"It should be easier to plan when to have kids"

Grip was started by Noor (31, medical doctor), Ling (33, product manager), and Anne Marie (32, investor).

We believe it should be possible for you to make choices based on information about your body, rather than national averages. Google just isn’t good enough. We launched in the Netherlands in April 2020, grew faster than we could have possibly imagined, so then launched in the UK in 2021.

We built Grip because we wanted to understand our bodies better. Now you can, too.


“I want to have children, but being single makes that goal seem far away. I ideally want to build Grip first, anyway.”

Ling Lin

Co-founder, CPO

Ling is a co-founder and CPO at Grip. Prior to co-founding Grip, Ling was the Head of Asia Product at TransferWise. She has spent her time across North America, Asia, and Europe. She was the Chief of staff for OnePlus and Head of Risk Product of Groupon China, launching and expanding their markets globally. Ling also spent time at Amazon, improving its merchant platform.


Ling holds an MBA from INSEAD and a Master of Science/Bachelor of Science from Stevens Institute of Technology.

Ling froze her eggs in December 2020, and feels pretty good about being proactive. 


“I gave birth to a beautiful boy in October, but getting pregnant was harder than expected, and even as a doctor there was no support or information.”
