Establishing a truly successful enterprise is far from being a side endeavor or a neatly contained forty-hour-a-week occupation. When an entrepreneur sets out to challenge an organization valued in the trillions—an entity that quite literally defines its industry—the mission transforms into something that consumes nearly every waking moment. The notion that greatness or market-shifting innovation could be achieved while preserving the boundaries of a conventional work-life balance seems, to some leaders, inconceivable.

Andrew Feldman, the CEO of Cerebras, articulated this conviction during a recent conversation on Harry Stebbings’ 20VC podcast. For Feldman, the belief that one can produce something extraordinary while adhering to a modest weekly schedule of thirty-eight or forty hours defies both logic and experience. His observation underscores a philosophy deeply entrenched in entrepreneurial reality: transformative outcomes demand unrelenting devotion, not intermittent attention. Cerebras, under Feldman’s leadership, has audaciously set its sights on challenging the technological and commercial supremacy of Nvidia—an industry titan that has come to dominate the global market for artificial intelligence semiconductors. In this David-versus-Goliath contest, Feldman sees himself quite literally as the David—a smaller but fiercely determined innovator confronting a giant whose strength is measured in both scale and capital.

He explained that tackling such a formidable opponent requires a commitment of extraordinary intensity. To attempt disruption with only restrained effort, he argued, would be futile. “One cannot meaningfully go up against the status quo—against an entrenched and immensely powerful competitor—while applying only modest energy,” he said in an interview with Business Insider. Feldman emphasized that excellence, whether in entrepreneurship or any pursuit of mastery, stems from a level of dedication that transcends simple time allocation. True commitment, in his view, does not exist as a fractional portion of one’s schedule; it is an all-encompassing state of being, a perpetual engagement of thought and purpose.

Feldman’s perspective reflects a longstanding cultural ethos prevalent in Silicon Valley—a celebrated but frequently controversial mindset known as hustle culture. It prizes unceasing effort, personal sacrifice, and the belief that radical innovation is born only through relentless labor. Yet, he acknowledged, not all successful leaders subscribe to this philosophy. When asked about Warren Buffett’s famously disciplined work-life balance and his insistence on maintaining time for reflection and rest, Feldman raised a provocative question. Would Buffett and his late partner, Charlie Munger, he wondered, prefer to invest in a company led by founders who live and breathe their mission—who devote every ounce of energy to scaling mountains and dismantling obstacles—or in one where the founders consistently clock out at five or six, detached from their enterprise until the next day? His rhetorical inquiry invited reflection on what level of passion and endurance truly fuels enduring success.

To illustrate the type of devotion he deems necessary, Feldman invoked an analogy drawn from professional sports. He recounted the story of NFL Hall of Famer Steve Young, who once observed his teammate and fellow legend Jerry Rice practicing his routes on the very day their team had celebrated a Super Bowl victory. For Feldman, the story embodies the essence of enduring excellence: even at the pinnacle of achievement, those who are truly great continue to refine their craft, driven not by obligation but by an internal compulsion to be better than they were yesterday. This philosophy, he implied, applies as vividly to entrepreneurship as it does to elite athletics—success is reserved for those who persist when others pause.

In Feldman’s words, great achievements are inseparable from tireless effort. Those who aspire to build something that reshapes markets or defines new industries must possess both the stamina and the passion to sustain the journey. Interestingly, Feldman asserted that finding employees who share this drive is not particularly difficult within his company. Engineers, he explained, rarely enter their profession with the intent to produce only incremental improvements upon what already exists. Instead, engineering attracts individuals who are motivated by curiosity, creativity, and the desire to construct things that have never before existed. To build better and differently—to create systems and tools that genuinely change the world—is an ambition woven into the DNA of innovation itself. Inside Cerebras, he emphasized, the company seeks precisely those individuals: people whose intrinsic motivation aligns with the enormous challenge of building the future.

For Feldman, nurturing such a culture means surrounding himself with relentless builders who measure their satisfaction not in hours worked but in the scale of progress achieved. Extraordinary companies demand extraordinary people—professionals whose motivation derives not merely from compensation or recognition but from the deeper fulfillment of creation itself. In championing this perspective, Feldman reveals not just a belief in hard work, but a vision of greatness sustained by ceaseless curiosity, personal courage, and an unwavering commitment to the craft of building what has never before been built.
