I built an API that finds competitors for any company in seconds (for SaaS onboarding flows)

Hey IH!

I've been working on ChampSignal, a competitor monitoring tool, for a while now. One feature our users kept asking for: "Can you find my competitors for me?"

So I built an algorithm to do that. After months of tweaking, it got good enough that other founders started asking if they could use it in their own products.

That's when I realized: this should be an API.

The problem I kept seeing

When you're building a SaaS, you often want to know who your user's competitors are. Maybe you're:

  • Building onboarding that pre-fills competitor lists
  • Running a market intelligence tool
  • Enriching company data

But building a competitor finder yourself is a pain. You need data sources, filtering logic, ranking algorithms. We spent months getting ours right.

How the API works

One call. Pass a hostname (like "figma.com"). Get back a ranked list of competitors with:

  • Name and hostname
  • Whether they're a direct or indirect competitor
  • A short reason why they compete

That's it.

If you want more, add enrichment for $0.10/competitor: pricing info, target market, employee count, founded year, and ownership status.

Pricing

Pay-as-you-go. $0.10 per competitor found. No monthly fee. No minimums.

For most companies, we return 5-15 competitors, so a lookup costs roughly $0.50 to $1.50.

Who's this for?

Mostly other devs building products where competitor data would help. A few use cases I've seen:

  • Onboarding flows that suggest competitors
  • CRM enrichment
  • Competitive analysis features

    Quick example of what the response looks like:

    POST /api/competitors
    { "hostname": "figma.com" }
    

    Returns:

    • sketch.com (DIRECT) - "Mac-focused vector UI design platform..."
    • penpot.app (DIRECT) - "Open-source browser-based design tool..."
    • framer.com (DIRECT) - "Visual web-design and prototyping platform..."
    • miro.com (INDIRECT) - "Visual collaboration workspace..."

    Each competitor comes with a reason so you can show your users why they should care about that competitor.
