David Nussbaum started Proto Hologram in his living room in 2018 to answer a simple question: what if instead of using holograms to bring back dead musicians, you used them to connect the living? The result is a seven-foot-tall holographic display that lets people beam into rooms across the world—live, prerecorded, or as interactive AI avatars that speak more than 300 languages and dialects.
His background is broadcasting. As a kid, David sat in his dad's Volkswagen listening to talk radio, fascinated by communicating with someone who wasn’t physically there.
That turned into an obsession with connection across distance—first as a radio broadcaster, then as one of the first 1000 podcasters on Apple, where he eventually met his wife. Proto is the next evolution of that obsession: instead of talking into a phone, you broadcast yourself as a hologram.
Episode Highlights:
- Broadcasting obsession started in a Volkswagen listening to talk radio, led to a Howard Stern fixation at 14, turned into 25–30 years in radio and one of the first 1000 podcasts on Apple—where David met his wife.
- William Shatner beams into Sydney for a keynote and calls Proto a time machine because it saved him two weeks of travel—he gave his speech and was home having breakfast with his wife in LA the same morning.
- Christie’s beams multi-million-dollar sculptures and paintings globally instead of physically shipping them, protecting priceless works while giving collectors intimate previews before auction.
- Healthcare is the next frontier: oncologists beam into rural clinics, HIPAA compliance is live, and David’s goal is to replace flat Zoom calls and virtual doctor visits with the presence of holographic physicians for cancer patients receiving sensitive news.
David Nussbaum has spent his life obsessed with connection across distance. Proto is the latest evolution of that mission. His favorite part: he still sells through experience—visitors create their own AI avatar in the office and walk out with a piece of the technology.
Watch the full conversation on YouTube to hear why David believes AI isn’t something to fear, but something to embrace—and how using it well can create connection instead of replacement.
