Diamfab is a legitimate deep-tech spinoff from CNRS (France) specializing in synthetic diamond semiconductors, having raised ~€8.7M (Series A) in 2024. However, the submission quality is critically low, containing demonstrably false claims (e.g., 'most people have used my product', 'audience reach: everyone') and inaccurate data (team size claimed 125, likely <30). While the technology scores high on innovation and potential utility in the EV/energy sectors, the lack of current commercial reach and the deceptive submission details heavily penalize the final score, placing it in the 'Minimal Traction' category despite its funding success.
