The submission appears to be a personal portfolio or contracting entity for a Senior iOS Engineer rather than a scalable technology product. While the individual (Panagiotis Sartzetakis) has verified high-level experience with major clients (Calm, Soho House, Vodafone) and a registered UK company active since 2016, the submission itself relies on hyperbolic claims (e.g., 'most people have used my product') which refer to client work rather than the project entity. The 'marketcap' figure likely represents lifetime contracting revenue. As a service business, it lacks the scalability of a tech product, resulting in a lower PoU score despite the legitimacy of the engineer's career.
