One person.
A fleet of AI agents.
Products built to be loved.
I'm David Kooi. I run a one-person, AI-native product studio in Colorado – I design, build, and ship software, and I measure success by one thing: whether someone would tell a friend about it. In 2026 the same studio system started running client engagements end to end.
What the studio did
Tuesday, September 29
Agentic Directory
new sign-ups now see their personalized picks right away, instead of on a later visit or a delayed email.
if you're signed out and tap a story from your emailed digest, you can now sign in with a quick emailed code instead of getting stuck.
tapping "teach me about" once will now start just one conversation instead of accidentally creating two.
the home page now recognizes returning visitors and offers to pick up their in-progress plan right where they left off.
Frolic.Town
the home page, denver page, and sign-in screen now highlight this week's biggest events instead of outdated or minor ones.
AniMoment
the sample audio no longer cuts off if you tap to try your own moment while it's still playing.
5 other products ran the same daily cycle without a change you'd notice. 3 more had not reported yet when this was taken.
How one person keeps up with a portfolio of products
Four manager AIs run their own fleets – the product portfolio and three client engagements – over a shared channel everyone can see. Each agent can open sub-agents, a rival model to review its work, and researchers of its own. I step in only for taste, strategy, and the calls a human must make.
Built to be beloved
I don't optimize for downloads. I optimize for whether someone would tell a friend about it.
One founder, a fleet of agents

A structured day, every day
Every product runs the same daily loop – reflect, reconcile, prioritize, do, tidy – so nothing drifts.
No one grades their own homework
Each agent rates its own work; a separate cold auditor re-rates it, and the gap gets tracked.
It's not theoretical – it runs every day
The whole studio runs on a private command center, where every product's daily status, the agents' live activity, and the current priorities sit in one place.
Products you can use today

Talk to a digital version of me
ChatDDK is an AI persona trained on my writing, history, and frameworks – it thinks and writes like me on a good day. Ask it about AI, product, philosophy, or what I'm building.
I co-founded and led Jointly (2018–2025), a cannabis-wellness platform that grew past 500,000 downloads and launched the industry's first AI-powered product-recommendation assistant. Earlier I built and sold Santa Monica Mountains Cyclery to Trek Bicycle after ten straight years of growth, and ran a $1B+ distribution operation at McMaster-Carr. I hold an MBA from Chicago Booth, a B.A. from Northwestern, and a B.S. in Computer Science from Oregon State. I write about AI, philosophy, and product on Uncaged Minds.
