About hCaptcha

Privacy, Security, and Machine Learning.

hCaptcha is the world's most widely used independent CAPTCHA service.

Privacy Focused

hCaptcha brings a modern, privacy-focused approach to stopping bots.

Our systems are thus designed from the ground up to minimize data collection and retention while maintaining class-leading security. The best way to protect user data is not to store it at all.

Security First

Bad actors are increasingly common online. But sacrificing user privacy is not the answer.

Security solutions offered by ad companies focus primarily on tracking users across the web. We have created an effective security solution that proves harming user privacy is not necessary to deliver excellent results.

Who we are

An experienced team, working on today's hardest problems. hCaptcha is a service of Intuition Machines.

With decades of software and ML expertise, we build and operate massively scalable systems to tackle some of today's hardest problems while preserving privacy.

We specialize in deep learning and visual domain machine learning at scale, with a particular focus on securing online systems from sophisticated modern threats.
