Fertility Tech Startups funded by Y Combinator (YC) 2026

We are making a new fertility treatment that infertile couples can order with a click of a button to help them conceive at home. Our technology increases the likelihood of pregnancy by guiding significantly higher number of sperms towards the ovum using a proprietary combination of surface features and microenvironment optimization. The fertility treatments available today, such as in-vitro fertilization (IVF) and intra-uterine insemination (IUI), are psychologically and financially draining and come with considerable treatment-associated risks. Furthermore, over 25 million women of reproductive age in the US have limited nearby access to fertility treatment.
