  • Web

Built with

Next.js 16, TypeScript, Postgres with row-level security, Stripe Connect, OAuth for Instagram, TikTok and YouTube, Playwright

  • A seven-step deal flow — brief, payment, creative, slot, post, report — where both sides sign off each step.
  • Stripe holds the brand's money until the post is live, then pays the creator. Refunds and disputes included.
  • English and French, invoices, spreadsheet reports for brands.
  • Creators connect Instagram, TikTok and YouTube: audience and post stats update daily, every campaign gets click tracking.
