AI is changing your portfolio company's economics. Get it built, not advised.

The problem

AI is reshaping your portfolio company's market, whether by threatening its revenue model or by letting competitors cut costs faster. The value-creation plan needs AI results, but the management team is busy running the business and no one inside has built with AI. Every quarter without results shortens the hold period.

02

Who this is for

PE operating partners and portfolio-company CEOs at companies with $10MM+ in revenue that need AI results within the hold period: new revenue, better margins, or both.

03

How I solve it

Each phase de-risks the next: you never pay to scale something that hasn't already earned it.

04

What it's worth

$75MM → $108MM
Exit value · before → after AI, $50MM company

For a $50MM company at a 15% margin, adding 3 points of EBITDA margin with AI is $1.5MM more EBITDA, $15MM in exit value at 10×.

A portfolio company that can show AI already working in its operations also sells at a better multiple. Moving from 10× to 12× adds another $18MM. Together that's 44% more exit value from the same company.

05 — Where AI pays off

The highest-ROI use cases.

These are the use cases that consistently show measurable positive ROI for established companies with $10MM+ in revenue — ranked roughly by how frequently they deliver returns and how quickly they pay back. Your audit maps these against your specific operations.

Based on current data — McKinsey, “The State of AI in 2025” (Nov 2025), mid-market studies, and 2025–2026 ROI reports.
