Frequently Asked Questions
Can DiligenceWorks replace Datasite?
For large multi-party M&A transactions requiring a VDR, no — Datasite's purpose-built data room is the industry standard. For ongoing fund-level deal analysis, pitch deck review, and investment memo generation, DiligenceWorks provides capabilities that Datasite does not offer.
How does DiligenceWorks pricing compare to Datasite?
Different pricing models make direct comparison difficult. Datasite charges per-project or per-page (typically $15K-$50K+ per deal room). DiligenceWorks charges a flat monthly subscription covering unlimited deal analysis across all four modules — making it more economical for teams running multiple concurrent evaluations.
Which is better for data sovereignty?
DiligenceWorks deploys to infrastructure you control — your servers, your jurisdiction. Datasite is a US-headquartered SaaS platform subject to the CLOUD Act. For fund managers in DIFC, Singapore, or the UK with data sovereignty requirements, this is a material difference.
