The recent blockbuster IPO of Cerebras Systems delivered substantial returns for major backer Benchmark, which retains a 9.5% stake in the AI chip maker. Benchmark General Partner Eric Vishria, a board member since the company's 2016 founding, co-led the initial $25 million Series A round. However, Vishria almost skipped the introductory meeting, viewing it skeptically as his firm rarely invests in hardware, especially just 18 months into his VC career.

Vishria's initial reluctance dissolved upon seeing the presentation from co-founder and CEO Andrew Feldman. A key turning point was Feldman's assertion that standard GPUs were fundamentally ill-suited for deep learning, convincing Vishria that Cerebras’ approach—building custom, giant-sized AI training chips—was sound. Despite this immediate interest, Benchmark partners required Vishria to secure validation from founding partner Bruce Dunlevie, who possessed necessary hardware expertise.

Dunlevie ultimately approved the investment despite warnings about the inherent difficulty of hardware fabrication and concerns over market adoption. The team, which previously sold SeaMicro to AMD, convinced investors of their execution capability. This conviction carried Cerebras through 8.5 years of intensive development, including inventing novel cooling and manufacturing techniques for its complex wafer-scale engine before its successful public debut.
