Sifflet

Sifflet is a legitimate, Series B funded Data Observability platform (founded 2021, raised ~$58M) with significant enterprise traction (e.g., Carrefour, Penguin Random House). However, the submission quality is critically low, containing demonstrably false claims (e.g., 'most people have used my product', 'team size 1-10', target audience 'everyone') and lacking specific data. While the project's real-world utility and verified market position are high, the score is heavily penalized by the poor quality of the input data.
