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.

Private offline notepad

Gravity is a private, ultra-fast notes app with one stream and a simple rule: bump what matters. Forget folders and tags, just open and type. Instant capture with shortcuts keeps your flow, while older notes naturally drift down. If something is still relevant, hit bump to bring it back to the top. It syncs via iCloud with no accounts, tracking, or subscriptions. Inspired by the Karpathy method, Gravity isn't a complex second brain. It's just your thoughts. Stop organizing and start thinking.
