Competitor Finder API

Hey Product Hunt! 👋 I'm the maker of ChampSignal, a competitor monitoring tool I've been building for the past year. **The backstory:** One of the hardest features to build was auto-discovering competitors when users sign up. I thought it would be simple...just search Google or scrape "alternatives to X" pages. Turns out that gives you garbage. Too much noise. Wrong companies. No way to tell who's a real competitor vs. a random company in the same space. After months of iteration, I finally got it working well. Then I realized: other SaaS builders probably need this too. **So I turned it into an API.** **How it works:** - POST a hostname (like `figma.com`) - GET back ranked competitors with reasons - Each result is classified as direct or indirect - Optional: add $0.10/competitor for enrichment (pricing, employees, market size, etc.) **Pricing:** $0.10 per competitor found. No monthly fees. No minimums. You only pay for results. **Who this is for:** - SaaS platforms that want better onboarding (auto-populate competitor lists) - Market research tools that need competitive intelligence features - Data enrichment services adding competitor data to profiles This is the same engine we use in production for ChampSignal: battle-tested with real paying customers. **🎁 Product Hunt exclusive:** First 100 API requests free for anyone from PH. Just mention you came from here when you reach out. I'd love to hear: 1. What use cases would be most valuable for you? 2. Any features missing that would make this more useful? Happy to answer any questions about how we built it!
