He Built Siri at Apple. Now His Private AI Runs Inside the FBI, Google, and Netflix.
This week we sat down with Ivan Lee, co-founder and CEO of Datasaur, to dig into why the most regulated companies on earth are running AI on their own servers. Ivan worked on AI products at Yahoo and then on Siri at Apple before founding Datasaur eight years ago. The FBI, Google, Netflix, Zoom, Deloitte, and AmLaw 100 law firms are all clients. Greg Brockman, co-founder of OpenAI, is an investor.We covered the real token economics of enterprise AI, why the open weights model performance gap has almost closed, how Datasaur's proprietary model factory works, and Ivan's personal MCP build connecting Claude to his Whoop bracelet for a daily training plan.We also covered Meta Muse crossing 10 million users in 6 weeks, Anthropic launching Claude Duet, and why everyone is underestimating Google's personal agent.We cover:What Datasaur does — private on-premise AI for the most regulated enterprises on earthWhy companies are switching from public AI after Anthropic launched its own legal and design productsHow the performance gap between proprietary and open weights models has almost closedMeta's 100 billion parameter model running on two Mac Studios — and what that means for private AI costsOne AI agent task uses 3 million tokens vs 2,000 for a ChatGPT queryAI agents crossing the chasm — what happens to token demand when they doDatasaur's model factory — white glove consulting on the outside, productized AI factory on the insideIvan building an MCP server for his Whoop bracelet and giving Claude control of his training planWhy enterprise agents are a better fit than consumer agents right nowMeta Muse crossing 10 million users in 6 weeks with shopping as the top activityAnthropic launching Claude Duet — and why Ivan, who worked on Siri, is watching closelyThe three-way race between OpenAI Dots, Meta Muse, and Anthropic DuetWhy Google's personal agent is being underestimated by everyoneIf you are building with AI, managing enterprise data, or want to understand the real economics of the agent wave, this episode is for you.Find Ivan and Datasaur:Website: datasaur.aiLinkedIn: linkedin.com/in/iyliTwitter: x.com/datasauraiNew episodes every Friday at BuiltThisWeek.comTIMESTAMPS[00:00] Intro[00:42] Meet Ivan — co-founder and CEO of Datasaur[01:00] Yahoo, Apple Siri, and the path to founding Datasaur[01:24] What Datasaur builds — private AI inside your own infrastructure[02:37] Healthcare, legal, finance, and public sector — who uses it[03:01] Why regulated industries are moving faster on AI than any technology in history[03:54] Domain expertise as the moat — Anthropic enters clients' markets[04:53] Open weights models catching up — the performance gap is closing[05:53] Live benchmark — every open model now clears Claude 4.5[07:24] Hardware costs plummeting — 100B parameter model on two Mac Studios[08:57] The benchmark slide — where agents started actually working[10:43] One AI task uses 3 million tokens — the macro token shift[11:39] Crossing the chasm — chatbots vs agents on the adoption curve[13:41] Agents collapsing software spend — the CPU to token shift[14:23] How Datasaur works with clients — the model factory[16:36] News — Meta Muse crosses 10 million users[17:26] Ivan worked on Siri at Apple — personal agents have always been his passion[18:09] The consumer agent gap — why it took so long[19:14] Jordan on Grok Bot and underestimating Google[20:15] Enterprise vs consumer agents — where the market fit is now[21:08] Ivan's favorite AI build — MCP server for his Whoop bracelet[22:14] Where to find Ivan and Datasaur[22:42] Wrap up#AI #PrivateAI #Datasaur #Enterprise #AppleSiri #OpenAI #BuildWithAI #BuiltThisWeek #Anthropic #MetaMuse #ClaudeDuet #AIAgents
