Jack Dorsey, CEO of Square and Twitter.

Square officially filed documents to become a publicly listed company Wednesday. 

It's been a busy couple of weeks for Square's CEO and founder, Jack Dorsey.

On October 5, Twitter announced that Dorsey would be staying on as the company's permanent CEO. He had been named interim CEO of Twitter after Dick Costolo stepped down from his post in July.

It remains to be seen how Dorsey will juggle being the CEO of two public companies at the same time.

Any would-be public company has to list its "risk factors" in its filing document. Intriguingly, but not unexpectedly, Dorsey's double duty as Twitter CEO is listed as a risk factor on Square's SEC documents. 

Still, Dorsey certainly leads an interesting lifestyle - he first become a billionaire in 2012 and is now worth an estimated $2.3 billion.
