Security questionnaires and DDQs

# Which DDQ software handles investor due diligence questionnaires?

Short answer

4 tools document investor or asset-manager DDQ workflows: Inventive AI, Tribble, Thalamus AI and RequestFX. Fund teams should test with an ILPA-style or allocator DDQ they actually received, since generic vendor-risk DDQ support does not carry over automatically.

## Why this question matters

Investor DDQs ask fund managers about strategy, operations, compliance and performance. They share the questionnaire format with vendor-risk DDQs but draw on different documents and different reviewers.

## Which one fits your situation

- If you also answer customer security reviews, start with [Inventive AI](/inventive-ai).

## What to test in a trial

1. Use last year’s completed investor DDQ and this year’s blank version.
2. Check that compliance review routing covers performance and regulatory statements.

## Caveats

- Very few tools in this directory document investor DDQs specifically.

## How we decided who qualifies

Only RFP, DDQ and questionnaire response tools with a published profile are checked. A tool is named here only when its record shows the rule above, either in a sourced research fact or in the reviewed profile, and we publish an answer only when at least three tools qualify. A tool missing from the table may still do this; it has not been documented in a way we could source. Read the [research methodology](/methodology) for how facts are dated and corrected.

## More questions on this topic

Is an investor DDQ the same as a vendor DDQ?

No. An investor DDQ assesses a fund manager for allocators. A vendor DDQ assesses a supplier for a customer.
