Podcast episode (Capitalism.com) featuring Ryan Danny Moran interviewing Taro Isocopola (founder/CEO of Four Sigmatic) about his entrepreneurial journey and new startup Hero (styled H I R O / pronounced “Hiro”). Covers: Four Sigmatic’s origin (started in 2012) and growth into a nine‑figure brand that helped popularize mushroom products; Hero’s mission to use fungal/mycology solutions to address plastic waste (starting with diapers); team-building, fundraising for a biotech-like venture, launch strategy (earned media, limited advertising, limited initial inventory), product claims and regulatory caution (not calling diapers compostable/biodegradable on day one), and founder work modes (grind/rest/creative) and life balance. The episode situates Hero’s longer-term vision (tens of billions in potential annual revenue) alongside near-term constraints (lab costs, validation timelines) and discusses industry headwinds (petrochemical interests, dominant diaper incumbents).
