Proof of Usefulness Score
Gaining Momentum

Shelf (YC S22) is a verifiable fintech startup backed by Y Combinator, offering a neobank solution for shared expenses. While the project has legitimate origins and seed-stage funding (~$12M valuation implied), the submission suffers from poor quality, with exaggerated traction claims ('most people have used my product') and confusing metrics. Crucially, external verification reveals the platform is in a pivot or shutdown phase (website forcing withdrawals as of Aug 2024), significantly impacting current utility and traction scores. The score reflects the potential of the YC backing balanced against the current operational uncertainty and low-effort submission.
