Announcing Nucleus Embryo
Genetic optimization is here.
Nucleus is excited to announce the launch of Nucleus Embryo, the first genetic optimization software that helps parents pursuing IVF see and understand the complete genetic profile of each of their embryos.
This is more than a milestone on our roadmap. Nucleus was never just for individuals to understand their health: I’ve long envisioned genomic medicine that spans generations.
My parents are immigrants from Iran who came to America with nothing but a conviction that me and my siblings would have more. But when my 15-year-old cousin suddenly died in her sleep from a preventable genetic disease, my family was powerless to save her.
My parents, grieving the loss of my cousin, were also terrified. What if my siblings and I were at the same risk? That was the first time I understood what generational health meant.
Our users don’t just do Nucleus for themselves — they do it for themselves and their loved ones. Now, I’m proud to say that care can start before a child is even born.
Nucleus launched a year ago with 12 analyses. Our earliest users were those who already knew the promise that genetics holds for the future of health. We kept building to bring the vision we shared with them to fruition.
Soon after launch, we’d doubled the number of analyses. Then we 10x’d them. By the spring, we’d added over 900 diseases — including the one my cousin died from. Months later, we launched genetic matching to help parents understand hidden risks they could pass down to their children.
With the launch of genetic matching, parents started asking us a new question: What else can I know about my future child?
We launched Nucleus Embryo for parents who want to know more — so Nucleus is built for longevity at every stage of life. Nucleus Embryo enables parents undergoing IVF to analyze and compare up to 20 embryos across over 900 hereditary conditions and 40 additional analyses beyond basic viability, spanning cancers, chronic conditions, appearance, cognitive ability, mental health, and more.
But longevity was never just about health. It’s about thriving. That’s why this announcement also marks the first time in human history a company has openly partnered with a couple to help them optimize their embryos based on intelligence. You can read part of their story below.
I started Nucleus because I believe in the power of genomics to make life better. That belief hasn’t changed — but the science has. What is possible today wasn’t even possible five years ago.
I see a world where sequencing, analyzing, and editing DNA merge seamlessly to create a truly preventative health care system.
To our early Embryo users: thank you for trusting us with one of the most meaningful choices of your life. You helped shape this product. You asked hard questions. We built this tool for you.
One more thing. Some people don’t think you should have access to the choice Nucleus Embryo empowers you to make.
Here’s the thing. It’s not their choice to make.
It’s yours.
