Stratosyst is a legitimate Czech aerospace startup developing High Altitude Pseudo-Satellites (HAPS) and a verified winner of the 2018 Galileo Masters award. However, the submission quality is critically poor, containing demonstrably false claims (e.g., stating "most people have used my product" for a pre-commercial deep-tech aerospace platform). While the technology shows high utility and innovation potential within the defense and telecom sectors, the inaccurate traction data and vague financial metrics ('17000000' without currency) severely impact the scoring. The project falls into the 'Minimal Traction' category based on verifiable external data, despite the inflated claims in the submission.
