Sponsor Marketplace

Pharmaceutical companies, CROs, biotech firms, AI companies, universities, and NGOs can create data programs, fund patient compensation, and access aggregate compliance data — all without ever seeing individual patient records.

Sponsor Types

Type	Typical Use Case	Data Interest
Pharma	Drug development, post-market surveillance	Medication response, adverse events, biomarkers
CRO	Clinical trial feasibility, site selection	Patient demographics, condition prevalence
Biotech	Target validation, companion diagnostics	Genomic data, molecular biomarkers
AI Company	Training diagnostic/predictive models	Medical imaging, clinical text, wearable signals
University	Epidemiological research, population health	Longitudinal health records, survey data
NGO	Global health initiatives, rare disease registries	Under-served population data, treatment access

Program Creation Flow

Sponsor → Create Program → Define Requirements → System Generates Commitments → Program Goes Live

  1. POST /api/SponsorPrograms
     ├── title, description, category
     ├── promisedAnnualUsd (per patient)
     ├── budgetCommitted (total)
     ├── termMonths
     └── requirements[] (with hidden thresholds)
  
  2. For each requirement:
     ├── requirementKey: "weekly_glucose"
     ├── dataCategory: "vitals" (patient sees this)
     ├── patientInstruction: "Submit your glucose readings" (patient sees this)
     ├── dataType: "glucose_mg_dl" (oracle-only)
     ├── threshold: 180 (oracle-only, HIDDEN)
     ├── comparator: 1 (LTE = must be ≤ 180)
     └── frequency: "weekly"
  
  3. System generates:
     ├── Poseidon(salt, dataType, threshold, comparator) → commitment
     ├── Stores commitment publicly (patients can verify it exists)
     └── Stores threshold encrypted (oracle decrypts at evaluation time)

What Patients See vs. What's Hidden

Visible to Patient	Hidden from Patient
"Submit your activity data"	Threshold: ≥ 5,000 steps
"Submit your vitals weekly"	Threshold: systolic ≤ 140
"Submit glucose readings"	Threshold: fasting 70–130 range
Commitment hash (0x1a2b...)	Salt, threshold, comparator
Data category	Data type (internal key)
Frequency	Exact evaluation logic

Funding & Escrow

Sponsors fund programs through Stripe Connect escrow:

Budget States:
  committed → deposited → spent
  $50,000     $25,000     $8,340

Program Funding Status:
  seeking_sponsor → partially_funded → fully_funded
  (0% deposited)    (1-99%)            (100% of projected need)

Funding Formula

Total Needed = promisedAnnualUsd × maxParticipants × (termMonths / 12)

Example:
  $120/yr × 500 patients × 2 years = $120,000 total needed
  Deposit $30,000 → partially_funded (25%)
  Deposit $90,000 more → fully_funded (100%)

Early Bird Economics

Programs in seeking_sponsor status still accept patient enrollments. These early enrollees earn a 1.5x multiplier because they took the risk of contributing before funding was guaranteed. When funding arrives, their promised credits convert to real payouts first.

Sponsor Dashboard

Sponsors access an aggregate-only dashboard. Individual patient data is never exposed.

Available Metrics

Metric	Description	Privacy Level
Active participants	Count of enrolled patients	Aggregate
Average compliance	Mean compliance score across all enrollees	Aggregate
Fulfillment rate	% of submissions that pass oracle verification	Aggregate
Total submissions	Count of all blind submissions received	Aggregate
Geographic breakdown	Country-level counts (opt-in)	Country-level
Budget committed/deposited/spent/remaining	Financial tracking	Sponsor-only
Total credits earned/paid/pending	Credit conversion tracking	Aggregate

What Sponsors Cannot See

• Individual patient identities
• Raw health data values
• Individual compliance scores
• Specific requirement thresholds that were missed
• Patient location beyond country level
• Data commitment contents (Poseidon hashes only)

Future: Sponsor Marketplace Discovery

Planned features for a public sponsor marketplace:

• Program templates: Pre-built requirement sets for common conditions
• Competitive bidding: Multiple sponsors bid on the same dataset
• Data licensing: Perpetual royalty model (patients earn when model generates revenue)
• Cross-program analytics: Aggregate insights across multiple programs
• Regulatory compliance packages: HIPAA/GDPR-ready program templates
• Diversity goals: Auto-adjust pricing to fill geographic representation gaps
