Crowdfunding Without the Trust Problem
Backers don’t send money. They grant claim authority — a delegation that lets the campaign pull from their wallet under specific conditions. The money stays in the backer’s wallet until those conditions are met. The creator proves progress before a single cent moves.
Pitch of the Core Idea
Crowdfunding is broken by a single design flaw: money moves before value is delivered. Kickstarter’s own data shows ~9% of funded projects never deliver. That’s hundreds of millions lost to custodial trust. The global crowdfunding market is $2.14B (2024), growing to $5.53B by 2030 at 17.6% CAGR. Kickstarter alone has facilitated $8B+ in pledges from 250K+ projects.
Pull-based crowdfunding eliminates the trust gap entirely. Backers “pledge” by approving a Tributary delegation. Funds remain in their wallet, earning yield, until the campaign claims them. Failed campaigns create zero friction — delegation expires, money was never touched. No refund process. No disputes. No chargebacks.
Core Mechanics
- Creator launches campaign with funding target, deadline, milestone roadmap
- Backers “pledge” by approving Tributary delegation:
- All-or-nothing mode: Campaign pulls only if total pledged crosses threshold by deadline
- Flexible mode: Campaign pulls at any time, up to each backer’s committed amount
- Milestone mode: Campaign pulls incrementally as milestones verified
- Milestones verified via oracle-confirmed, community vote, or manual backer approval
- Creator submits pull request when milestones hit — Tributary pulls from every backer proportionally
- Failed campaigns: Delegation expires. Money was never touched.
Psychological Hook and Addictiveness
“I committed, but my money is still mine.” Reframes crowdfunding from risky bet into conditional promise. Backers feel generous without feeling exposed. Perceived risk drops to zero — you’re not “giving money,” you’re “authorizing a future pull if they deliver.”
Campaign momentum: Live pledge counter approaching goal creates excitement. Milestone dopamine: Every milestone release is collective celebration — “We did it” energy. Backer dashboard: “You’ve backed 7 projects. 4 delivered, 2 in progress, 1 failed.” Portfolio-style tracking. Social proof cascades: Visible pledges from respected members trigger bandwagon effects.
Brief Market Research
| Metric | Data |
|---|---|
| Crowdfunding Market (2024) | $2.14B |
| Projected (2030) | $5.53B |
| CAGR | 17.6% |
| Kickstarter Total Pledges | $8B+ |
| Kickstarter Funded Projects | 250K+ |
| Non-delivery Rate | ~9% |
Key Competitors:
- Kickstarter: $8B+ pledged, all-or-nothing, custodial, 5% fee + 3-5% processing
- Indiegogo: Flexible funding, broader categories, 5% fee + 3-5% processing
- GoFundMe: Personal/charity focus, 0% platform fee (2.9% + $0.30 processing)
- SeedInvest: Equity crowdfunding, SEC-regulated, for startups
- Republic: Equity crowdfunding, revenue share, SEC-regulated
All require custodial trust or are equity-based. Delegated crowdfunding is trustless by construction.
Business Model
- Platform fee: 3-5% on successful milestone claims (lower than Kickstarter’s 5-8%)
- Backer fee: 1-2% on delegation creation (covers gas + platform cost)
- Creator tools: $10-50/mo for advanced campaign analytics, milestone management
- Featured placement: $100-500 for promoted campaigns
- Success premium: 1-2% bonus fee on campaigns exceeding goal by 50%+

Non-Technological Requirements
- Creator onboarding: Need creators to set up campaigns — two-sided marketplace problem
- Milestone verification: Need reliable verification for non-trivial milestones
- Community building: Need backers to discover and trust campaigns
- Legal compliance: Delegated pledges may be classified differently across jurisdictions
- Fulfillment infrastructure: Need logistics for physical product campaigns
Potential Risks
- Pledge inflation: Backers over-commit across campaigns. If multiple claim simultaneously, wallets could drain. Hard caps essential
- Creator verification: Who verifies milestone is actually met? Oracle manipulation, fake deliverables are hard problems
- Revocation abuse: Backers revoke right before milestone claim, undermining creator trust. Needs lock-up periods
- Cold start problem: Creators won’t use without backers. Backers won’t pledge without credible creators
- Regulatory ambiguity: Is a delegated pledge a “security”? “Pre-sale”? “Donation”? Legal classification varies by jurisdiction
- Gas complexity: Pulling from hundreds of delegated wallets generates significant transaction costs. Batch claiming critical
