Proof of Usefulness Score
Certified Problem Solver

DeltaStream is a legitimate, venture-backed (Series A, $25M from NEA) serverless stream processing platform that solves significant complexities in real-time data engineering (Apache Flink/Kafka). However, the submission itself is of extremely low quality, containing false claims ('most people have used my product', 'audience: everyone') and lacking technical detail. While the project's real-world utility, innovation, and actual market traction are high, the score is penalized by the misleading submission data which reduces confidence in the claimed metrics.
