Proof of Usefulness Score
Category Standard

Tessian is a major success story in the cybersecurity space, having been acquired by Proofpoint in late 2023 for an estimated $400M-$500M. The project demonstrates exceptional real-world utility and verified traction (Series C valuation of $500M). However, the specific submission provided contains hyperbolic and inaccurate claims regarding audience reach (e.g., 'most people have used my product' for a B2B tool) and lacks detail in the description. While the underlying project is a high-value 'Large Scale' entity, the score is adjusted downward due to the low quality of the submission text.
