Overview
XVenture is a full-stack web application that replaces the traditional venture capital gatekeeping model with a transparent, milestone-driven funding marketplace purpose-built for AI startups. Founders list projects with structured milestones and target raises; investors browse, filter, compare, and fund them directly — with capital released automatically when milestones are verified on-chain.
The platform handles the full lifecycle from project discovery to revenue distribution, targeting the gap between early-stage AI founders who can't access traditional VC and investors who want direct, auditable exposure to AI innovation.
Product Features
For Investors
- Discover & filter projects by category (NLP, Computer Vision, Robotics, ML), risk level, funding stage, and timeline
- Algorithmic risk scoring across funding velocity, timeline, founder KYC status, and deal terms
- Side-by-side project comparison (up to 3 projects simultaneously)
- Portfolio dashboard with real-time milestone tracking, ROI calculations, and revenue distributions
- Saved searches and personalized AI-driven recommendations based on browsing history
- Wallet connection via Web3Modal for on-chain investment execution
For Founders
- Project creation wizard with milestone definition, tranche amounts, and funding target configuration
- KYC verification flow for investor trust and platform credibility
- Analytics dashboard tracking funding progress, investor count, and revenue metrics
- Draft auto-save across wizard steps
Platform-Wide
- Three-tier role system — founder, investor, admin — with protected routes and separate interfaces
- Admin moderation dashboard for project approval and user management
- Demo mode with time-boxed sessions (2hr expiry) and mock data injection, sandboxed from real transactions
- Replit Auth / OpenID Connect for authentication; session storage in PostgreSQL
Architecture Highlights
Monorepo with a shared schema layer. A single shared/schema.ts file is consumed by both the React frontend and the Express backend. Drizzle ORM schemas auto-generate Zod validators, ensuring form validation and API enforcement stay in lockstep — no hand-maintained dual schemas.
Client-side filtering with server-side state. Projects are fetched via TanStack Query and all filtering (category, risk score, sort order) runs client-side. This keeps the API simple and the UX snappy, with the tradeoff that filter logic and risk scoring live in custom hooks rather than SQL.
Demo architecture without a separate app. Rather than spinning up a separate demo environment, demo users are authenticated with an isDemo flag on the session object. A middleware layer intercepts investment, KYC, and revenue claim endpoints and short-circuits them. Mock projects are injected at the component level in the Discover page so demo users see a fully-populated experience.
Web3 integration as a progressive layer. Wagmi and Viem handle wallet connection and Ethereum interactions, but the platform degrades gracefully for users without a wallet. Blockchain transaction hashes are stored in the database for audit trail, with the core UX not dependent on on-chain confirmation in the current build.
Normalized relational schema with financial precision. The PostgreSQL schema uses decimal types for all monetary amounts and defines explicit status enums for projects (draft → pending → active → completed) and milestones (pending → claimed → verified → released). Foreign key constraints enforce referential integrity across users, projects, milestones, investments, and revenue distributions.
