Business Idea League — Product Hunt meets fantasy football meets a public startup studio

Build an open-source "Business Idea League" for a podcast or creator audience. The app should turn business ideas into a public game where listeners can submit, scout, rank, and back ideas before any product is built. Core concept: A creator posts business ideas. The audience acts like a fantasy sports league for startups: they draft ideas, allocate credits, vote on which ones are most promising, and track which ideas actually become products, revenue, or public builds. Build a working demo with: 1. Idea submission page — Users can submit a short business idea, target customer, pricing guess, and why now. 2. AI-generated idea card — For each idea, generate a structured business card with: one-line description, target customer, pain point, simple monetization model, distribution strategy, 7-day validation plan, estimated build difficulty, estimated build cost, biggest risk, and "why this could be big". 3. Public draft board — A ranked list of ideas with votes, comments, estimated build cost, validation status, and whether the idea is open, funded, building, launched, or dead. 4. Backing mechanism — Users can allocate demo credits to ideas they believe in. The highest-backed ideas rise up the leaderboard. 5. Scout leaderboard — Track users who spot good ideas early. If an idea later gets funded, built, or marked successful, early backers and scouts gain reputation. 6. Build pipeline page — For funded ideas, show a public build page with milestones, spend, artifacts, files, and status updates. 7. Validation tracker — Before building, each idea can run lightweight validation: landing page clicks, waitlist signups, survey responses, manual notes, and founder comments. 8. Creator/admin dashboard — Approve ideas, edit AI summaries, mark validation progress, start a build, or kill an idea with a public reason. 9. Demo content — Seed with fictional business ideas inspired by common podcast themes: boring businesses, AI tools, newsletters, marketplaces, local services, data products, niche communities. 10. Export — Export all public idea data as JSON/CSV. The product should feel like "Product Hunt meets fantasy football meets a public startup studio." Important constraints: Do not scrape podcast transcripts in v1. Do not depend on any specific podcast brand. Make it white-label so any creator/community can use it. Use mock payments and demo credits for now. Make the first version simple, fast, and inspectable. Ship with: working web app, demo data, admin interface, README, setup instructions, database schema, API routes, tests where practical, MIT license.

Produce a complete implementation blueprint for the open-source Business Idea League: product requirements, user roles, core game loops, status lifecycle, reputation rules, admin workflows, white-label constraints, accessibility goals, data model draft, API route map, page inventory, wireframe-level layouts, and recommended stack for a simple inspectable v1 web app.

Create the initial repository structure for a working web app using a practical open-source stack. Deliver the application shell, routing, layout, styling system, white-label configuration, environment handling, local development setup, database connection, basic CI/test scaffolding, and placeholder pages for all major product areas.

Implement the database schema and domain layer for ideas, users, demo credits, votes, comments, backing allocations, statuses, validation events, build milestones, artifacts, admin actions, and reputation events. Add migrations, typed data access utilities, seed scripts, and fictional demo data covering boring businesses, AI tools, newsletters, marketplaces, local services, data products, and niche communities.

Build the public idea submission page with fields for business idea, target customer, pricing guess, and why now. Implement AI-generated structured idea cards with a provider abstraction, deterministic local fallback, editable generated fields, validation, loading/error states, persistence, and tests. The card should include one-line description, customer, pain point, monetization, distribution, 7-day validation plan, build difficulty, cost estimate, biggest risk, and why it could be big.

Implement the public draft board with ranked ideas, statuses, vote counts, comment counts, estimated build cost, validation state, and sorting/filtering by status/category/rank. Add idea detail pages with the full AI card, discussion area, validation summary, backing summary, status history, and shareable public URLs. Include responsive UI polish and route-level tests.

Implement the fantasy-league-style participation mechanics: demo credit balances, credit allocation to ideas, vote/unvote behavior, comments, backing history, leaderboard-impacting events, duplicate/abuse guardrails suitable for a demo app, and clear UI showing how backed ideas rise on the board. Include API routes, server-side validation, optimistic UI where practical, and tests for credit accounting edge cases.

Build the scout leaderboard and reputation engine. Track early supporters, scouts, voters, and backers; award reputation when an idea becomes funded, building, launched, successful, or otherwise validated; support transparent scoring explanations; and render public user/scout profiles with their backed ideas and reputation history. Include deterministic tests for scoring rules and status transitions.

Implement validation tracking for each idea before build starts: landing page click counts, waitlist signups, survey response counts, manual notes, founder/admin comments, timestamps, validation status, lightweight charts or summaries, and public validation history. Include admin-editable validation entries, public read-only views, API routes, and tests for validation state changes.

Build the creator/admin dashboard for approving submitted ideas, editing AI summaries, changing idea status, marking validation progress, starting a build, killing an idea with a public reason, managing seeded/demo users, and reviewing recent activity. Use simple v1 admin authentication suitable for local/demo deployment, add audit records for important actions, and include admin workflow tests.

Implement the public build pipeline for funded ideas: build overview pages, milestone lists, spend tracking, artifacts/files links, status updates, build notes, public progress indicators, and status transitions from funded to building to launched or dead. Include admin controls to add/edit milestones, spend entries, artifacts, and updates, with public pages that make each build inspectable.

Add export functionality for all public idea data as JSON and CSV, including ideas, rankings, backing totals, validation summaries, build pipeline data, and reputation summaries. Document public API routes, add admin export controls, include schema/version metadata, and provide inspectability pages or utilities so creators can understand and reuse their community data.

Complete the release-quality open-source demo: polish the Product Hunt meets fantasy football meets public startup studio feel, improve responsive and accessible UI states, add practical unit/integration tests, prepare README and setup instructions, document database schema and API routes, include deployment notes, add MIT license, verify seed/demo flows end-to-end, and produce a final QA checklist with known limitations and next-step roadmap.
