REAL STORIES
Women Who Feel Safer Every Day
"I feel so much safer walking to my car"
I work late shifts and always felt nervous in the parking garage. Sirenz clips right onto my keys and I know I have something loud if I ever need it.
"Bought one for me and my daughter"
My daughter just started college and I wanted her to have something practical. Sirenz is easy to use and it's actually loud.
"Perfect for solo runs"
I run early mornings alone and always felt uneasy. And now because I have Sirenz with me it gives me more confidence. I'd never run without it now.
WHY WE STARTED SIRENZ
A Night Out That Changed Everything
In 2025, someone close to us was groped by two strangers on her way home after a night out. She was alone. It happened fast. And there was nothing she could have used in that moment to make herself heard, to stop it, or to get help.
That helplessness stayed with us. Not just as anger — but as a question we couldn't let go of: why is there nothing simple, reliable, and immediate that a woman can carry to protect herself?
That question is why Sirenz exists. We built it for her. And for every woman who has ever felt unsafe walking to her car, running alone, or simply getting home.
THE REALITY
1 in 3 Women Will Experience It
According to the CDC, 1 in 3 women in the United States experiences sexual violence, physical violence, or stalking by an intimate partner in her lifetime. That number doesn't even include strangers.
81% of women have experienced some form of sexual harassment or assault. Most of them were alone when it happened. Most of them had no way to respond fast enough.
These aren't just statistics. They are daughters, sisters, friends, and mothers. They deserve something better than being told to "be careful."
