Taika
Taika is a San Francisco-based functional beverage company making ready-to-drink canned coffees and matcha lattes infused with adaptogens and functional mushrooms - ingredients like L-theanine, ashwagandha, and lion's mane - meant to deliver focused energy without the jitters or crash. Founded in 2019 by former Facebook engineer Michael Sharon and world-class barista Kalle Freese, the brand is plant-based and sweetened with monk fruit for zero added sugar. Its tagline, 'Feel Inspired, Not Wired,' captures the pitch: caffeine with calm, sold direct-to-consumer online and through retail.
Magic Mind
Magic Mind makes a 2-ounce 'mental performance shot' built from a blend of around a dozen nootropics, adaptogens, vitamins and antioxidants - think lion's mane, ashwagandha, L-theanine and ceremonial matcha - designed to deliver calm focus without the jitter-and-crash cycle of a big cup of coffee. Founded in 2020 by James Beshara and William Hicks, the brand started in a San Jose commercial kitchen, grew through direct-to-consumer subscriptions, and has since pushed into national retail including Whole Foods, Erewhon, Sprouts and Albertsons. It raised a $12.4M Series A in September 2025.
