Ashton Kutcher hit up his Dream Bigger studio Friday, looking scruffy (and hot) as ever.

The actor/tech leader/entrepreneur is not only prepping to take the lead one Two and a Half Men, he recently invested in German start-up "Amen."

Not much is known about the mysterious company other than what appears on the corporate website -- a statement that reads: "This is the Best Place for Having an Opinion in the World. Amen."

Kutcher brought pal Guy Oseary into the deal as well -- he just happens to be Madonna's manager. Together, they visited the company's Berlin headquarters and met with the company bosses who are culled together from Nokia and Twitter.

Hmmm ... could Ashton be investing in the first major competitor to Twitter, the company he helped build with his incessant posts and live broadcast race to get a million followers?
