Total addressable Market calculator

Launched this week
Calculate your TAM from 100M+ real companies
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. 👉 How do you currently calculate your TAM? 👉 What’s the hardest part for you today? I’ll be around all day to answer questions and learn from your feedback ❤️

what a useful tool i like it, did you try to evaluate your own TAM with it?

While TAM doesn't roll off the tongue, it is the first step of understanding how many businesses you could see as a buyer. I've been asking for something like this for a while.

It's a crucial part of building a market strategy, and for the longest time, you'd have to go through some long-winded, expensive steps to gather the data:

- Access Gartner, Forrester, IDC, etc. reports to help you understand the size of the market (typically behind a paywall)
- Buy a licence to SalesNavigator or 3rd party lists
- Dump all of this into a spreadsheet...

...and even then, I've spoken to 100s of founders and product owners who aren't confident in the numbers they're using in investment pitches or when deciding which markets to take their solution to next.

Thanks for sharing this! 🙏

@jamesmilsom90 amazing

Adam Lababidi

Will it support TAM calculation for to C busniesses in the future?

Jeanro Krupa

@wei_yan4 we are 100% focus on BtoB

Mike Wycislik

Hi Team, congrats on your launch. 👌 What is your database for TAM calculation? How do you ensure that your calculations are real?

Jeanro Krupa

@mike_wycislik that's the key. We use the same b2b database for the TAM than for our discover feature more info here https://hunter.io/b2b-database

Love the focus on actionability versus theoretical TAMs.

Curious how you think about overcounting when firmographic filters look right on paper but buying intent or budget reality lags behind the dataset.

Jeanro Krupa

@justin_press the cool thing it's not theory as you said actionable. So I would say cold emailing a sample of the TAM reveals the buying intent, does that make any sense ?
