After her grandfather fell victim to a deepfake voice impersonating his brother, Tarini Padmanabhuni launched DetectifAI, a startup developing lightweight AI models that detect fraudulent audio in real time on smartphones.
DetectifAI operates from San Francisco and focuses on making voice authentication accessible at the device level rather than relying on cloud-based detection. The startup's models are optimized to run directly on smartphones, enabling users to instantly verify whether audio is authentic or artificially generated.
The company competes among finalists in Startup Battlefield at TechCrunch Disrupt, where emerging ventures showcase innovations to investors and industry leaders. Voice deepfakes represent a growing security threat, with scammers using synthesized audio to impersonate family members and authority figures in fraud schemes.
Padmanabhuni's personal motivation—protecting others from experiencing what her grandfather endured—positions DetectifAI in a crowded but critical market segment. Real-time detection on consumer devices could shift the balance against voice-based social engineering attacks that increasingly target elderly individuals and high-value targets.
