Emeryville startup Atomic Machines emerges from stealth with $250 million funding as Ratio Innovation Campus sells for $63.5 million

Emeryville's industrial and research corridor recorded two major capital milestones this weekend as advanced hardware startup Atomic Machines emerged from six years in stealth mode with $250 million in venture funding while the nearby Ratio Innovation Campus traded hands for $63.5 million. Founded by former Amazon and Uber executive Jeff Holden, Atomic Machines plans to hire for dozens of engineering and advanced manufacturing positions at its new East Bay facility. Every municipal economic development official in Emeryville, Oakland, and Berkeley welcomed the expansion as a catalyst for deep-tech job growth.

Atomic Machines has engineered an artificial intelligence-driven micro-manufacturing platform called the Matter Compiler, which converts digital blueprints directly into miniature electromechanical machines containing moving parts and multiple materials. Alongside its platform debut, the company unveiled its first commercial product, PrimeSwitch, a high-speed electrical relay built for 800-volt power distribution architectures inside hyperscale AI data centers. Company engineers noted that future roadmap applications for the Matter Compiler program include microscopic medical robotics and high-density semiconductor chip cooling systems.

Blocks away in the same Emeryville research district, New York-based investors linked to life sciences real estate specialist Outshine Properties acquired the 241,000-square-foot Ratio Innovation Campus spanning 6401 Hollis Street and 1480 64th Street. Property records show the $63.5 million purchase price represents a roughly 51 percent discount below the $129.5 million paid by previous owner Beacon Capital Partners in 2020. Beacon had also invested $24 million during 2022 into lobby and laboratory upgrades across the campus, which currently sits 71 percent leased amid elevated East Bay life sciences vacancy rates.

Commercial brokers and planning commission analysts across Alameda County and Contra Costa County observed that repriced laboratory buildings are increasingly attracting hardware, clean-tech, and robotics firms priced out of San Francisco and Silicon Valley. Commuters traveling from Walnut Creek, Lafayette, Orinda, and Concord benefit from Emeryville's proximity to Interstate 80 and Amtrak Capitol Corridor rail links. Meanwhile, the Emeryville City Council and county workforce development board continue coordinating local industrial zoning and STEM training grant programs with nearby community colleges.

Engineers, fabricators, and commercial tenants can review open technical positions at atomicmachines.com or contact the City of Emeryville Community Development Department regarding business permitting at (510) 596-4300. Inquiries concerning laboratory leasing at 6401 Hollis Street may be directed to the Ratio Innovation Campus management office Monday through Friday between 8:30 AM and 5:30 PM. Additional municipal briefings on East Bay research corridor occupancy trends are scheduled for November.
