Best virtual data rooms in Singapore

How to read this ranking

The overall score is a weighted average, so a room can rank in the middle and still be the right answer for your deal. A file sharing tool with a low score may be all a seed-stage founder needs; an enterprise room with heavy procurement may suit a bank-led auction better than its overall position suggests. Use the overall list to build a shortlist, then check the use case pages, which re-weight the same measures for 74 Singapore deal types.

Rating bands help with a quick read: Outstanding is 8.6 and above, Strong 7.8 to 8.5, Solid 7.0 to 7.7, and Niche below 7.0. Niche does not mean poor; it usually means a product built for a narrower job, such as tracking who opened a pitch deck.

What separates the top of the list

Almost every product records an audit trail and stamps watermarks. The differences that move rooms up the list are a proper buyer Q&A workflow (13 of 18 list one), control over whether each file can be downloaded (15 of 18), a second login factor for every user (14 of 18), AI help for sorting and searching large rooms (5 of 18) and a price you can see before talking to sales (8 of 18). Rooms that combine all of these score well on deal tools, permissions and cost at the same time.

The top five in brief

1. Ellty 9.2/10 · about S$191 a month

Q&A, watermarks, view control and bidder analytics cover a full sell-side process, and the published price makes the room cost predictable. Investors see a tidy room, founders see who opened the deck and the cap table, and the trial lets the round start before a contract.

2. iDeals 8.6/10 · Quoted per project

Certifications, SSO and redaction suit bank-run auctions with many bidders. Security documentation and SSO help it through a MAS-style vendor review.

3. Datasite 8.5/10 · Quoted per project

Global banks running regional auctions often standardise on it. Analytics and Q&A suit large auctions with many bidders.

4. Ansarada 8.5/10 · Quoted per project

AI insight and Q&A suit competitive sale processes. Used on infrastructure and energy deals across the region.

5. Firmex 8.3/10 · Quoted per project

Simple administration suits firms running many small matters. Redaction and Q&A cover a mid-market sale.

Quote-based or published price?

10 of the 18 rooms only quote. Their prices depend on users, data volume and how long the deal runs, and a mid-market Singapore sale typically lands in the low thousands of dollars a month. Published-price rooms let you budget on day one and usually let you start on a free trial. Neither model is better in itself; what matters is the total over the realistic life of your deal, including extension fees if signing slips by a quarter. The pricing guide compares both in SGD.

Singapore checks before you sign

• PDPA terms. Make sure the vendor will support the use, return and destruction terms you put in the NDA under the business asset transaction exception. See the PDPA and your data room.
• Hosting. Only one room in our data lists a Singapore region. If your buyer, lender or regulator wants data kept in Singapore, ask every vendor before shortlisting.
• Vendor reviews. Banks, insurers and fund managers review suppliers under MAS technology risk expectations. Have certification reports ready; see MAS technology risk rules.
• GST. Overseas vendors charge 9% GST to companies that are not GST-registered. Registered companies quote their GST number; partly exempt businesses use reverse charge.
• Support hours. The last week before signing is when you need help fastest. Confirm who answers during Singapore office hours.

Shortlist in three steps

1. Pick the use case closest to your deal and note its top five.
2. Remove rooms that miss a must-have tool, such as Q&A for an auction or masking for HR-heavy files.
3. Price the remaining rooms in the calculator for your expected months and users, then trial the ones that allow it.
