Martijn Smit - Lostdomain

👋 Hey, I'm Martijn. I build software that helps people work smarter, track their productivity, and improve their digital experience. I'm a technical founder, developer, and marketer with 25+ years in IT, and a track record of building and growing products.

I love solving complex problems, making data useful, and helping technical products connect with the right audience. Whether it's building software, improving developer experience, or refining technical messaging, I focus on creating things that work—efficiently and effectively.

My Products

I'm currently working on a few products that help people work smarter and improve their digital experience. Here are a few of my latest projects:

WhatPulse

WhatPulse is a productivity application that tracks time spent in apps, and the effort you put into your keyboard and mouse. It's a great tool to track your productivity and see where you spend your time.

WhatPulse Professional

WhatPulse Professional is the enterprise version of WhatPulse, with additional features and private dashboards. Map which apps your team uses, track productivity, and improve your team's efficiency.

MuteDeck

MuteDeck is a desktop app to manage meetings (i.e., mute/unmute, control your video, and more), works with Zoom, Teams, and others. It integrates with Stream Deck, Loupedeck, and others to let you control your meetings with a single button.
