Mei Z.

The enigmatic angel investor known as "Matrix Multiplication" (Mei Z.) has emerged as a significant force in the AI and deep tech investment space. With an aggressive and diversified portfolio spanning some of the most promising AI startups, Mei Z. is shaping the future of artificial general intelligence (AGI) and machine learning.

Mei Z. is not just another name in venture capital; they are a strategic investor with a clear vision: accelerating the development of AGI. With investments in companies like AGI Inc, Stability AI, EleutherAI, and MultiOn, Mei Z. is funding projects that are at the forefront of large-scale AI training, model optimization, and synthetic intelligence. The focus on foundational AI models, from GPT-NeoX to VQGAN-CLIP, highlights a commitment to pushing the boundaries of machine cognition.

Beyond AI model research, Mei Z. has also backed startups in compute infrastructure (San Francisco Compute Company, Etched), biotech (Pangea Bio, Circle Labs Bio, Radar Therapeutics), and automation (MultiOn, ComfyUI, FlyMy.AI). This diverse portfolio suggests an understanding that AI breakthroughs are deeply interconnected with computational power, biological intelligence, and automation technologies.

Mei Z.'s expertise extends beyond investment. As an advisor to EleutherAI, one of the most respected open AI research organizations, they are directly involved in shaping AI model training and dataset curation. Their association with MIT, even as a dropout, further cements their credibility as a technologist-investor hybrid.

Their background in Lisp—one of the oldest and most flexible programming languages for AI—indicates a strong foundation in computer science. Additionally, their past research at the MIT Media Lab suggests hands-on experience in machine learning and computational creativity.

One of the most intriguing aspects of Mei Z.’s vision is their belief in an AGI timeline of 2027. Unlike many investors who approach AGI with skepticism, Mei Z. actively funds projects that aim to make it a reality within the decade. By investing in Extropic, Standard Intelligence, LogicStar AI, and Nolano AI, they are placing calculated bets on companies pioneering advancements in self-improving algorithms, reinforcement learning, and neuromorphic computing.

Mei Z.’s ability to invest in so many high-impact startups—especially those that require extensive computational resources—suggests strong connections within the tech and research community. Their former board position at UCSF Health Hub and tenure at Romulus Capital (a firm known for backing early-stage deep tech startups) showcase their deep network within both academia and venture capital.

Mei Z. is not just an angel investor; they are a catalyst for the next wave of AI innovation. Their investments reflect a long-term vision where AGI is not just a theoretical milestone but an inevitable reality. While many investors hedge their bets across multiple industries, Mei Z. appears to be making a concentrated effort to fund the infrastructure, intelligence, and compute necessary for artificial superintelligence. If their vision aligns with reality, they may very well be one of the most consequential investors of this AI revolution.
