About Feanix Bio

Feanix is rebuilding animal breeding from the genome up.

We’re a YC-backed startup using whole-genome sequencing and custom ML models to help dairy farmers make better breeding and herd management decisions.

Our technology is genuinely novel: we can sequence a full genome from a single hair at a fraction of traditional industry costs, our models achieve ~90% prediction accuracy on traits where existing approaches sit closer to ~30%, and we’re pioneering farm-specific genomic predictions that turn genetics into practical, actionable decisions.

That technology is translating into real adoption. In a short time, we’ve grown to serve roughly 1% of the U.S. dairy industry — and reached $10M+ in ARR, with significant demand still ahead of us. We’re backed by Initialized Capital, General Catalyst, Collaborative Fund, Overwater Ventures, North South Ventures, and Y Combinator.

We started with dairy because our founders grew up on dairy farms and understand firsthand the problems we’re solving. But genetics is foundational to every agricultural industry, and dairy is only the beginning.

We’re building Feanix with a small, high-caliber team where people have meaningful ownership and work end to end. There are no unnecessary layers and very little room for busywork — just difficult problems at the intersection of biology, data, and software that haven’t been solved before.

If you’re exceptional at what you do and want your work to have a measurable impact on an entire industry, we’d love to build it with you.

About The Role

Customer Success is our post-sales organization: customer success, support, onboarding, and delivery operations run as one function. You'll lead it, owning every customer relationship from signed contract through launch, steady-state use, and renewal.
