Knock

Marek Klenoti, Lien Chueh, Christian David Bazan, Will G, and Sammy Xf looked at their MacBooks and said "you know what, we should be able to just knock on this thing to control it"—and honestly, they're not wrong. Knock lets you knock on your MacBook lid to trigger actions: wake your Mac, lock it, switch desktop, whatever you want. No more trackpad fumbling, no more keyboard shortcut hunting. Just knock and go.

It's the kind of utility that makes you realize how many pointless motions you make every day. Five taps on the lid to lock your screen, two knocks to wake it up, three to switch apps. That's it. Clean, simple, Mac-native. No bloated settings, no learning curve—just knock.

This is a five-person founding team building a micro-utility for the Mac ecosystem. No funding news, no valuations, no hype. Just a clever little tool that solves a tiny friction point beautifully. If you're a Mac power user who's tired of trackpad acrobatics, this is your new favorite thing.
