DroneTector

The founding team is legitimately exceptional — Moore's PhD was literally on millimetre-wave radar for drone detection, which is almost perfectly on-the-nose for this product, and Doherty adds serious physics depth. The market is real, urgent, and government-backed globally. However, there is zero visible product evidence: no specs, no deployments, no customers, no revenue signals, and the website is barely functional. They're backed by YC, NATO DIANA, and RAEng which suggests institutional validation, but DroneTector needs to show hardware in the field and paying customers before this moves to A-tier. The key question is whether they've shipped real radar hardware or are still in lab/prototype phase.
