What SigmaOS does

SigmaOS is a new type of browser designed for founders, researchers, and content creators to make you better and faster at working on the web. You work 7+ hours a day on the web. Buried in a sea of 100+ tabs and 10+ web-apps 🤯, you constantly lose context for why you did what you did, and are always one click away from being distracted. We took apart the browser for you, and rebuilt a new experience from the ground-up, for the FASTEST and most PRODUCTIVE work. ⚡

We're building SigmaOS, a browser redesigned specifically for founders, researchers, and content creators who spend long hours online. It helps users manage dozens of tabs and multiple web apps by keeping context clear and reducing distractions to boost productivity and speed.

Where do you live now, and where would the company be based after YC?

We live in San Francisco and London. The company is based in both San Francisco, CA, USA, and London, England, United Kingdom.

Explain your decision regarding location.

Our team is split between SF and London, reflecting where founders and key team members live. We want to stay close to our users in these innovation hubs and draw from talent in both locations.

Frequently Asked Questions

Is this the real SigmaOS YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from SigmaOS's public data (launch notes, founder backgrounds, product description). It shows how a company like SigmaOS would present itself to YC, not the text they submitted.
