Proof of Usefulness Score
Category Standard

Rakuten Viki is a well-established, high-utility streaming platform with global reach and verified significant traction (acquired for $200M). However, the submission quality is exceptionally poor, containing vague claims ('most people have used my product'), inaccurate data entry (market cap listed as monthly revenue), and missing fields. The high score reflects the verifiable reality of the business entity (unicorn status, 50M+ users) despite the low-quality application.
