Our Methodology
"Consent isn't paperwork. It is a shared sensation — a moment in which two human beings have agreed to exist in the same reality, with the same enthusiasm."
In Consent Codes, Stef Hammett exposes the hidden operating system shaping how power, desire, and dignity actually work — in bedrooms, boardrooms, and courtrooms. The framework behind everything we build at HMS.
Your consent code is as unique as your fingerprint. Personal. Contextual. Yours.

Nerd out with us
The lifetime economic burden of r*** per victim. This is what we're working to prevent — through infrastructure, not just education.
Peterson, DeGue, Florence, Lokey. "Lifetime Economic Burden of Rape Among U.S. Adults." American Journal of Preventive Medicine 52(6):691-701 (2017). CDC.
Each case carries more than $122K in lifetime costs — absorbed by families, campuses, workplaces, and communities. The CDC estimates a $3.1 trillion total lifetime economic burden, adjusted to over $4 trillion today.
Consent is not a soft topic. It is a line item we're all funding, whether we choose to talk about it or not.
