Calculating your Total Addressable Market is hard. Most teams rely on assumptions, reports, or guesses they can’t really trust. Hunter’s TAM Calculator uses real company data to show how many companies match your ideal customer profile and how big your market actually is. It’s free, requires no signup, and helps you go from market sizing to real companies you can act on.
Hey Product Hunt 👋
Jean-Romain from Hunter here.
We built this because market sizing is still way harder than it should be. Most TAMs are based on assumptions, reports, or tools that give you a number you can’t really trust — or act on.
One tool we genuinely liked was Clearbit’s TAM Calculator because it was grounded in real company data. When it was shut down, we felt there was a gap: no simple, free way to calculate a TAM based on actual companies.
So we built one.
Hunter’s TAM Calculator uses real company data to help you size your market, sanity-check your assumptions, and — if you want — turn that into a list you can actually reach out to.
It’s free, no signup required, and we’d really love your feedback.
