Gretel.ai, a platform that allows engineers to "create anonymized, synthetic data sets based on their actual data sets," secured $50 million in Series B funding, TechCrunch reports. The use of synthetic data sets may eliminate the risk of a data breach exposing personal information. "Gretel gives data teams working in any framework or language the tools they need to build privacy by design into their existing workflows and data pipelines, greatly simplifying this process," Greylock Partner Sridhar Ramaswamy said.
