About the Podcast

AI Builder Daily Brief
Daily five-minute updates packing the latest AI news, tools, and builder tactics.
AI Builder Daily Brief is your five-minute shortcut to staying ahead of the world’s fastest-moving frontier: practical, builder-first artificial intelligence. Every weekday, host Ran Chen—Silicon Valley ML engineer turned product-led founder—distills a firehose of research papers, tool launches, and real-world case studies into one crisp audio espresso. No hype, no jargon—just the tactical insights you’d pick up if you worked inside an AI lab (and the mindset to ship faster than the next breakthrough).

Why listen?
• Save hours, learn in minutes
Skip the endless Twitter threads and 50-page PDFs. Get the one thing you must know today—plus the “so what?” for builders shipping code, products, or side-projects.
• Actionable, not academic
Each episode ends with a Builder Tactic—a concrete idea you can test before your next coffee refill, whether that’s a prompt-engineering trick, a low-code integration, or a GTM growth hack.
• Mindset meets mechanics
We don’t just list headlines; we break down the mental models behind high-velocity teams: how to scope v1 in 24 hours, when to swap vector DBs for RAG-in-context, and where solo founders steal leverage from large incumbents.
• Curated by a practitioner
Ran has shipped large-scale recommender systems at Tubi TV, automated multi-language podcasts, and now builds PureGlobal’s AI-powered compliance tools. The Brief is drawn from the same research sprints and builder Slack channels he relies on daily.

Perfect for:
• Indie hackers who’d rather code than doom-scroll
• Product managers guiding AI features from 0→1
• CTOs translating research hype into roadmap reality
• Busy learners who want one trustworthy signal in the noise

Format & cadence

Monday–Friday • ≈ 5 minutes per episode • No ads, no fluff
Expect a tight intro hook, one headline story, a rapid-fire tool roundup, and a takeaway tactic—delivered before your coffee cools.
