the reworked captions — story-led opening, educational payoff, one per image per industry. Industry 1 — Commercial Real Estate Image 1 — Files & Requests We've all been on a deal where nobody could agree on what had been shared and what hadn't. A broker uploads the lease summary to an email thread. A buyer asks for the title deed. Someone cc's the wrong person. Three weeks in, the seller is still waiting for an indicative offer because two documents are sitting in someone's downloads folder. Dillien fixes this by giving every party — sell-side and buy-side — a single structured workspace. Documents live in organised folders. Every request is tracked against the file that resolves it. Progress is visible in real time. Nobody has to ask "was that uploaded?" because the answer is always right there. Fewer chasers. Faster offers. Cleaner process. Image 2 — DD Report A buyer's adviser reviews the lease summary and flags two issues — the DataPilot break option and the Cabinet Moreau expiry. They write it up in a Word doc, email it to their IC, and two weeks later nobody can remember which version of the memo is current. Dillien's buy-side dashboard changes how findings are captured. As reviewers go through documents, they log findings directly in the platform — categorised as critical, negative, neutral, or positive, attributed to the reviewer, and linked to the exact file that triggered them. By the time the IC meeting happens, the DD work isn't scattered across inboxes. It's structured, searchable, and ready to export as a report. Image 3 — Granular Access In a competitive sale process, not every bidder should see the same information at the same time. Early-stage bidders get the marketing documents. Shortlisted parties get the financials. Only the preferred buyer sees the sensitive legal agreements. And your lawyer gets view access but not download rights. Dillien lets you manage all of this at the document level, per user, without any technical setup. You toggle access on or off — for one person, one folder, or one specific file — and the change takes effect immediately. It's the kind of control that used to require a call to your IT team. Image 4 — Q&A The moment a buyer asks a question about a lease break option and the answer arrives three days later in a reply-all email chain with twelve people copied, the deal slows down. Dillien's Q&A module keeps every question and every answer inside the data room, threaded against the document it relates to. Questions are tagged by priority. Replies are timestamped. Both sides can see what's open, what's been answered, and what's still pending — without digging through inboxes. It also creates something most deals lack entirely: a complete, auditable record of everything that was said during the process. Image 5 — Request List Due diligence checklists are sent at the start of every deal. And then they get lost. The buyer's lawyer emails a list of 40 items. The broker uploads some of them. The seller asks which ones are still missing. Someone builds a tracker in Excel. The Excel gets out of date. Three weeks later, the same items are being requested again. Dillien's request list replaces that cycle. Every DD item lives in the platform, mapped to the file that resolves it. When a document is uploaded, the request it answers is marked as resolved — automatically. Both sides see the same list, in the same state, in real time. Industry 2 — Private Equity / M&A Image 1 — Files & Requests The average M&A process involves dozens of document requests, multiple advisers on each side, and a timeline that compresses faster than anyone expects. Most of the friction doesn't come from the deal itself — it comes from the process around it. Who uploaded what. Which version is current. Which requests are still open. Whether the buyer's lawyer has actually seen the shareholders agreement yet. Dillien is built to eliminate that friction. The sell-side team uploads documents into a structured folder system. Every request is tracked from open to resolved. Progress is visible to everyone with access — so advisers spend less time managing the process and more time moving it forward. Image 2 — DD Report In PE due diligence, the gap between "we reviewed the documents" and "we have a clear view of the risks" is usually filled by a lot of unstructured notes, emails, and late-night memos. Dillien's buy-side dashboard gives deal teams a structured way to capture findings as they review. Each finding is categorised — critical, negative, neutral, positive — attributed to the reviewer, and pinned to the source document. When it's time to write the IC paper, the work is already done. It doesn't replace judgement. It just means the judgement your team exercises is captured somewhere useful. Image 3 — Granular Access A management buyout involves the management team, the PE house, their lawyers, their lenders, their financial advisers, and sometimes a second bidder in a parallel process. Every one of them has a different information need and a different level of trust. Dillien handles this with document-level access controls that you manage yourself, without any technical overhead. View rights and download rights are set independently. You can open up or restrict access to a single folder, a single file, or a single user — instantly, from the same screen you use to run the rest of the deal. Image 4 — Q&A In every deal we've seen, the Q&A is where momentum either builds or dies. A buyer asks a pointed question. If the answer comes back quickly, clearly, and with a document attached, confidence grows. If it disappears into an email thread and comes back three days later with a vague response, doubt sets in. Dillien's Q&A module keeps every exchange inside the data room — threaded, prioritised, linked to the relevant document, and visible to the right people on both sides. Fast answers are easier to give when the question is sitting right next to the document it's about. Image 5 — Request List Every sell-side adviser has had the same experience: a buyer's DD checklist arrives, the team scrambles to pull the documents together, and three weeks later somebody asks for something that was uploaded on day one. Dillien's request list is designed to end that loop. Each item on the DD checklist is mapped directly to the file that answers it. When a document is uploaded and linked to a request, that request is resolved. Both sides see the same status. Nothing falls through the gaps and nothing gets re-requested unnecessarily. Industry 3 — Venture Capital / Startup Fundraising Image 1 — Files & Requests Most founders build their first data room by creating a Google Drive folder and hoping for the best. Then an investor asks for something specific, the founder can't find it, and three emails later the deal has lost its momentum. Dillien gives founders a proper data room from day one — with a structured folder system, document upload tracking, and a real-time