The Tenant Credit Factor

Traditional consulting typically doesn’t include tenant credit analysis. You’d need to:

  • Order separate credit reports
  • Research each tenant manually
  • No default probability calculation

DDee.ai is the only platform that integrates:

  • Tenant credit scoring
  • Default probability
  • Public + private company analysis
  • All tenants analyzed simultaneously

This capability alone can justify the switch from consulting.

Frequently Asked Questions

Can AI really replace consultants?

For most acquisition DD, yes. AI handles document analysis, financial review, and tenant assessment more quickly and consistently. Human judgment remains valuable for complex negotiations and unique situations.

Is AI accurate enough for institutional deals?

Yes. DDee.ai is used by institutional investors. Citation tracking allows instant verification of any finding—often more reliable than consultant analysis without source links.

What about relationships with consultants?

Relationships have value. Consider using consultants for strategic advice while AI handles routine DD. You’ll engage consultants more productively—on judgment, not data extraction.

How do I justify the switch to stakeholders?

  • Show time savings (weeks → hours)
  • Calculate cost savings per deal
  • Demonstrate coverage (tenant credit, etc.)
  • Pilot on a few deals for comparison
