What does a hologram-obsessed entrepreneur do for a second act after setting up a virtual Ronald Reagan in the Reagan Memorial Library, or beaming Jimmy Kimmel all the way from Hollywood to the Country Music Awards in Nashville? If that entrepreneur is David Nussbaum, the founder of PORTL Hologram, the next logical step is to build a machine that can bring the joy of hologram-based communication to the masses. That’s the goal thanks to a new $3 million round that Nussbaum’s company raised from famed venture investor Tim Draper, former Electronic Arts executive Doug Barry and longtime awards-show producer Joe Lewis. Barry is not only backing the company, he’s also coming on board as its first chief operating officer. Much of this interest can be traced back to the hologram performance given posthumously by Tupac Shakur back at Coachella about eight years ago. Nussbaum turned the excitement generated by that event into a business.
