You publish a four-domain measurement framework most impact investors don't even attempt. The portcos operationalize it. The critical inflection point you've already named is what makes the framework survive replay across 25 portcos — or break under follow-on diligence.
$12M · 25 portcos · 4 domains · one substrate
The framework you publish is the discipline your portcos sell to schools and clinicians. The inflection point you named is what makes the recursion hold — or break.
- Resource Flows · co-investor follow-on into youth mental health
- Relationships · across companies · funders · field partners
- Power Dynamics · shift toward lived-experience leadership + youth voice
- Mental Models · narrative · stigma · measurement reframing
- → Portfolio Impact Composite — "rare in early-stage impact investing"
60% suicide-risk reduction · 66% eating-disorder symptom reduction · gains in youth mood, stress, confidence.
4.3M YOUNG PEOPLE · 3.8M BIPOC · 3.3M LOW-INCOME
25 portcos across mental health (Equip · Mightier), schools (Hazel), AI-mediated touch (Koko · ReflexAI), and lived-experience-led design (Caraway · TRACE · Lex).
Each portco runs a different evidence regime — clinical assessment · gameplay biometric · school telemetry · AI output · text · identity-tagged data. Lived-experience signal threads through all four domains, qualitative, easily lost in transitions. The framework stays clean. The per-portco cadence drifts unmeasured.
Three pressures converging through 2026.
- Equip Series C · "impact beyond outputs?" → answer must live beyond the IC memo.
- Resource Flows · "how much follow-on?" → audit chain.
- Power Dynamics · "did we shift power?" → methodology overlay.
The framework is the public layer. The portco evidence regimes are the recursive layer. The substrate is the same primitive at both levels.
You publish a measurement standard most impact investors don't even attempt. Equip ships symptom reductions, Hazel ships school-care, Mightier ships emotional regulation, Koko ships AI-mediated reach, ReflexAI ships counselor-training rigor. The discipline they ship to clinicians and schools is the discipline your portfolio reporting needs for co-investors and philanthropic peers. One framework. Two layers.
- AUDIT CHAIN
- every domain reading per portco hash-chained, append-only, never-deletable, evidence mode tagged at emission [verified] [model-derived] [partner-supplied] [self-reported] [stale]. Lived-experience signal — qualitative, easily lost in transition — captured as first-class.
- METHODOLOGY OVERLAY · L2 YAML
- each portco's four-domain reading encoded as inspectable YAML. The framework you publish becomes the same artifact the fund operates on internally — versioned, portable, replay-tested across cohort vintages.

built for four-domain replay · before the inflection window closes
Pick one portco. We rebuild its four-domain chain in synthetic. You see whether it survives replay or doesn't.
Phase 0 is not a pilot. Two-week structural diagnostic against one portco of your choice — synthetic data only, no production access. The question it answers is narrow and load-bearing: under follow-on diligence and the inflection you've named, does this portco's four-domain reading hold across two methodology versions — and does the portfolio-level framework defense hold beneath it? Three artifacts come out the other side. You keep all three whether you continue or not.
ONE PORTCO · TWO METHODOLOGY VERSIONS · SYNTHETIC EVIDENCE · FOUR-DOMAIN REPLAY MADE VISIBLE
THE DIAGNOSTIC · WHAT TWO WEEKS PRODUCES
- 01Methodology overlay v0.1
The portco's four-domain mapping encoded as L2 YAML — evidence regime made inspectable. Lived-experience signal captured as first-class. Versioned. Portable. Runs in your environment without us.
- 02Audit chain replay
The chain populated against synthetic readings across two methodology versions — domain drift simulated before a co-investor diligence cycle starts citing it. Drift visible or not.
- 03Cost model
Framed against follow-on capital deployment, co-investor diligence cadence, philanthropic peer review, and the strategic planning window. Risks named. What Phase 1 costs. Where this approach breaks.
Pressure-test the substrate. Ask where it breaks.
The substrate answers in its own voice — the same primitive we'd install on one of your portcos. Not a demo. The actual reasoning surface.
STREAMING · κ ≥ 0.85 · ANONYMITY HOLDS · CITATIONS BY DEFAULT
If the pattern reads true, the next step is to test whether one portco is the right Phase 0 target.
If relevant, I can send a short async questionnaire — no call needed — and build a no-charge synthetic-data Phase 0 PoC "Hopelab AI OS". Within two weeks, replay one AI-native portco's evidence chain against Article 6(1) before the notified bodies start citing it.
