Anyone Can Make a Video Game Now. This Startup Is Proving It - Marc Cellucci

Anyone Can Make a Video Game Now. This Startup Is Proving It - Marc Cellucci

In this episode of the Produck Podcast, Lee Jean sits down with Marc Cellucci, founder and CEO of Tempesta, for a 25-year tour through the gaming industry - from producing titles during Sega's Dreamcast era to building an AI platform in Japan where anyone can create a full, playable game world from a single sentence in under two minutes.Marc's career started at Sega in 1999, ran through learning Japanese from scratch and passing the hardest proficiency certification they offer, getting hired at Koei Tecmo, returning to Sega Japan as an arcade producer, and eventually starting an app company the exact week Steve Jobs announced the iPhone - which he later sold. Then he looked around and asked: what can AI do for gaming that has never been done before? That question became Spindle.They cover why Japan's arcades went from cutting-edge gaming machines to crane games and why it makes total business sense, what actually goes into making a AAA title (a lot of spreadsheets and not much that's glamorous), how Spindle generates a full interactive world from a one-line idea, and why Marc thinks most AI gaming is slop and what it takes to do it differently. Marc also walks through his path through the Antler cohort in Japan, funding from Shizen Capital, and the Supercell AI Innovation Lab - which included a trip to Lapland and a reindeer sled.His theory on Japan: let Silicon Valley build the cassette player. Japan builds the Walkman.Connect with Marc Cellucci on LinkedIn: https://www.linkedin.com/in/marc-cellucci/Check out Tempesta / Spindle: [Website URL]#produckpodcast #aigaming #startupjapan #gamedev #entrepreneurship #leejean #tempesta #spindle #gaming #japanstartup #founders #aitools #ugc #gamecreator

Confidence Isn't Born. It's Built From Being Broken - Ayaka (Aya) Murai

When Aya was a teenager, she was bullied for being too tall and not fitting Japanese beauty standards. Instead of collapsing, she drew up a vision of her "ideal self" and reverse-engineered every step to become her. What followed was one of the most relentless reinventions you'll hear this year.In this episode of the Produck Podcast, Lee Jean sits down with Ayaka (Aya) Murai, co-founder and country manager of Idea Boxes Japan, to unpack a journey that includes self-taught English, a beauty pageant stage, a startup betrayal that left her unable to eat for three days, and a worship song on Instagram that changed everything. Aya is still early in her story, but what she has already lived through is worth every minute of your time.What we get into:- How Aya created a detailed "ideal self" vision as a teenager and built a plan to become her- The hostel trick she used to teach herself English with zero scores and zero safety net- Becoming a beauty pageant finalist as someone who was told she never fit the Japanese beauty mold- The startup betrayal that left her broke, alone in Japan, and stuck in bed for three days barely eating- How a worship song on Instagram found her at her lowest and led her to Christianity- Why she attended 100 to 150 startup events in a single year to rebuild her entire world from scratch- Why confidence is something you earn through hardship, not something you are born withAyaka (Aya) Murai is the co-founder and country manager of Idea Boxes Japan. Idea Boxes is a startup studio headquartered in New York, with offices in Armenia and London, that helps founders build companies from 0 to 1 with no upfront cost, providing tech in exchange for future revenue share or equity.

Can AI Ever Replace Human Drivers? Max Frenzel, CTPO of Track Titan Answers

After one session using Track Titan's AI coaching tool, drivers improve their lap time by more than half a second on average. That's 150,000 laps analyzed every single day, more than one million kilometers of racing telemetry, all feeding an AI system built to turn anyone from a Gran Turismo casual into a competitive sim racer.In this episode of the Produck Podcast, Lee sits down with Max Frenzel, CTPO of Track Titan, a physicist-turned-AI-researcher who spent 12 years going from a Tokyo postdoc fellowship to leading AI at Mercari before finding his dream intersection of technology and motorsport. Max breaks down exactly how Track Titan works, where the sport is heading, and why the rest of the world is sleeping on what sim racing can actually do for your driving career.What we cover:- How Track Titan captures 250 telemetry channels per session (brake pressure, tire temps, throttle, steering angle) and translates them into actionable coaching that beginners and pros can both use- Why most beginner drivers brake too late and how that one fix alone saves enormous lap time, explained through Track Titan's trail braking data- The sim-to-real pipeline: why jumping from iRacing to a real racetrack is actually easier than the other way around, and how Max's team includes a GT Academy winner who raced at Le Mans- Why AI will never replace human race drivers (and what the Sony Gran Turismo AI, Sophy, is actually teaching us about the ceiling of human performance)- Max's best-selling book "Time Off" and why your rest ethic is just as important as your work ethic, especially in Japan's work culture- The Future of Speed event: Japan's first motorsport tech event, and why the AI and software side of professional racing teams is surprisingly underfundedMax Frenzel is the CTPO of Track Titan, the leading AI coaching platform for sim and real-world racing drivers. He holds a PhD in physics from Imperial College London and a postdoc from Tokyo University, and has spent over a decade working across AI research, engineering, and product at startups and companies including Toyota and Mercari. He is also the co-author of "Time Off," a best-selling book on the science and philosophy of rest that hit number one on Amazon in multiple categories and has been translated into five languages.Connect with Max Frenzel on LinkedIn: [LinkedIn URL]Check out Track Titan at tracktitan.io and pick up "Time Off" wherever books are sold.Support the Show: If you enjoy the Produck Podcast and want to help keep it going, becoming a Patreon supporter is the best way to do it.

87% of AI Agents Have Already Been Hacked. Is Yours One of Them? - Achraf Jday

87% of AI agents deployed worldwide have already been attacked. 80% of companies say their agents are doing things out of control. And the average cost of a data breach? Nearly $6 million. The problem is here, it's growing fast, and most people have no idea.In this episode of the Produck Podcast, Lee sits down with Achraf "Ash" Jday, co-founder of Antitech, a startup building AI agents that hack other AI agents in order to secure them.

The Middle Word in "Execution" Is "Cut" — Here's What That Means - Marcel Jonté

Most entrepreneurs are stuck in a hamster wheel — running hard but going nowhere. Marcel Jonté has a name for it: RRAs, or Result-Reducing Activities. And the first step to escaping them? Understanding that the middle word in "execution" is "cut." In this episode of the Produck Podcast, Lee sits down with Marcel Jonté — founder and CEO of Japan Kingdom Builders, pastor, and entrepreneur coach — for the show's very first in-person episode, recorded in Tokyo, Japan. Marcel shares how a season of profound grief became the catalyst for everything he's building, and breaks down the exact frameworks he uses to help creators and founders go from clarity to execution. What we get into: - The 4 C's of Japan Kingdom Builders: Creative, Compassion, Community, and Commerce — and how Marcel's team has rehabilitated 13 homeless people off the streets of Shinjuku - RRAs vs. RPAs: why most entrepreneurs are busy doing the wrong things, and how to identify and cut what's not moving the needle - The hidden RRA killing your growth: chasing algorithms instead of outcomes, and building products nobody asked for - Implementation vs. IP: why teaching piano lessons will never scale — and what to do instead- The SES personal brand framework (Story, Experiences, Skills) and why your "boring" story has more value than you think - Why money is energy: Marcel's take on currency, mindset, and what it really means to attract abundance Marcel Jonté is the founder and CEO of Japan Kingdom Builders, a Tokyo-based organization built on four pillars: creative arts education, homeless outreach, church community, and entrepreneurship coaching. He came to Japan at 13 through his father's military career and has been building roots — and impact — ever since.
