Playground Global
Playground Global is an early-stage deep tech venture capital firm founded in 2015 by Andy Rubin, Bruce Leak, Matt Hershenson, and Peter Barrett, and headquartered at 380 Portage Ave, Palo Alto, California. The firm invests "somewhere between improbable and impossible," backing technical founders who take large technology risks and build companies from first principles. Playground concentrates on four pillars: next-gen compute (quantum computing, novel AI chip architectures, advanced interconnects, and semiconductors), automation (robotics, supply-chain and industrial automation with tangible ROI), energy transition and decarbonization, and engineered biology (AI-driven drug discovery, RNA editing, and next-generation therapies). It invests at the earliest stages, often at company formation, and operates Studio Palo Alto, a lab and prototyping environment for hardware and deep-science founders. Reported assets under management are over $1.2 billion across its funds. Notable portfolio companies include PsiQuantum, Relativity Space, Ultima Genomics, d-Matrix, Velo3D (NYSE), and MosaicML (acquired by Databricks).
