Proof of Usefulness Score
Certified Problem Solver

Rarebird Inc. is a legitimate, high-potential biotech coffee startup. The project has verified traction, including a $6.5M Series A raise (approximate), a 2023 SCA 'Best New Product' award, and issued patents for its Paraxanthine (Px) formulation. The technology (Px coffee) is highly innovative and solves a clear problem (caffeine jitters) for a growing market. However, the PoU score is penalized by the submission quality, which contains hyperbolic and factually incorrect claims about audience reach ('everyone', 'most people'), significantly lowering the trust in the applicant's self-reporting despite the strong external evidence.

Description
Introducing our Specialty Coffee Association award-winning Px Coffee. It’s just like your regular coffee, but you’ll feel better during the day and sleep better at night. We asked ourselves, what if coffee could be even better? Instead of caffeine, our coffee contains Px, a caffeine derivative your body naturally makes after you consume caffeine. Just like caffeine, Px wakes you up and reduces fatigue. But unlike caffeine, Px won’t leave you feeling jittery, wired, or over-caffeinated. And if that wasn’t good enough, Px is also cleared from your body faster than caffeine, so you can drink Px coffee later in the day without worrying about it affecting your sleep at night.
