The category endgame is capital allocation.
Pension allocators, sovereign wealth funds, and insurance asset managers control trillions in long-duration capital seeking inflation-linked yields, ESG-aligned exposure, and rating-agency-grade structure. They do not write tickets to single operators. They allocate to GP funds and rated paper. Both require something the asset-heavy economy has never had: 36+ months of standardized, attested, statistically-meaningful cohort data.
Twelve named allocators. Trillions of long-duration capital.
The world's largest pension, sovereign, and insurance asset managers have mandate-driven appetite for the kind of long-duration, inflation-linked, ESG-aligned, infrastructure-linked credit the physical economy produces — if it arrives in the right vehicle, with the right rating, against the right evidence. The vehicle is a GP fund or a rated paper structure. The rating requires 36+ months of standardized cohort data. The evidence is what the vault produces.
NRSRO methodology — active 2024–2025.
Rated paper is gated by the methodology each rating agency applies. KBRA dominates esoteric and emerging asset classes (solar ABS, project finance, distributed energy receivables). Moody's, S&P, and Fitch lead in mature asset classes. DBRS Morningstar covers commercial PACE and other niche structures. Every methodology has the same skeleton: historical static-pool loss curves, granular-pool default/severity distributions, structural credit enhancement (overcollateralization, reserves, waterfall), true-sale and non-consolidation legal opinions, servicer infrastructure with SSAE-18 attestation, and continuous monitoring.

Solar ABS proved the template. Each clean vintage tightens the spread.
Residential solar lease ABS — issued by Sunrun (SUNRN), GoodLeap (TIP), and others — is the closest precedent for what asset-heavy operator paper will look like. KBRA rates the senior tranches single-A. The pricing data tells the story: each additional vintage of clean static-pool data + each independent attestation cycle tightens senior spreads roughly 10–25 bps. Sunrun's SUNRN July 2025 priced at +240 bps over benchmark; SUNRN April 2026 — same issuer, twelve months later — priced at +220 bps. A twenty-basis-point improvement from one additional year of attested track record.
+240 → +220 bps in twelve months.
Same issuer, same asset class, same rating, same structure. The only thing that changed was a full year of additional clean static-pool data and continued servicer performance. This is the math underneath the 36-month vintage threshold. Each year of data tightens the spread, builds rating-agency conviction in the distribution, and enables granular-pool methodology rather than concentrated-pool fallback. The IG unlock vs unrated alt-credit is typically a 300–500 bps spread differential.
The full picture — simultaneously.
Rated paper unlocks last because each element is necessary, none alone is sufficient. The 36-month threshold is not arbitrary — it's the rating-agency floor for fitting a granular-pool default/loss distribution that survives the data-insufficiency haircut. Below it, agencies use concentrated-pool methodology (each obligor individually rated), which kills the math for sub-IG operators.
Rating-agency level
- 3+ years historical static-pool loss curves · by vintage
- Default frequency + recovery / severity · by obligor stratification
- Standardized, field-consistent obligor data · same fields, same definitions, same time series
- Monthly servicer reports + annual auditor attestation (SSAE-18 / SOC-1 Type II is the floor)
- Structural protections · OC, reserve account, excess spread, sequential/pro-rata waterfall, triggers
- True-sale + non-consolidation legal opinions
- Backup-servicer agreement + servicer financial review
- Statistical mass · 75–100+ comparable obligors for granular-pool
Allocator level
- GP track record · 3+ funds preferred · first-time funds get smaller checks
- IRR / DPI by vintage · loss / recovery history
- ESG / climate metrics · aligned with TCFD / CSSB / ISSB
- GP commitment · 1–5% skin-in-game in fund

- Audited financial statements · fund + obligor
- Liquidity / lock-up profile · vehicle structure
"Trust the servicer" becomes "verify the proof."
The structural risk premium that rating agencies build into ratings for esoteric / emerging asset classes is partly a "model risk" surcharge — typically worth 25–75 bps of senior spread. This surcharge exists because agencies cannot independently verify the servicer's data; they sample, audit, and price the residual uncertainty. Cryptographically attested servicer reports collapse the trust gap. ZKP attestation lets the agency cryptographically verify rather than rely on auditor sampling, and continuous monitoring replaces the quarterly servicer-certificate cadence. Both shifts move the structural risk premium toward zero.

|---|---|
| Standardized, hash-chained operator data identical fields, definitions, time series across 100+ obligorsGranular-pool methodology unlocked | Above the 75–100 obligor floor, agencies can fit binomial/beta default distributions. Below it, concentrated-pool methodology punishes sub-IG operators. Crossing the threshold is the IG unlock. |
| Realized loss + recovery data over 36+ months · severity by default cause0% recovery assumption removed | Without realized recovery data, agencies assume 0% recovery — devastating for asset-heavy operators where collateral recovery is the whole thesis. With data: severity priced from actuals. |
| ZKP-attested servicer reports cryptographic verification vs auditor sampling25–75 bps "model risk" surcharge eliminated | Substitutes for or augments SSAE-18 SOC-1 attestation. Agencies can verify the proof rather than trust the sample. The structural risk premium tightens. |
| Continuous monitoring real-time covenant attestation vs quarterly certificatesTighter trigger structures · lower OC | Replaces the quarterly servicer-certificate cadence. Supports tighter trigger structures (lower overcollateralization, tighter reserves), which reduces the cost of structural enhancement. |

Climate-aligned rated paper is the fastest-growing pool of capital.
Pension allocators face mandate-driven appetite for climate-aligned, ESG-reportable, infrastructure-linked credit. The numbers are concrete: CalPERS' Climate Action Plan targets $100B in climate-solution investments. CalSTRS' SISS explicitly hunts for opportunistic climate infrastructure that doesn't fit standard asset-allocation buckets. APG is doubling global infrastructure over five years. NBIM's mandate now permits unlisted renewable infrastructure. The capital exists. The constraint is the substrate that produces audit-grade carbon-impact-per-address and deployment-outcome attribution at rating-agency quality.
KBRA's ESG Global Rating Methodology is live.
Already applied to consumer-loan ABS (e.g., Foundation Finance Trust 2025-1). The framework for ESG-overlay on operator-cash-flow ABS exists today — the constraint is producing data of rating-agency quality. Solar + battery + EV charging + grid-services operators fit the mandate. Allometry's vault produces exactly the data the ESG-overlay methodology requires — natively, hash-chained, attested at write, with per-address granularity.
The 36-month threshold is where the curve stabilizes.
Three years of attested ledger is the seasoning window where cumulative loss curves stabilize. Subprime auto, credit cards, and solar ABS all stabilize around 24–36 months. The 36-month threshold is not arbitrary — it is the rating-agency floor for fitting a granular-pool default/loss distribution that survives the "data-insufficiency" haircut. Combined with 100+ comparable operators in the cohort (the statistical-mass floor), the combination unlocks granular-pool methodology, which is what enables investment-grade ratings on operator-cash-flow paper.
This is the category endgame. Once Allometry is the substrate underneath rated paper backed by operator cash flows, every layer of the capital stack — banks, infrastructure funds, insurers, pensions, sovereigns — plugs in through the same vault. Capital allocation, at address granularity. The pre-seed buys the first design partners. The Series A turns the graph into orchestration. The Series B turns orchestration into capital. The Series C is when rated paper goes to market.
