EXECUTIVE SUMMARY

fndr is a decentralized fundraising protocol for tokenized startup equity, built to solve one core problem:
capital sitting idle while innovation waits.

The platform combines:

• ERC-1400 compliant equity tokens

• On-chain yield generation

• Privacy-preserving onboarding via zkPassport

• AI-powered investment and portfolio insights

• Secondary market liquidity for startup shares

Track Alignment:

• DeFi — Yield vaults, secondary markets

• RWA — Tokenized startup equity

• AI — Investment analysis & portfolio intelligence

• ZK — KYC identity proof legit investor and founder

Status:
✅ Core contracts deployed
✅ Secondary market live
✅ AI insights integrated
✅ zkPassport identity verification working

PROBLEM → SOLUTION

Investor Problems

• Raised capital sits idle before deployment

• Paper equity provides no flexibility or efficiency

• Limited access to global, on-chain investors

fndr Solution

• Tokenize startup equity using ERC-1400

• Deploy raised capital into yield-generating ERC-4626 vaults

• Allow tranche-based withdrawals to extend runway

• Enable secondary market trading before exit

• Ensure private, compliant onboarding with zkPassport

• Use AI agents to assist decisions for both sides
