The Two and a Half men actor, 37, and investment partner Guy Oseary, 42, launched Sound Ventures at the South by Southwest festival in Austin, Texas, on Sunday.
“We believe that great brands aren’t afraid to disrupt,” Kutcher said at DeLeén Tequila’s Sound Ventures launch party.
While Cuban, 56, took selfies with other guests, the new parents snuck away to joke around and take kissing pictures in the Airbnb photo booth.
Kutcher and Kunis also chatted with Alba, 33, backstage as Lil Wayne performed a 45-minute set of classics like “Lolli Pop,” “She Will” and “A Milli,” which attendee Rashida Jones particularly enjoyed.
DJ Mary Mac performed as well, with Shane West and James Marsden in the audience.
Guests sipped on DeLeén cocktails throughout the evening and indulged in a build-your-own ice cream sandwich bar.
This isn’t Kutcher’s first foray into the tech world: He was an early proponent of Twitter, played Apple founder Steve Jobs in a biopic two years ago and has already invested in Spotify, Airbnb, Foursquare and Uber with Oseary.
