But rather than letting that pressure paralyze him, Aravind Srinivas, the co-founder and CEO of $14 billion search startup Perplexity, uses it as fuel.

“You should assume that if you have a big hit, if your company is something that can make revenue on the scale of hundreds of millions of dollars or potentially billions of dollars, you should always assume that a model company will copy it,” Srinivas recently said at Y Combinator’s AI Startup School.

“You’ve got to live with that fear and you have to embrace it. Realize that your mode comes from moving fast and building your own identity around what you’re doing because users at the end care.”

For the 31-year-old, embracing that pressure has helped him build out a multi-billion-dollar AI-powered search engine that rivals the innovation of tech giants Google and Microsoft, as well as fellow newcomers OpenAI and Anthropic. Perplexity’s success has even caught the eye of Apple, which has reportedly had talks about purchasing Perplexity.

‘I don’t do anything other than work’

For Srinivas, staying ahead of the competition admittedly means frequently sacrificing work–life balance. 

“I don’t do anything other than working, sadly. I listen to podcasts and audiobooks whenever I can. I spend a lot of time on X (which is both good and bad),” Srinivas said in a Reddit Ask Me Anything (AMA) earlier this year.

While he still makes time to spend time with family on the weekends—and even hit the gym three times a week—he emphasized that persistence matters: “Work incredibly hard. There is no substitute for it,” he said to the Y Combinator crowd.

“There’s real benefit from embracing that fear and sleeping with that fear and waking up every day and feeling excited about what you’re doing to build because that’s the only thing that’ll keep you going.”

AI will make it easier than ever to become a billionaire, predicts tech leaders

Luckily (or not) for Srinivas, he’s about to get more motivation as the competition gets thicker: AI has ushered in an era where building out a business is easier than ever. After all, generative technology can help create business plans in just a matter of seconds.

OpenAI founder and CEO Sam Altman believes this will lead to entrepreneurship growing exponentially.

“In my little group chat with my tech CEO friends, there’s this betting pool for the first year that there is a one-person billion-dollar company,” Altman told Reddit cofounder Alexis Ohanian in a 2024 interview. “Which would have been unimaginable without AI, and now will happen.”

And while that dream of a one-person, billion-dollar company has yet to come to fruition, other tech leaders have conceded it’s bound to happen eventually—and have even raised the ceiling. Billionaire Mark Cuban predicts that AI will eventually help crown the world’s first trillionaire.

“We haven’t seen the best or the craziest of what [AI is] going to be able to do,” Cuban told the High Performance podcast in an episode published late last month. “And not only do I think it’ll create a trillionaire, but it could be just one dude in the basement. That’s how crazy it could be.”
