What happens when you can transform yourself into any character, in any world, in real time, while streaming live? Dean Leitersdorf is the CEO and co-founder of Decart, an Israeli AI company that just cracked the code on real-time generative video. Within a week of launching at TwitchCon, Twitch streamers were making thousands of dollars per hour letting their audiences morph them into cartoon characters, fantasy worlds, and entirely new realities—live, on stream, for three dollars per hour of AI processing.Dean's insight: the next wave of AI doesn't just make video generation faster or cheaper. It makes it interactive. Creators can now edit themselves, their backgrounds, and entire environments on the fly during Zoom calls, live streams, or gaming sessions. Decart runs this at roughly 100x cheaper than competitors and is targeting another 100x cost reduction over the next year to reach YouTube-level pricing (cents per hour instead of dollars). That shift unlocks new markets—gaming mods, consumer filters, XR glasses, and eventually robotics training in photorealistic simulated worlds.News: Humans&, a 3-month-old AI lab founded by researchers from Anthropic, Google, and X AI, raises $480 million at a $4 billion valuation based almost entirely on founder pedigree. Xreal sues Viture for patent infringement in bird bath optics, echoing the very lawsuit Magic Leap filed against Xreal years ago—a cycle of irony layered with allegations of trade secret theft and China-based IP evasion. OpenAI discloses $20 billion in revenue but rumored $50–60 billion in annual operating expenses, raising questions about path to profitability. TikTok's US operations close under Oracle's stewardship, and a new vertical drama app called Pinedrama launches. ElevenLabs launches music generation, competing with Suno and Udio.Key Moments Timestamps:[00:20:30] Dean's background: Israeli tech ecosystem, the Technion, and building a team of 0.001 percenters[00:22:00] The real-time video demo: transforming Dean into a cartoon character, live, during the podcast[00:26:30] Decart's competitive advantage: 100x cheaper than competitors, targeting another 100x reduction[00:28:00] TwitchCon success: streamers making $2,000/hour letting audiences control real-time transformations[00:31:00] Exit strategy or go-it-alone: why Decart believes foundational model owners capture the market[00:40:00] XR and robotics use cases: world reshaping, robot training simulations, AR glasses at 6K/120fps[00:48:30] Culture and talent: renting 34 apartments next to the office so engineers live two minutes away[00:55:00] The secret sauce: synthetic data from game engines beats internet-scale scrapingDean explains why Snap Camera's 10-year-old integration into stadium kiss cams proves the market is ready for the next evolution, how world models will power the next generation of XR glasses, and why the bottleneck shifts from rendering to semantics—making sure a virtual car doesn't block a real-world foot.
