The project 'Koji' (withkoji.com) was a prominent 'Link in Bio' platform that was acquired by Linktree in December 2023 and subsequently shut down (sunset) on January 31, 2024. The platform no longer exists as an independent, usable service. The submission appears to be low-effort or automated, containing exaggerated claims ('most people have used my product') and inaccurate financial data ($2.5M market cap vs. actual ~$36M raised). Due to the discontinued status of the product and the lack of current utility, the score is minimal, acknowledging only historical technical innovation.
