Sperm Racing isn’t just a meme. It’s a $10M+ -backed startup turning male fertility into a competitive sport. In this episode of Sourcery, Eric Zhu (Founder & CEO) explains how the first race went viral with over 450M organic impressions, why sperm motility is a powerful biomarker for health, and how the company is scaling from spectacle to business.

The story has already caught the attention of 30-50M people, including some of the biggest names in culture and tech from Sam Altman, Tom Brady, Logan Paul, Theo Von, Kai Cenat, Bryan Johnson, & Justin Bieber. That kind of mainstream recognition is exactly what Eric and his team are leveraging to normalize conversations about fertility and men’s health.

From the first $1.5M race to their fresh $10M seed round led by Spartan, 9GAG, Animoca, FalconX, and Wintermute, Eric explains why reframing sperm as health could transform both wellness and entertainment.

We cover:

• Why sperm health = overall health, & how biomarker competition could become mainstream

• Going viral on $10k marketing spend and engineering cultural moments

• Turning taboo into product: supplements, at-home tests, and a global sports brand

• The future of celebrity races (Elon vs. Zuck sperm race?)
