IdeaHub — Exclusive Idea Pitching Platform

What

• Invite-only social platform where members pitch startup ideas and get honest feedback from a curated community
• Each pitch supports a title, description, optional video or deck embed, and tags — plus upvotes, comments, and huddle rooms
• Semantic deduplication layer that flags similar existing pitches before you submit, preventing the feed from filling with near-duplicates
• Fund modal lets members signal financial interest in a concept; huddle rooms let matched collaborators spin up focused async threads
• Role-based system: member, moderator, and admin — plus a playground mode for testing the full moderation flow

Why

• The best early-stage ideas die from lack of the right audience at the right moment, not lack of effort or intelligence
• Twitter and LinkedIn reward polished announcements, not raw half-baked concepts that genuinely need critique
• Most feedback platforms (Product Hunt, Reddit) are public and loud — they incentivise marketing over honest early-stage feedback
• Invite-only format creates a trusted environment where people share genuinely unfinished ideas without fear of being copied or dismissed
• The semantic similarity layer solves a real problem: duplicate ideas fragment feedback instead of consolidating it around the strongest version

How

• Supabase handles auth, Postgres data storage, Row-Level Security policies, and Edge Functions for background embedding generation
• pgvector stores embeddings for each pitch; a 72% cosine similarity threshold triggers duplicate detection on every new submission
• Hybrid search combines full-text search (FTS) for keyword queries with semantic vector search for conceptual matches
• Next.js 16 App Router with React 19, Tailwind CSS v4, shadcn/ui components, and Framer Motion for feed animations
• Huddle requests are lightweight — any member can request a focused thread on a pitch; creator accepts and the room opens
• Moderation is role-scoped: moderators can hide pitches; admins can remove content and manage member access
