Find the brands that should already be sponsoring you.

SponsorFlow helps small podcasts, newsletters, and student publications find sponsors. You tell it about your audience, and it researches brands that are a real fit, finds the right contact, and drafts the pitch for you.
I built it after doing this by hand for The Experience Exchange, the outdoor magazine I run at Washington and Lee. Our first issue brought in $5,000 in ad revenue, and I wanted to turn that process into a tool other small creators could use.
What it does
- AI sponsor research: uses the Claude API to find brands that match a creator's niche and audience, with a reason for each match
- Customer portal: every order gets a private link where the customer sees their sponsor list and tracks outreach
- Payments: Stripe checkout with a webhook that creates the order automatically
- Automated outreach: scheduled email campaigns with follow-ups and daily send limits, sent from the product's own domain
- Admin dashboard: one place to manage orders, campaigns, and replies
Built with
Next.js 16, React 19, TypeScript, Tailwind CSS 4, Neon Postgres, Claude API (Anthropic), Stripe, Resend, Vercel (hosting and cron jobs)
