Cerebras Systems, now valued at $60 billion after its recent IPO, nearly faced collapse in 2019, burning through $8 million monthly while tackling a seemingly insurmountable technical issue. The company, which sells AI chips to major players like OpenAI and AWS, was founded on a bold vision to revolutionize chip design.
Vision and Early Struggles
Founded on the idea of turning a whole silicon wafer into a single, powerful chip, Cerebras aimed to solve the AI industry's need for increased compute power. “We were spending about $8 million a month,” CEO Andrew Feldman told TechCrunch, as they tried to overcome a technical problem nobody in the semiconductor sector had solved before. By 2019, nearly $200 million had been spent in this pursuit.
Feldman regularly faced the daunting task of reporting these failures to the board. Despite the challenges, he persisted knowing that without a solution, the company was doomed.
The Technical Challenge
The team's ambition involved creating a chip 58 times larger and using 40 times more power than existing technologies. After succeeding in designing and manufacturing the mega chip with TSMC, Cerebras hit a major roadblock in 'packaging'—the process of integrating the chip with a motherboard, including power, cooling, and data management. Without solving packaging, the chip was useless.
Through trial and error, and after destroying an enormous number of chips, the team finally overcame these challenges. They even invented a machine capable of securing the wafer to a board with 40 screws simultaneously.
Breakthrough and Success
July 2019 marked a turning point when Cerebras successfully installed and ran the packaged chip, a moment Feldman describes as one of the greatest in his life. This milestone came two years after talks with OpenAI about a potential acquisition fell through due to internal disputes at OpenAI, where several founders are also Cerebras investors.
OpenAI, now a partner and customer, provided Cerebras with a $1 billion loan secured by warrants for 33 million shares, valued at over $9 billion at the recent closing price. The agreement includes a temporary restriction on selling to specific OpenAI competitors.
Strategic Focus and Future Plans
Feldman emphasized a strategic focus on managing growth, likening it to an all-you-can-eat buffet. “We’re going to work with part of the buffet only, and we’re going to get comfortable with that, before we attack the rest,” he explained, highlighting the company's measured approach to scaling its AI compute capacity.
Cerebras’ journey from the brink of failure to a $60 billion valuation underscores the potential of breakthrough innovation in overcoming seemingly insurmountable challenges.
