savi security emerged from stealth with $7m in seed funding and a mobile app designed to intercept ai-generated scams, specifically voice cloning and phishing attacks. founded by brothers patrick and ryan coughlin, the technology stems from a personal incident where their mother was targeted by a deepfake kidnapping scam using a cloned voice. the company's model was tested via a free website, scam wise, which processed 50,000 submissions in four months to refine detection accuracy. this launch addresses a surge in consumer losses due to generative ai tools that allow scammers to clone voices from seconds of audio and spoof caller ids at negligible cost. by lowering the barrier to entry for these sophisticated attacks, cybercriminals have shifted focus from enterprises to everyday individuals, a trend savi intends to reverse with real-time intervention.
