Bright Machines Hybrid BRC targets AI server assembly bottlenecks
Bright Machines says its Hybrid BRC keeps manual assembly inside tracked robotic cells as AI server makers chase better yields.

Bright Machines announced the Bright Machines Hybrid BRC, a new robotic cell for AI server manufacturing that lets human operators perform defined assembly tasks inside a monitored production station. The San Francisco company says the product is meant to preserve the digital build record for each server when automation has to give way to manual work, a quality problem that matters as hyperscalers push for faster AI infrastructure deployment.
The Hybrid BRC expands Bright Machines’ Bright Factory platform. According to the company, guarded doors and safety panels let a worker enter the cell; opening the doors shuts down the robotic arm while screens guide the operator through the required steps. Cameras, force feedback and tooling sensors continue checking for wrong parts, missed steps and incorrect installations, with traceability maintained at the serial-number level.
What is the Bright Machines Hybrid BRC?
The Hybrid BRC is a production cell that combines robotic assembly with monitored manual intervention. Its purpose is to keep human work inside the same data environment as automated work, rather than moving partly built servers to an offline bench where quality data can be lost.
CEO Sviat Dulianinov said the yield difference is the core reason for the design. He said first-pass yield for manual AI server assembly can start as low as 20% and later improve to roughly 60% to 65%. By comparison, he said Bright Machines’ robotic operations usually exceed 98% yield at the station level and reach about 97.5% to 97.7% at the line level.
Those figures are company claims, but they point to the economic issue Bright Machines is selling against: AI servers can cost hundreds of thousands of dollars, and rework slows deployment of expensive compute. Dulianinov said the company prefers to begin with at least 50% automation and move toward at least 80%, adding that robotic lines can be 50% to 100% faster than human operations in throughput terms.
Why does AI server assembly matter now?
AI infrastructure delays are often discussed in terms of GPU supply, power and data center construction. Bright Machines argues that turning chips and boards into tested, deployable servers is another constraint. Dulianinov said that when chips, motherboards, power and buildings are available, assembly and testing can still take months, and claimed Bright Machines’ technology can reduce that timeline by at least one-third.
The company has not named the customers using the hybrid lines. Dulianinov said customer secrecy is tied to data center intellectual property. He did say Bright Machines is already running hybrid lines in the U.S. and has built more than 10,000 compute nodes through the new stations. The company also says it plans to manufacture more than half a gigawatt of compute capacity this year.
Bright Machines disclosed broader operating metrics as well: more than 130 microfactories deployed across more than 10 countries, more than 60 customers served and more than 300,000 servers produced. It said customer count grew more than 3x this year versus last year and that it is moving from San Francisco’s 16th Street to a Burlingame site executives described as three to four times larger. Revenue was not disclosed.
Dulianinov positioned Bright Machines against both software vendors and contract manufacturers. He described Tulip as focused on operator interfaces and Instrumental as focused on inspection, while arguing Bright Machines runs the full production operation. He said the more relevant comparison is with Flex, Jabil and Foxconn, though he argued those manufacturers have historically depended more heavily on manual labor with less production data.
Bright Machines was spun out of Flex eight years ago. The Wall Street Journal and CFO Dive reported in 2021 that the company planned a SPAC merger at a reported $1.6 billion valuation before that deal collapsed. In June 2024, Bright Machines announced a $126 million Series C, including $106 million in equity led by funds managed by BlackRock and $20 million in venture debt from J.P. Morgan, bringing total capital raised to more than $400 million, according to the company.
