Michael Balaban
Michael Balaban is a software engineer and entrepreneur, a co-founder of the AI cloud computing company LambdaLambdaLambda is an American AI cloud computing company founded in 2012 by Stephen Balaban and Michael Balaban. It initially sold GPU workstations and servers for deep learning, later shifted to renting out cloud computing capacity based on Nvidia GPUs, and builds supercomputers and “AI factories” for AI training and inference.Open the full entry, who long led the company’s engineering and technology infrastructure and has served as its Chief Product Officer since May 2026.

Key facts
2012University of Michigan Graduation and Nextdoor
Balaban completed a double major in discrete mathematics and computer science at the University of Michigan, graduating in 2012, a year after his older brother Stephen Balaban. After graduating, he joined the infrastructure team of the neighborhood social network Nextdoor as a software engineer, helping scale the company’s infrastructure, particularly its news feed, from 300,000 people to 100 million, and served as principal architect of the company’s ad server engines.[1][1][1]
In 2012, he co-founded the AI computing company Lambda with Stephen Balaban.[2]
March 2015Joining Lambda Full Time
In March 2015, Balaban joined Lambda full time. He recalled that his brother had an AI background and he had an infrastructure background running large numbers of servers, and that both were interested in deep learning, so they looked through AI papers for projects to implement: based on a paper on neural network artistic style transfer, they built a website and iPhone app that turned selfies into the style of famous paintings; after they posted it on Reddit, it took off quickly, at one point drawing about 30,000 sign-ups a day.[1][1][1][1][1][1][1]
The surge in users pushed their Amazon Web Services (AWS) bill to $40,000 a month. Balaban said that after looking into it, they found that AWS machines were just ordinary hardware, so they built their own servers, about $60,000 worth of equipment that paid for itself in a month and a half; the servers were placed in a friend’s house, after which AWS handled only the front end and the bill dropped by 95%.[1][1][1]
Late 2016Shifting to Selling AI Servers
As Balaban recalled, from late 2016 into early 2017 they realized that many people working in AI were similarly burdened by high AWS costs, while the AI servers on the market were mostly pushed by salespeople who did not understand the technology; so the company began selling its own servers online, including on Amazon’s online store, and concluded that this was a better business than its original app.[1][1][1]
2020Head of Engineering
In late 2020, Balaban was head of engineering at Lambda. He argued at the time that AWS was designed mainly for e-commerce, with data centers built with extensive redundancy for high availability and low latency, whereas for AI training runs lasting several days the economic cost of a one-hour outage was limited, and data centers needed to be more concerned with the reliability of grid power; data centers focused on AI could also push power and cooling density higher, with typical cloud data centers reaching 11 to 14 kilowatts with cold aisle containment and up to 50 kilowatts with chillers in the racks.[1][1][1][1][1][1][1]
May 5, 2026Becoming Chief Product Officer
On May 5, 2026, Lambda announced a leadership reorganization in which Balaban took on the newly created role of Chief Product Officer, leading product execution to connect the company’s infrastructure to the developers and enterprises that rely on it; the company said he had scaled its technology foundation since its earliest days. On the same day, Stephen Balaban moved from CEO to CTO, and Michel Combes became CEO.[2][2][2][3]
