Cerebras CEO Andrew Feldman recounts years of doubt before frontier labs signed on

Cerebras CEO Andrew Feldman says the startup was called impossible, then unmanufacturable, then lacked customers, frontier labs and hyperscalers.

In an account posted on X by Rohan Paul, Feldman says Cerebras spent about $8M a month for 18 months on a chip it could not yet make work, reporting to worried investors every six weeks. The report is Feldman's own account and does not include independent confirmation of these figures.
