Bye Blues is a verified French health-tech startup (founded by neuroscientists Daniela Verra & Domitille Boudard, incubated at SEMIA) offering 'Pure Red' light technology to preserve melatonin for parents and babies. While the project has legitimate scientific grounding and has won awards (e.g., Tango & Scan 2022), the submission itself is of very poor quality, containing demonstrable falsehoods ('most people have used my product') and confusing financial data ('marketcap 2500000'). The score reflects a promising early-stage hardware company significantly penalized for unreliable claims and lack of verifiable user traction.
