Playground Global: Where Deep Tech Gets Its Start — With a 70,000 Sq-Ft Lab to Prove It

Playground Global is, in its own words, "where deep tech gets its start." The Palo Alto firm, founded in 2015, invests at the earliest stages of company formation, backing technical founders at the intersection of AI, engineered biology, next-generation compute, and hard science — on the belief that breakthroughs in science and engineering, not just software, will create the next generation of valuable companies.

Sector focus is explicit: next-gen compute (quantum, AI acceleration), automation, the energy transition, and engineered biology. The firm invests at seed and Series A, writing initial cheques of $1M–$20M and often leading the round. It is a generalist about ambition and a specialist about technical depth: the partners are engineers and operators who evaluate science as well as markets.

Fund size is publicly stated. Playground Global's Fund III closed at $410 million in December 2023, which at the time brought total assets under management to over $1.2 billion. A newer $475 million fund for seed and Series A deep-tech investing was reported as recently closed in mid-2026.

The portfolio is a showcase of technical ambition, all named on the firm's own site. PsiQuantum is building fault-tolerant quantum computing; d-Matrix makes AI inference hardware using in-memory compute for data centres; Agility Robotics builds humanoid and legged warehouse robots; MosaicML, an AI model training platform, was acquired by Databricks for $1.3 billion; Velo3D does metal 3D printing for aerospace; Ultima Genomics is building next-generation genome sequencing; Manifold Bio combines AI with in-vivo protein engineering for therapeutics; and Strand Therapeutics is developing programmable mRNA therapeutics.

The partnership reflects the firm's technical bent. Co-founders Peter Barrett and Bruce Leak lead as general partners, alongside Jory Bell, Matt Hershenson, and Laurie Yoler. Pat Gelsinger, the former Intel and VMware CEO, joined as general partner with a semiconductors focus in 2025, and Benjamin Kim is a partner.

Playground runs no formal fellowship or accelerator — instead it operates a venture studio and lab: a roughly 70,000 sq-ft Palo Alto facility housing portfolio companies and adjacent deep-tech start-ups, with hands-on technical and engineering support for founders building hard things. No formal founder credit or perks programme is publicly stated.
