From the 2026 Bain & Company hashtag#PE Report: A decade ago, 5% annual EBITDA growth was enough to generate a 2.5x MOIC. Today it's 12%. Multiple expansion is gone. Cheap debt is gone. What's left is operational and commercial performance, and most portcos aren't ready to deliver it from Day 1.

Most commercial due diligence confirms the thesis. It validates what's in the CIM. It asks customers, "Why did you choose Vendor X?" and "How do you like the product?" Supply-side questions that produce surface-level validation, neat answers, and false confidence.
What they don't produce is a growth algorithm.
Demand-side interviews ask different questions: what triggered the change, what nearly stopped you, how did you justify the spend internally. These surface the repeatable buying patterns that actually drove customer decisions. When those patterns repeat across 15-20 recent customers, you have the foundation of a Day 1 GTM playbook. Not a 90-day post-close discovery project. A funded, evidence-based commercial plan that arrives at IC approval.

The EBITDA targets your deal model now requires cannot be achieved through cost reduction alone. Revenue has to do the work.
But most portco commercial teams are running a product-push model, built around features, capabilities and awards. That narrative was designed for a world where buyers came looking. Today, buyers complete 60-70% of their journey before they engage a sales team. By the time your portco shows up, the frame is already set, and your messaging didn't set it.
Demand-side buyer research replaces assumptions with evidence. It builds a commercial motion around the 𝘀𝘁𝗿𝘂𝗴𝗴𝗹𝗶𝗻𝗴 𝗺𝗼𝗺𝗲𝗻𝘁𝘀 that actually move buyers from inertia to action. That's what closes the gap between Year 1 targets and Year 1 results.

LPs now want value creation plans they can describe in one sentence and back with data. "We'll hire a better CMO and fix the messaging" is not a plan.
"We interviewed 8 recent customers during CDD, identified three repeatable buying triggers, and built a Day 1 outbound playbook around the highest-signal segment" is a plan.
