Category Standard

Penny Black (now Stord Unbox) is a verified, high-utility B2B SaaS platform for personalized ecommerce packaging, acquired by the unicorn logistics company Stord in 2024. Despite the submission containing low-quality, inaccurate claims (e.g., 'most people have used my product', 'marketcap: null'), external verification confirms significant traction, including £2.8M+ in pre-acquisition funding and integration into a global logistics network. The score reflects the project's proven real-world success and exit, heavily discounted in the Response Quality and Quality Factor metrics due to the poor submission data.
