What Jetstream does
Jetstream is a privately held, San Francisco-based pre-seed venture capital fund founded in 2019 by Tommy Leep, a Stanford graduate and Silicon Valley native who previously served as the first hire at Floodgate and held roles at Haystack, AngelList, and Congruent Ventures. The fund invests at the pre-seed stage in startups whose missions align with helping people live healthier, wealthier, and more resilient lives, with a portfolio of 50+ companies spanning climate technology, fintech, health, disaster recovery, EV charging, and the space and air economy. Jetstream positions itself around fast decision-making, founder accessibility, and follow-on funding support.
The fund's core product is a single investment vehicle that pairs early capital with structured community support: portfolio founders gain access to a 20+ person advisor network drawn from senior investors at Google, OpenAI, CRV, True Ventures, Haystack, Village Global, Maveron, Obvious Ventures, Footwork, Prelude Ventures, Spero Ventures, Toba Capital, Cantos, Halogen, Soundcheck, Streetlife Ventures, Angel Collective, Neo, and Swimming With Allocators for customer introductions, strategic guidance, and coordination on subsequent financing rounds. Notable portfolio holdings include Mercury (fintech), Presto (EV charging), Bright Harbor (disaster recovery), Electric Plant Co (plant intelligence), and Immortal (health).
Economically, Jetstream operates as a small, principal-led fund with 1-10 employees and no disclosed fund size, limited partners, AUM, or revenue. Returns are generated through equity ownership in portfolio companies, realized via follow-on rounds, acquisitions, or IPOs, with management fees providing baseline operating revenue. There is no public app, API, software product, or proprietary technology platform; the asset under management and customer concentration are not disclosed, and the firm has signaled thematic expansion into the space and air economy via a disclosed interest in Shield AI.
