They're two titans of global investment.

The same species, you might say:

(SOUNDBITE) (English) SOFTBANK'S FOUNDER AND CEO, MASAYOSHI SON, SAYING:

"We were same animal. We were both a little crazy."

Softbank chief Masayoshi Son sat down with Alibaba founder Jack Ma in Tokyo on Friday.

The two go way back.

Son owns 26% of Alibaba.

His original investment of 20 million dollars in 2000 is now worth about 100 billion.

But the pair met just weeks after Son was forced to bail out WeWork with almost ten billion dollars in emergency funds.

That has caused some to ask if the legendary investor has lost his touch.

Ma is still a fan:

(SOUNDBITE) (English) ALIBABA'S CO-FOUNDER, JACK MA, SAYING:

"He probably has the biggest guts in the world, on doing investment. Very few people in the world have that courage."

SON RESPONDING: (OFF-SCREEN) "Too much guts, sometimes I lose a lot of money."

"I know."

Son himself is unabashed.

He's promised to keep going with his gut on big investment decisions.

(SOUNDBITE) (English) SOFTBANK'S FOUNDER AND CEO, MASAYOSHI SON, SAYING:

"In the next ten years, I will continue to invest more and more. Because the world needs a continuous revolution."

Son is pushing ahead with his next big investment project - Vision Fund 2, which he has promised will raise up to 108 billion dollars.

Ma though is exiting the stage.

The 55-year old stepped down as Alibaba chairman in September to focus on philanthropic projects.
