Tarini Padmanabhuni founded San Francisco startup DetectifAI to provide on-device software that identifies AI-generated voice scams. The company is currently testing its technology, having processed over 100,000 calls monthly for financial institutions in India.
Why it matters
The company targets a growing fraud landscape where Americans lost $900 million to AI-driven scams in 2025, a 24% increase from 2024. The founder launched the venture following a personal experience where her grandfather lost money to a deepfake voice scam.
DetectifAI utilizes compact AI models designed to run locally within a smartphone operating system rather than relying on cloud-based processing. The software is distributed as a development kit for integration by phone manufacturers and fraud-prevention firms.