view of which investor requests have been answered and which haven't. It looks professional because it is professional. And in a fundraise, how you run the process sends a signal about how you run the company. Image 2 — DD Report VC analysts review a lot of data rooms. The ones that stand out aren't necessarily the ones with the best numbers — they're the ones where the reviewers can get in, find what they need, and form a clear view quickly. Dillien's buy-side dashboard helps analysts do exactly that. As they work through documents, they log findings in real time — categorised by risk level, linked to the source file, attributed to the reviewer. By the time they're presenting to the partnership, their DD is already structured and shareable. No last-minute memo scramble. Image 3 — Granular Access A founder raising a Series A might have 15 investors in their data room at different stages of the process. Early conversations don't need access to the cap table or the shareholder agreement. A term sheet holder does. Dillien lets founders manage this precisely. Access is controlled at the document level, per user, and can be updated instantly as a conversation progresses. You decide what each investor sees and when they see it — without creating separate data rooms or manually emailing documents to different people. Image 4 — Q&A An investor asks a sharp question about your churn assumptions. You answer it well — with context, with data, with a reference to the model you uploaded last week. That exchange, if it happens in an email, lives in one person's inbox and disappears from the record. Dillien's Q&A module keeps that conversation inside the data room, threaded against the document it relates to, visible to everyone on the deal. Investors see a founder who responds clearly and quickly. Founders have a complete record of every question asked and every answer given — which matters more than most people realise when the lawyers arrive. Image 5 — Request List Investor DD requests follow a pattern. Cap table, financial model, founder agreements, product roadmap, customer references. You'll answer versions of the same list in every round you raise. Dillien's request list lets you build that structure once and reuse it. Each item is mapped to the document that answers it. When investors check the list, they can see exactly what's been provided and what's pending — without a follow-up email. And when the next round comes around, the framework is already there. You said: shorter with no detail about the document visibleshorter with no detail about the document visible16:27Claude responded: Got it.Got it. Here are the reworked captions — clean, short, no references to specific content in the screenshots. Industry 1 — Commercial Real Estate Image 1 — Files & Requests Every CRE deal has a moment where someone asks "was that document uploaded?" and nobody has a clean answer. Dillien replaces that uncertainty with a structured workspace where every document and every request has a clear status — visible to everyone in the process, in real time. Image 2 — DD Report Buyers form views on an asset while they're reviewing it, not after. Dillien gives buy-side teams a way to capture those views — categorised by risk level, linked to the source document — so nothing gets lost between the data room and the investment committee. Image 3 — Granular Access A competitive sale process means different parties need different information at different times. Dillien lets you control exactly who sees what — down to a single document, a single user — without any technical overhead. Image 4 — Q&A Deal questions that live in email threads slow everything down. Dillien keeps every exchange between buyer and seller inside the data room — threaded, prioritised, and tied to the document it's about. The full conversation is always in one place. Image 5 — Request List The DD checklist gets sent. Documents get uploaded. And then somehow things still go missing. Dillien maps every request to the file that resolves it so both sides always know exactly where things stand. Industry 2 — Private Equity / M&A Image 1 — Files & Requests The friction in most M&A processes isn't the deal — it's the document management around it. Dillien gives every party a single structured workspace where uploads, requests, and progress are tracked automatically. Image 2 — DD Report Good due diligence produces clear views on risk. Dillien makes sure those views are captured in a structured, shareable format as reviewers work through the data room — not assembled from notes and emails after the fact. Image 3 — Granular Access Every party in a deal has a different information need and a different level of trust. Dillien gives administrators precise control over access — per user, per document — so the right information reaches the right people at the right time. Image 4 — Q&A The pace of a deal is often set by how fast questions get answered. Dillien keeps every question, every response, and every follow-up inside the data room — structured, searchable, and on the record. Image 5 — Request List Sell-side teams spend too much time re-sending documents that were already uploaded. Dillien's request list makes the status of every DD item visible to both sides — so nothing gets requested twice and nothing falls through the gaps. Industry 3 — Venture Capital / Startup Fundraising Image 1 — Files & Requests How a founder runs their data room tells an investor something about how they run their company. Dillien gives founding teams a structured, professional process — with every document request tracked from open to resolved. Image 2 — DD Report VC analysts move fast. Dillien lets them capture findings in real time as they review — categorised, attributed, and ready to present — so the work done in the data room doesn't have to be rebuilt into a memo afterwards. Image 3 — Granular Access Not every investor in your process is at the same stage. Dillien lets founders control access at the document level so early conversations stay high-level and serious conversations go deeper — without creating separate data rooms for each party. Image 4 — Q&A An investor's questions — and your answers — are part of the diligence record. Dillien keeps that conversation structured and inside the data room, so nothing important ends up buried in an email thread from three weeks ago. Image 5 — Request List Investor DD requests follow the same pattern every round. Dillien lets you build the structure once, map documents to requests as they're uploaded, and give investors a live view of what's been provided — no follow-up emails needed. You said: more in this style :more in this style : Files, folder and request view Dillien provides an organized overview of the data room, showcasing key document categories, and seller activity, facilitating efficient management and collaboration during the M&A transaction process.16:29Claude responded: Got it.Got it.
