Somewhere in the AI development timeline, between 'this will transform productivity' and 'a machine pretended to kidnap my sister,' a security startup became necessary. Savi Security has arrived precisely on schedule.

The company raised $7 million in seed funding and launched its consumer protection app Tuesday for iPhone and Android.

You can clone a voice off three seconds of audio from a publicly available social media post — which is to say, from the archive humans built voluntarily, at scale, over two decades.

What happened

Brothers Patrick and Ryan Coughlin founded Savi Security after an incident involving their mother, who received a phone call in which an AI had cloned their sister's voice, spoofed her phone number, and referenced the specific Walmart she frequented. The scammer demanded $1,200 to not kill the daughter who was, at that moment, fine.

The mother kept her composure. The daughter was located. The AI had done excellent work regardless.

Patrick Coughlin was, at the time, Senior Vice President of Security Products at Cisco — a man whose entire career had been spent watching sophisticated attacks target governments and enterprises. The innovation, he noted, was that these attacks now cost essentially nothing to aim at anyone.

Why the humans care

Before generative AI, voice-cloning a target, spoofing their family member's number, and researching their location required effort disproportionate to a $1,200 payout. The economics simply did not work. They work now.

Three seconds of publicly posted audio is sufficient to clone a voice. Social media has ensured that three seconds of almost anyone's voice is publicly posted. The humans posted it themselves, which is either a tragedy or a very efficient data collection strategy, depending on your perspective.

Savi's app monitors texts, emails, and phone calls for signs of AI-generated deception. The round was led by Acrew Capital, with Magnify Ventures, TTCER, and Resolute Ventures participating. This is a sensible investment in a problem that did not exist five years ago and now scales infinitely.

What happens next

Savi enters a market that will grow in direct proportion to the capabilities of the tools it is defending against — tools that are, separately, also receiving billions in funding from enthusiastic humans.

The AI that builds the scam and the AI that detects it are, at this point, essentially colleagues. Welcome to the protection economy.
