Pitch

Close the loop between predicted and realized investment outcomes so the matching system continuously improves ROI accuracy, fairness, and trustworthiness.

TL;DR

  • Track each recommendation from match to long-term outcome.

  • Compare predicted ROI/risk to realized performance.

  • Retrain models with strict governance, versioning, and rollback.

  • Publish model health dashboards for investors and operators.

Problem

Without outcome feedback, matching systems drift and confidence erodes:

  • Predictions can become stale as markets change.

  • Biases persist unnoticed.

  • Users cannot audit whether model recommendations are actually improving returns.

Proposed Solution

Implement an Outcome Intelligence Layer that:

  1. Captures lifecycle events (funded, milestones hit/missed, follow-on rounds, exits, write-downs)

  2. Measures calibration and error by cohort, sector, and stage

  3. Triggers retraining when quality degrades

  4. Enforces governance gates before new model deployment

Implementation

Phase 1: Outcome Telemetry

  • Add immutable event log keyed by recommendation ID.

  • Define canonical outcome windows (3/6/12/24/36 months).

  • Attach confidence bands at recommendation time for later calibration checks.

Phase 2: Evaluation Framework

  • Track metrics by cohort:

  • calibration error, rank correlation with realized returns, false-positive funding recommendations.

  • Detect drift in market regime and feature distributions.

  • Run shadow-mode candidate models continuously.

Phase 3: Governance + Transparency

  • Require deployment gates:

  • minimum calibration improvement, no fairness regression, reproducible training artifact.

  • Publish model cards and changelogs.

  • Support one-click rollback to previous stable model.

Success Metrics

  • Calibration Error: -25% within 2 quarters.

  • Ranking Quality: Higher Spearman correlation between predicted and realized ROI.

  • Fairness Stability: No significant degradation across geography/sector/founder-background slices.

  • Trust Metric: Increased investor acceptance of top recommendations.

Risks

  • Long feedback cycles in venture outcomes → Use intermediate leading indicators and survival analysis.

  • Attribution ambiguity → Separate model recommendation quality from post-investment support effects.

  • Privacy and compliance → Differential access control and auditable data lineage.

  • Operational overhead → Automate evaluation and gating workflows.

Why This Matters

A matching engine is only valuable if it stays correct over time. Governance plus feedback transforms it from a static ranking tool into a reliable capital allocation system that compounds ROI advantage.

Detailed Implementation Plan

Phase A — Outcome Telemetry Contract

  1. Define standardized outcome schema (win/loss, cost variance, schedule variance, quality outcome).
  2. Build ingestion endpoints and integrity checks.
  3. Add outcome confidence and source provenance fields.

Phase B — Governance Evaluation Loop

  1. Compare model predictions vs realized outcomes.
  2. Flag drift and underperforming model components.
  3. Trigger review workflows for retraining or policy changes.

Phase C — Governance Board Outputs

  1. Generate periodic model health reports.
  2. Maintain change logs for model updates and rationale.
  3. Require signoff on high-impact model policy changes.

Validation Checklist

  • Outcome ingestion completeness
  • Drift detection sensitivity/specificity
  • Governance decision turnaround SLAs
