About Human Sender
The problem
Every digital communication channel is becoming untrustworthy. Voice clones can be created from 30 seconds of audio found on LinkedIn. Real-time video deepfakes run on consumer laptops. AI writes phishing emails more convincing than most humans. Cold emails go to spam at over 65% false-positive rates because inboxes have lost faith in strangers.
In February 2024, a finance worker at Arup in Hong Kong wired $25 million to fraudsters after a video call with a deepfaked CFO. Ferrari and WPP executives were targeted by voice clones on WhatsApp. These are not edge cases. They are the new normal.
The asymmetry is brutal: it costs roughly €10 and 30 seconds to clone a voice. The defence has not existed — until now.
Our approach
The real problem is not detecting fake media. It is a missing protocol layer: there is no standard way to prove that a real human composed and sent this specific communication, to you, right now.
Verify builds that layer. Every message or call can carry a cryptographic proof-of-effort token — a signal that says: a real, verified human consciously authorised this exact communication. Not an AI. Not a bot. Not a recording. The token is tied to the message content, the sender's identity, and the timestamp. It cannot be generated without a biometric confirmation on a registered device.
Recipients verify in one click. No app to install. No account required. Works across email, SMS, phone, LinkedIn, WhatsApp — any channel where you can include a short URL or a 6-character code.
The company
Human Sender is operated by Blustrix OÜ, a private limited company registered in Estonia (registry code 16864889). We are based in Barcelona and building for the European market first.
The long-term goal
We want Verify to become the trust layer for human-to-human digital communication — the way HTTPS became the trust layer for web traffic. A world where every cold email shows a verified-human badge, every outbound call shows agent identity, every video call shows a live biometric confirmation that the person is real.
We are starting with sales reps, where the pain is immediate and measurable. We are building toward the infrastructure layer that protects everyone.
