Cerebras Systems, now a public company valued at around $60 billion, faced near-collapse in 2019 when it burned $8 million per month trying to solve unprecedented technical challenges.

Founded to create a single massive AI chip by using an entire silicon wafer, Cerebras tackled a problem that had defeated the semiconductor industry for decades.CEO Andrew Feldman recalls the company had spent nearly $200 million without a functioning chip, repeatedly reporting failures to the board.

Key obstacles involved packaging, cooling, and data transfer for a chip 58 times larger than typical designs, requiring enormous power and custom-built solutions.The breakthrough came after inventing specialized machinery and meticulous trial-and-error testing.This success enabled Cerebras to serve major AI clients like OpenAI and AWS.Notably, OpenAI provided a $1 billion loan secured by warrants, granting conditional rights to over 33 million shares.The company also agreed temporarily not to sell to certain competitors.

Despite its rocky early years, Cerebras' innovative approach and persistence transformed it into a leading player in AI hardware, highlighting the high-risk, high-reward nature of cutting-edge tech startups.
