How to choose a due diligence platform for private markets.
What are the best due diligence platforms for private markets?
The best due diligence platforms for private markets keep diligence current after the first review, test claims against outside evidence, link findings across company, deal, vehicle, fund, manager and portfolio, and carry them into the committee record. Reuben AI is decision infrastructure built on this model, offered to investment teams and embedded by platforms for their clients.
The problem today
- Diligence is done once, then goes stale as the market moves.
- Findings sit in documents that the committee cannot trace back to evidence.
- Company, fund and manager reviews are run in separate tools and never connect.
How Reuben AI helps
Living diligence. Findings are re-checked as new information appears, not frozen at the first review.
Six linked levels. Company, deal, vehicle, fund, manager and portfolio sit in one linked record.
Evidence behind every finding. Each conclusion shows the material it came from.
Built to be embedded. Platforms can offer the same diligence to their own investor clients.
Criteria to compare diligence platforms
- Does diligence stay current after the first review?
- Can every finding be traced to its evidence?
- Are company, fund and manager findings linked, or separate?
- Does the work flow into the investment committee record?
- Where is data held, and can residency be chosen?
- Can a platform embed or distribute it to its own clients?
