01 / The diligence framework

The Institutional
Diligence Blind Spot

Most commercial due diligence (CDD) reports are 100-page academic exercises that examine TAM and macro market trends, but fail to answer the most critical question:

Does the operation actually
work post-close?

Financial audits tell you what happened historically. We tell your Investment Committee what breaks tomorrow.

01
Owner-Dependency

What client relationships walk out the door when the founder leaves?

02
EBITDA Durability

Which pro-forma add-backs are recurring operational overhead in disguise?

03
Operational Drag

Where are the productivity ceilings and unpriced capex liabilities?

02 / Advisory engagement models

From first screen.
To the first 100 days.

Three focused engagements. Clear decisions before commitment. Practical execution after close.
