Scoring methodology

Every platform gets a fit score out of 10 from six software criteria. Each criterion has a written formula fed by our facts file, so the same inputs always give the same score.

Last revised Oct 9, 2026

The six criteria

1. Deal workflow coverage26% of the score

Can the software carry a full diligence process on its own, from indexed upload to answered buyer questions?

Formula: Editorial feature rating (60%) plus how many of six deal controls ship natively (Q&A, audit trail, watermarking, redaction, document rights, bulk upload); 1.5 points off without built-in Q&A.
2. Security controls20% of the score

What does the vendor publish about independent audits, and how finely can an admin restrict what guests do with a file?

Formula: 80% of the editorial security rating, plus published attestations: SOC 2 adds 0.9, ISO 27001 adds 1.1, capped at 10.
3. Admin and guest experience18% of the score

How quickly can an admin build the room, and how little does a buyer need to learn before reviewing?

Formula: Editorial ease-of-use rating (75%) and support rating (25%).
4. Pricing transparency14% of the score

Can a buyer see the cost before a sales call and predict the bill if the deal runs long?

Formula: 55% of the editorial value rating plus 1.5, then 3 more for a price published on the vendor site and 0.5 for a free trial, capped at 10.
5. AI and automation13% of the score

Does the software take repetitive work off the admin: sorting, indexing, summarising, routing questions?

Formula: Native AI features (7 points, 2.5 without), plus 1 each for bulk upload, a public API and built-in Q&A workflow.
6. Integrations and IT fit9% of the score

Will the software plug into identity, signing and internal systems without a workaround?

Formula: Base 2, plus single sign-on 2.5, public API 2.5, e-signature 1.5, native mobile app 1.5.

Why a software-first model

Most data room rankings start from the deal. We start from the software: what it does, how secure it is, how much work it takes to run, what it costs and how well it fits into a company’s systems. The deal still shapes the answer, which is why each use-case page re-weights the same criteria for its buyer.

Where the inputs come from

All network facts live in one shared file: entry price and pricing model, free trial, SOC 2 and ISO 27001 status, other listed certifications, deployment, founding year, headquarters, positioning tags and twelve tracked features (Q&A module, audit trail, dynamic watermarking, redaction, e-signature, native mobile app, public API, single sign-on, two-factor login, bulk upload, document rights control and AI features). Editorial ratings for features, security, ease of use, support and value come from our reading of vendor documentation, attestations and published pricing.

How the score is built

  1. Each of the six criteria is calculated from its formula and capped at 10.
  2. Each criterion is multiplied by its weight (shown above), and the results are added.
  3. The total is rounded to one decimal. Ties are broken by the unrounded value, then alphabetically.

A status chip translates the score into plain words: Leader from 8.4, Strong from 7.4, Capable from 6.5 and Specialist below that. Specialist does not mean poor: several specialist tools are excellent at a narrower job, such as deck tracking or client file exchange.

Use-case rankings

The ten use-case pages keep the six criteria but change their weights. A fundraising page, for example, weights admin experience and pricing transparency more heavily, because founders run the room themselves. A small positioning bonus (0.15 per matching tag, at most 0.3) is added when the vendor itself positions the product for that work. Each page prints its weights.

Editorial review. Editors may adjust the final order within a ranking. The value shown reflects that order; every other platform keeps its computed value.

What the score does not include

  • Reviews from other websites. We do not import star ratings or review counts from software marketplaces.
  • Commercial relationships. Affiliate arrangements never change an input or a weight.
  • Hands-on test results. We do not publish measured load times or support response times, because we do not hold test data for every platform.

How often scores change

We re-check the facts file every month and whenever a vendor announces a material change, such as a new certification, a new AI feature or a price change. The re-check date is printed on the ranking pages. When a score moves, the new number appears everywhere at once, because every page reads the same data.
