🎤 Starting #QConAI New York with a keynote on: “The Next Generation of AI Products” by @hmason, Co-Founder & CEO @playhiddendoor.
As teams race to put AI into production, the keynote zooms in on the foundations that actually make systems hold up under real usage. #AIEngineering

A new and terrifying world is now available on Hidden Door - Dracula!
Step into Bram Stoker’s world of gothic horror, set in modern-day Amsterdam. Play a vampire, hunter, or an unsuspecting guest - you can even earn the ability to bring vampires into your other worlds!

❓ Is Data Science Dead in the Age of AI ❓
In our latest High Signal episode, @hmason shares why the answer is a resounding “No!”—but the field is undergoing profound changes. Automation is transforming workflows, generative AI is reshaping how problems are solved, and the community is moving beyond its “shiny” phase into something more mature.
💡 Fun fact: Hilary was my guest on the first podcast I ever released, nearly a decade ago. It’s amazing to see how much has changed—and how much has stayed the same.
Key themes we covered:
✨ From Hype to Maturity
Automation is redefining entry-level roles and workflows. What does this mean for the future of data science?
📜 Why Generative AI Needs Context, Not Prompts
“Prompting feels like spellcasting, not engineering,” Hilary says. She explains how context-rich systems—like structured data and multimodal inputs—are the key to unlocking AI’s potential.
⏳ A Decade of Interfaces, Not Algorithms
Even if machine learning progress stopped today, it would take years to design the workflows, tools, and interfaces needed to fully harness its power.
🎧 This episode, produced by @delphina_ai with @dsgilchrist, dives deep into the evolving landscape of data science and what it takes to thrive in an AI-driven world.

Absolutely 🤩 convo with @hmason on the latest CRAFTED.! We dove deep into AI, creativity, and building with soul. An unexpectedly deep conversation.
Also: using GenAI to build immersive worlds for movie and book fans at @PlayHiddenDoor
🎧 Listen: crafted.fm
This is a cool experience, and follows one of my favorite AI design patterns -- let players direct, but not control, the system within the game, so it feels like improv.
What kind of NPC did _you_ love?
New feature: you can now 🪄inspire🪄 key characters in your stories!
Starting with The Crow, when you first encounter your love interest, you’ll get to personalize them! This won’t be like writing their character sheet, though; it’s more like improv.

CEO Hilary and Game Director Chris are in this excellent piece from MIT Tech Review exploring the role of AI in story games. Since founding Hidden Door, we've believed this tech opens up new ways for players to explore the worlds they love, going beyond endless chats with NPCs.
This is tonight! We're way over capacity, but if you know me and want to stop by, reach out.
It’s a beautiful day for a Brooklyn twist on New York Tech Week. Get your hands on creative, interesting products built with AI, enjoy some Brooklyn snacks, and meet some of our favorite Brooklyn founders. Tonight at 6! #nytechweek #techweek #brooklyn
