"Two guys in a garage in Cupertino, California, create the most valuable company ever. What a great day," Kawasaki told CNBC's "Power Lunch." "Everybody has a hero."
Those two guys in the garage were Jobs and fellow Apple co-founder Steve Wozniak.
Kawasaki has been successful in technology and entrepreneurship for decades, but he got his big start as Apple's chief evangelist in the mid-1980s and then again in the mid-1990s.
Now chief evangelist at graphic design firm Canva, Kawasaki said he never thought Apple would ever be this successful.
"I left Apple twice. Steve Jobs offered me a third job and I turned him down," he said. "Obviously, I never anticipated this day, because I would have stayed,"
He also gave credit where credit was due: "To Steve for his vision and Tim Cook for his execution."
Cook took over as CEO in 2011 after Jobs died of cancer.
And to those doubters, who fear for the company due its reliance on iPhone sales, Kawasaki said he has a message: "Why does it matter? The market has spoken."
Apple hit a market capitalization of $1 trillion on Thursday, becoming the first publicly traded U.S. company to reach the historic valuation.
