Startup Stories:


The browser that makes YOU fast

✏️ Note from the Founders




If you're anything like us, you work hours a day on the web, buried in a sea of tabs and web apps, constantly losing context and always one click away from being distracted. We believe that a radically different UX can help with this, and that's what we're making.

🌐 SigmaOS is a new type of macOS browser made for work. It's as fast as Safari, and it's built around workspaces and multitasking. Like Slack, in SigmaOS, your browser activity is separated into workspaces - one workspace per project. This product is the overlap of our obsessions:

📑 I (@mahyad) have always been obsessed with organizing because of my ADHD and became a power user of software that could organize and clean up my workflow, like Superhuman and Notion. I was frustrated by how cluttered my desktop was with irrelevant Safari windows and tabs that I didn't need for my work right then.

🧑‍💻 @aliatttar has always been into neo-browsers. Rockmelt (released when he was 11) was the first piece of software he deeply cared about and referred his friends to. Since Rockmelt's shutdown, multiple different neo-browsers came out, but none were as mind-blowing to him. He is also a power user of Photoshop and loves their single-key keyboard shortcuts.

🖥️ @sauravmitra rarely cares about software but is a massive Vim fan. He is obsessed with how fast and powerful Vim makes him at text-editing. Oh and he made a quick product demo sometime recently:

So, if you think Rockmelt crossed with Notion crossed with Vim, that's basically what we're working on! 🔥

That means your data is locked behind biometrics (if available), and malicious cookies can't track your web-activity.

Shortcuts so you can do everything from your keyboard
