Why Callstrike?

The deepfake threat didn't emerge overnight. From breakthrough innovation to weaponized attacks, wetraced the evolution—and recognized what enterprises lacked: a purpose-built platform to simulatedeepfake phishing attacks, train employees against voice and video manipulation, and build organizationalresilience before the real attack happens.

Google Duplex Demo at Google I/O

Sundar Pichai demonstrates AI making autonomous phone calls to humans. The security implications are immediate: voice-based social engineering just became scalable, automated, and virtually undetectable. The era of weaponized voice AI begins.

Democratization of Deepfake Technology

Open-source projects like FaceSwap, DeepFaceLab, and voice changers RVC and So-VITS-SVC amass over 100k GitHub stars and millions of downloads. Voice cloning now requires just 3 seconds of audio. Face swapping works in real-time. The barrier to launching sophisticated deepfake attacks drops to near-zero.

Deepfake Phishing Goes Mainstream

Google Trends data shows 'deepfake' and 'voice phishing' searches skyrocket as real world attacks accelerate. CFOs fall for cloned voices authorizing wire transfers. Executives are impersonated on live calls. CrowdStrike reports vishing attacks increased 442% in 2024.

VC Funding Surge & Rising Threats

Andreessen Horowitz, Greylock, OpenAI ecosystem investors, and other top firms pour millions into deepfake and voice AI companies— mostly targeting content creation, entertainment, and detection. Meanwhile, deepfake-enabled attacks drain millions from enterprises. The funding flows everywhere except where it's needed: enterprise-grade offensive security simulation and training.

Training That Matches the Threat

Enterprises lacked a deepfake-specific phishing simulation and training platform. Legacy vendors and funded startups bolted basic voice capabilities onto existing tools—simple API wrappers around ElevenLabs, PlayHT, and Resemble AI. Callstrike was built differently: purpose-engineered for live voice impersonation, callback phishing, deepfake video conferencing, and adaptive training. The first platform designed specifically to simulate the attacks enterprises are already facing.
