The Premom Story

Premom was born from a challenge that many people trying to conceive had quietly experienced for years.

Discovering the Gap

Sherry Liu and Li Zou, the founders of Premom, noticed that many people using ovulation test kits still struggled to identify their fertile window accurately. Some even taped fading test strips into notebooks, hoping to track hormone patterns by hand.

They realized that people needed a digital tool that could make fertility data easier to read, interpret, and act on—without confusion or guesswork. That realization sparked the vision for a smarter and more accessible fertility tracking solution.

Building a Solution

Sherry and Li began developing Premom in 2016. After nearly two years of research and development, the app launched as a digital fertility companion designed to help people track ovulation more effectively through intuitive tracking, test interpretation, and visual hormone insights.
