Proof of Usefulness Score
Category Standard

CastLabs is a verified, established (founded 2007) provider of critical digital video infrastructure, specializing in DRM, player SDKs, and watermarking. As a certified Google Widevine Third Party Labs (3PL) partner, the company holds a significant and technically demanding position in the global OTT market. While the submission itself was low-effort (claiming audience reach is 'everyone' and providing vague traction metrics), external verification confirms strong B2B utility, a roster of major clients (e.g., Plex, OSN, Formuler), and a team size likely between 50-100+ (verifying the 'established' nature, though 350 may include contractors). The project scores highly on utility and innovation, penalized only by the poor quality of the submission text.
