Ashton Kutcher isn't just a tech investor--he also plays one on TV.
Kutcher, who replaced Charlie Sheen on "Two and a Half Men" as Internet billionaire Walden Schmidt, subtly showed off some real-world startups -- several of which the actor has invested in -- in the latest episode of the sitcom.
According to a tweet from Foursquare co-founder and CEO Dennis Crowley, in one scene on the show, Kutcher was shown using a laptop computer covered with stickers from several startups.
The startups that got a shout-out on the show include group text messaging service GroupMe, which was recently acquired by Skype, location-based service Foursquare, online textbook rental company Chegg, Flipboard, an iPad news reader, and Hipmunk, a flight search startup. Two additional stickers made a cameo on Kutcher's laptop, but we can't identify them (Can you? Let us know in the comments below). Check out a photo of Kutcher's startup sticker-studded computer here, which was posted to Instagram by Crowley.
Kutcher is an investor in a number of the companies he plugged on the show, including Flipboard, Foursquare, and Hipmunk.
He came under fire earlier this year over allegations that he did not properly disclose his investments when he guest-edited an issue of Details magazine that prominently featured several startups in which Kutcher has a financial interest. Though the FTC ultimately decided not to probe Kutcher's failure to more openly highlight his stakes in the startups, the New York Times' Nick Bilton noted, "The special issue, called 'The Social Issue,' showcases some fast-growing technology start-ups without making it clear that Mr. Kutcher is an investor in a majority of them, including Foursquare, Flipboard and Airbnb."WATCH:
