About Stealth1000
Ali Sina is the founder and CEO. Sources give three different start years: a 2017 press release and a 2017 profile say 2017, the firm's homepage says 2018, and its story page says it was founded in 2019 as a fund. The story page says the firm began as a fund, later added an incubator, and now runs both under one partnership. A 2017 press release places the firm in Irvine, while one PitchBook profile lists Los Angeles. The firm's own site says it has a network of 600+ companies, and its portfolio page lists 19 operating companies and 600+ in its pipeline.
The firm says it writes first checks into AI-native founders building companies it describes as category-defining, and its site says every check since a later turning point has been AI-first. In 2025 it joined the NVIDIA VC Alliance, an invitation-only group of venture investors. Its current investment theses listed on the fellowship page include AI infrastructure for vertical SaaS, healthcare workflow automation and education technology. Its portfolio page lists AI companies such as Academy, an AI-era education program, and Agro, which sells vertical AI software to mid-size farms.
The firm's homepage says it invests from pre-seed through Series A. Its fellowship program takes a 30 to 50 percent stake before Series A and wires $150K of personal runway capital to the founder on day one. That amount is founder living and validation money, not an investment check size. The firm has not published fund sizes or typical check sizes.
