If Kevin O’Leary, 71, had to do it all over again at 25, he said he’d focus on two key areas in the tech industry to make it big.

The Shark Tank star and chairman of O’Leary Ventures said in a video this week that if he were a 20-something again, he would focus on the business that is most booming right now: artificial intelligence.

“I think AI growth is going to be exponential,” he said.

But in the vast industry of AI, O’Leary said he would focus on either helping small businesses implement AI tools or developing data centers.

Rather than go straight for the corporate giants, O’Leary said he would first try to narrow his focus to helping businesses with fewer than 500 employees implement AI. These 36 million small businesses make up just under half of the U.S. GDP, according to the Small Business Administration—and while they likely want to use AI, they may not be as quick to adapt as large corporations.
