Proof of Usefulness Score
Certified Problem Solver

SigmaOS is a legitimate, high-profile productivity browser backed by Y Combinator (S21) and LocalGlobe, with verified funding (~$4M) and significant Product Hunt success (#1 Product of the Month). However, the submission itself is of extremely low quality, featuring exaggerated claims ('most people have used my product'), missing metrics, and lack of detail. While the technology and market fit are strong (innovative workspaces, vertical tabs), the project faces stiff competition (e.g., Arc) and recent community concerns about development velocity. The score reflects the high intrinsic value of the software balanced by the poor quality of the data provided.
