About

Why we build.

Shir Shani

Shir Shani

Co-founder & CEO

Kuki Aviran

Kuki Aviran

Co-founder & CPO

Shir spent six years on the pill. When she stopped, she wanted her cycle back without another hormone.

She tracked fertility by hand. It worked, but asked too much of real life. With Kuki, that search became Meri.

Now they're building it for women everywhere.

Questions & answers

Product

What is Meri?
A night sensor and an app. Wear it to sleep. By morning you know where you are in your cycle, and whether you can get pregnant that day.
Is Meri a contraceptive?
Meri is a fertility monitor, like Daysy or Tempdrop. It shows your fertile window. It does not prevent pregnancy on its own.
Why temperature?
After ovulation, resting temperature rises. Meri reads that overnight so you don’t need a fragile morning reading.
How do the patches work?
Medical-grade adhesive holds the reusable heart sensor to your skin overnight. Fresh patches ship with membership.
