Founders

Ara Katz
Co-Founder, Co-CEO
A serial entrepreneur, Ara Katz has worked at the intersection of tech, media, and design. Her pregnancy and breastfeeding experience inspired a personal mission to explore the importance of microbes and how they will impact the health of our bodies, our children, and our environment. At Seed Health, she leads fundraising, design thinking, brand, insights, commercialization, and the company’s translational work in science communication and storytelling. Ara is also a co-founder of Seed Health’s environmental initiative, SeedLabs, and its first therapeutics partner company, LUCA Biologics.
Previously, Ara co-founded mobile commerce startup Spring, where she helped launch ApplePay on iPhone. As an advisor across companies in health tech, ed tech, consumer, and sustainability, Ara has invested in RXDefine, Newness, C16 Biosciences, MindBodyGreen, Mahmee Maternal Care, Stadium Goods, and Unicycle.
Ara was a fellow at the MIT Media Lab’s Center for Future Storytelling and CCA’s Design Thinking MBA program, and has been named in Marie Claire’s ‘The New Guard: The 50 Most Influential Women in America,’ Business Insider’s Silicon Alley ‘Top 100’ and ‘36 Rockstar Women in NYC Tech,’ and Create + Cultivate’s ‘100 List for STEM.’ Her work has been featured in Fast Company, TIME’s Best Inventions 2018, Forbes, TechCrunch, CNBC’s Upstart 100, Barron’s, CNN Business, and The Wall Street Journal.
She lives in Venice, California with her husband and five-year-old son, Pax (the reason Seed Health exists). She is passionate about the communication of science, the interplay of the environment and physical space, and the connecting of never before connected dots. Oh, and she’s the proud owner of several tardigrades who now live at Harvard’s Museum of Natural History.
