Helping parents meet their baby sooner
The wait to know your baby's gender shouldn't feel endless. NubHub gives expecting parents a careful, human-checked early prediction from the 12-week scan they already have — just for fun, months before the 20-week reveal.

Why we started
It started with a simple frustration: waiting until the 20-week scan to find out if we were having a boy or a girl felt like an eternity. After our 12-week scan, we discovered nub theory and realised there was an evidence-backed way to get an early glimpse.
But finding clear information and a careful reading was hard. So we built a service that pairs an AI nub reading with a human double-check — and is honest that it is an early, for-fun estimate, not a medical test.
Today we help expecting parents get an early peek at their little one — every nub prediction backed by our 100% money-back guarantee, because we believe in what we do.
