What we're doing
We aim to change the outdated view that fertility is a "women's issue" by creating an accessible, affordable product for men & people with sperm. This includes everything from a mail-in kit for sperm testing & sperm freezing, personalized sperm improvement products, tele-health, DNA fragmentation analysis, supplements, and more.
Why are we the leader?
The company was founded at Harvard by a team of healthcare and fertility experts. We obsess about talent density and have out-executed our competitors over the past few years. Beyond our D2C channel, we've also unlocked:
1. Nationwide insurance coverage (10M+ lives)
2. Military contracts (Including the Navy SEALs and 15M+ veterans)
3. Employer offerings (Working with the top fertility benefit providers)

Is this you?
If you're behind Legacy: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. GetFoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.
