Gretel (formerly Gretel.ai) was a San Diego-based multimodal synthetic data platform that let developers generate privacy-preserving, artificial datasets to train and test AI/ML models without exposing real sensitive data. It raised $65.5M across seed, Series A, and Series B rounds before being acquired by NVIDIA in March 2025 for a reported $320M+; the standalone product is now discontinued, with the technology folded into NVIDIA NeMo Data Designer and Safe Synthesizer.
