Proof of Usefulness Score
Industry Mainstay

Scarf (scarf.sh) is a verified, VC-backed company (Series Seed/A, ~$7.3M raised) providing significant utility in the open-source software supply chain. While the submission itself was of extremely poor quality (containing hyperbolic claims like 'most people have used my product' and empty data fields), external evaluation confirms substantial real-world traction, including tracking over 2 billion downloads annually and a team size consistent with the 26-31 employee range. The project scores highly on utility and market timing, but the final score is dampened by the low quality of the provided evidence.

Description
Scarf builds maintainer-friendly tools for open-source software distribution and analytics. Scarf's mission is to help open-source creators run data-driven projects and be more successful.\n\nWe're a small team of friendly people who love open-source, obsess about package management, and are building the next generation of tools for effective, observable, and equitable software distribution. Scarf began in Oakland, California, but our growing team is currently spread out across the Americas and Europe.\n\nWe believe that building systems that empower open-source developers will result in better quality software for everyone. We believe that the open-source community as a whole should not only be sharing source code, but also data about that source code and how it is used. These principles will help us build for a future of equity and broader-scale collaboration in open-source.
