UACC + PSC vs
Traditional Blended Finance
Traditional blended finance revolutionised development capital by de-risking deals for private investors. UACC + PSC completes the picture—the framework plus the instrument that makes catalytic capital perpetual.
What Traditional Blended Finance Solved
Development finance institutions (DFIs) and foundations faced a scale problem: public and philanthropic capital alone couldn't fund the $4.2 trillion annual SDG gap. Blended finance solved this by using concessional capital—grants, guarantees, first-loss tranches—to de-risk deals enough for commercial investors to participate.
This was a genuine breakthrough. But it optimises for one question: "How do we mobilise more private capital?" UACC asks a different question: "How do we make catalytic capital perpetual?"
The UACC 5-Layer Framework
Traditional blended finance operates primarily in Layers 1-3. UACC adds Layers 4-5—the missing pieces that enable perpetual catalytic capital.
Risk Absorption
First-loss tranches, guarantees, concessional debt
Temporal Smoothing
Matching capital cadence to mission cycles
Crowd-In
Mobilizing follow-on commercial capital
System Value Formation
Compounding social returns across cycles
Perpetual Cycles
Self-sustaining regeneration via beneficiary participation
The Unlock
Traditional blended finance stops at crowd-in—mobilising private capital for a deal. UACC continues to system value formation and perpetual cycles—where beneficiaries become contributors and capital regenerates indefinitely. This is where Perpetual Social Capital™ (PSC) operates as the enabling instrument.

Feature Comparison
| Feature | Traditional BF | UACC + PSC |
|---|---|---|
| Primary Question | How do we mobilize more private capital? | How do we make catalytic capital perpetual? |
| Layers Addressed | L1-L3 (Risk, partial Temporal, Crowd-In) | L1-L5 (Full stack including System Value & Perpetuation) |
| Key Metric | Leverage ratio (1:4 typical) | System Value Multiplier (10-30×) |
| Where Returns Go | Back to commercial investors | Forward to next beneficiaries (L4-L5) |
| Time Horizon | Deal lifecycle (5-10 years) | Perpetual (multi-generational) |
| Beneficiary Role | Recipients of investment outcomes | Active participants who pay forward |
| Scale Determinant | Commercial viability of assets | Beneficiary capacity to participate |
| Proven Track Record | $200B+ mobilized annually | Emerging (case studies at scale exist) |
Which Layers Do You Need?
The right approach depends on context. Sometimes L1-L3 is sufficient. Often, adding L4-L5 transforms outcomes.
Large Infrastructure
L1-L3Traditional blended finance excels here. Add L4-L5 for community benefit covenants.
Dutch water boards: L1-L3 for infrastructure + L4-L5 levy recycling (17M protected)
Climate Mitigation
L1-L3 + optional L4-L5Blended for renewables with commercial returns. UACC full stack for adaptation funds.
Solar: L1-L3 | Community resilience funds: full L1-L5
Education & Workforce
L1-L5 (full stack)Students gain capacity → can pay forward. Full UACC stack maximizes system value.
Income-share agreements with pay-forward covenants
Healthcare Access
L1-L5 (full stack)Patients recover → can contribute. Aboriginal health cooperatives serve millions.
ACCHO model: community-controlled, self-sustaining
Social Housing
L1-L5 (full stack)Vienna model: blended builds assets (L1-L3), perpetual covenants maintain affordability (L4-L5).
60% of Vienna housed through this hybrid approach
Worker Ownership
L4-L5 primaryCapital stays in system, workers become owners. Mondragon: 80,000+ workers.
No extraction needed—pure L4-L5 mechanics
Scale is not the constraint. Dutch water boards (17M people), Vienna housing (60% of city), and Mondragon (80,000+ workers) all operate at massive scale using L4-L5 mechanics.
PSC: The Instrument for L4-L5
Perpetual Social Capital™ is the instrument that enables Layers 4 and 5. It's not a replacement for blended finance—it's the completion.

The recycling mechanism for L4-L5
How It Works
- •Capital deployed as gifts to beneficiaries
- •Beneficiaries pay forward when they succeed
- •Recycled capital serves the next cohort
- •System value compounds over cycles
Key Metrics
Integration point: Use traditional blended finance (L1-L3) to build infrastructure and mobilise capital. Add PSC (L4-L5) to ensure benefits perpetuate and compound. The Vienna housing model does exactly this.
The Theoretical Foundation
The Unified Architecture for Catalytic Capital™ paper formalises the 5-layer framework, including the mathematical conditions for each layer and the interactions between them. The Perpetual Social Capital™ paper details the L4-L5 mechanics.
