Actor and Hollywood media mogul Will Smith  surprised the TechCrunch Disrupt SF 2019 audience this afternoon by announcing he would invest $10K in a startup that pitched to him onstage as part of an “elevator pitch” contest, where the winner would get to take a selfie with the star. The company, Socionado.com, helps companies with their social media presence. However, what got Smith’s attention was their well-delivered pitch, he said.
