Share Ventures

Share Ventures is a Culver City, California-based venture studio and early-stage investor founded in 2020 by Hamet A. Watt — MoviePass co-founder and former partner at Upfront Ventures. The firm operates at the intersection of human performance and artificial intelligence, combining an in-house ideation and incubation lab with an investment fund. Most portfolio companies are co-founded and incubated internally rather than sourced externally, giving Share Ventures deep operational involvement from day one. Strategic LPs and backers include True Ventures, Upfront Ventures, Alpha Edison, Google, and Amazon, who collectively supported the firm's approximately $10 million core studio vehicle. Share Ventures leads rounds and writes initial checks from pre-seed through seed, with the investment thesis centered on brain health, cognition, sleep and recovery, longevity, AI-powered consumer wellness, and new human-information interfaces. The portfolio of approximately five companies reflects the studio's focus: Jocasta Neurosciences, a longevity-protein program for cognitive impairment that raised a $35 million Series A led by True Ventures in August 2025; Feno, an AI-powered smart toothbrush for oral health that raised $6 million at seed in 2024; and Grand Slam Track, Michael Johnson's professional track league. William Litvack serves as Principal alongside founder Watt. Share Ventures occupies an intentionally narrow thesis in a broad wellness market, concentrating on the biological and technological frontier of human performance rather than commodity consumer health. The studio model means founders benefit from Watt's operator network and the firm's in-house product capabilities before external capital rounds are even assembled.
