Thesis

Backs frontier deep tech companies solving physical infrastructure bottlenecks of the AI supercycle, especially compute, energy, quantum, AI infrastructure, robotics, and autonomous manufacturing across the U.S.-Israel corridor.

Likely not a fit for

Generic AI applications, commoditized SaaS, consumer products, kinetic battlefield-only defense products, and science projects without credible commercialization or infrastructure-scale demand.

Caruso Ventures$500K–$2.5M

Invests in Colorado deep-tech scaleups—especially quantum and space—via deal-by-deal SPVs letting outside co-investors join his proprietary deal flow and access Dan Caruso's experience building three $10B+ telecom companies. Founded and led by Dan Caruso, who built three $10B+ telecom infrastructure companies and now invests almost exclusively via deal-by-deal SPVs rather than a traditional commingled fund, allowing outside co-investors to selectively join his proprietary deal flow in specific Colorado tech companies. The fund focuses heavily on Colorado "deep tech" scaleups with an outsize emphasis on quantum technology and space tech, maintaining a portfolio unusually concentrated in frontier/critical infrastructure assets like quantum computing, advanced space propulsion, and supersonic aircraft rather than typical SaaS companies.

ACME Capital$500K–$15M
DCVC$5M–$25M

Targets companies applying modern computation (AI, simulation) to agriculture, mining, manufacturing, health and defense, leveraging partners's hard-science and national-security expertise to navigate regulation and dual-use challenges.

1517 Fund$50K–$1M

1517 Fund is an "anti-establishment educational institution" that backs "dropouts, renegades, and sci-fi scientists" with a strong preference for founders without undergraduate degrees and deep-tech researchers working on ideas that would appear in science fiction. They operate as "the first believer" in companies at extreme inception, providing $50k-100k R&D checks before non-dilutive grants and running a pre-VC pipeline including micro-grants for weird projects, teen camps, and a 3,000+ hacker community they often know for years before writing checks.
