Three tiers of diligence

Real diligence on an alts commitment lives in three layers — operator, deal, synthesis. The mistake most LPs make is collapsing them into one.

Three tiers, in order: operator, deal, synthesis.

Tier 1 is operator diligence — who you're hiring for the next three to ten years. Tier 2 is deal diligence — what's being offered, how it's structured, how it survives the stress tests that matter (refi cliff, exit cap compression, NOI vs. wage growth). Tier 3 is synthesis — how this commitment relates to the rest of your portfolio and your prior commitments to this sponsor.

The order matters. If the operator fails the first cut, you don't do the deal work. If the deal fails the stress test, you don't do the synthesis. Each tier is a filter on the next, not a parallel checklist, and that's what separates a framework from a list. The early filters do the heavy lifting, so the work that survives is the work that matters.

Most LPs collapse the three. They read a PPM front to back, look at the sponsor section as one of many sections, and never separate "is this a fund I'd commit to" from "is this a fund I'd commit to from this sponsor" from "does this commitment make sense alongside what I already hold." Three different questions. They deserve three different answers.

Tier 1 is the work you can't redo later. The others compound on top of it.

Operator diligence is the work that takes the longest the first time and the shortest every subsequent time, because sponsor knowledge is evergreen. Prior-fund actual-vs-projected by vintage, fee structure, team turnover, communication cadence during the windows when communication was actually hard — that file, once built, is still good when the same sponsor's sixth deal lands.

Tier 2 — deal diligence — depreciates the moment you commit. The stress test, the capital stack analysis, the rate-sensitivity table all get filed away. This is where AI is the highest leverage: extract structured data from the PPM, run rules against it, produce a stress surface in seconds instead of hours. It's also where the deterministic-framework piece matters — the same questions get asked of every deal, by design, not by mood.

Tier 3 — synthesis — is the work that ties the deal to the rest of your life. How does this commitment change your alt concentration? How does it interact with your existing exposure to this sponsor? How does it sit alongside the other deals you're actively diligencing? This is the part most LPs do last, in their head, in the car on the way home from the sponsor meeting. It belongs in the file.

The framework is worth more than any single brief.

Briefs are outputs. Frameworks are processes. You buy a brief by paying for the work; you build a framework by doing it the same way every time. The brief on any given deal is useful for a quarter. The framework is useful for every deal you'll ever review.

Which is why the same questions get asked of every deal, even the ones you're sure you'll commit to. The deal that "feels fine" is the one that needs the framework most, because vibes are where bad commitments hide. The vibes-passing deal that fails three years in is the deal that didn't get the rigor it should have, and the framework is what keeps that from happening.

Each tier is independently useful, but the real value compounds when they're done together. The sponsor work earns yield on every future deal from that operator. The deal work gets faster once the framework is built. Synthesis is what turns a pile of commitments into a portfolio.
