The team you can't afford
to hire, already on payroll.
Koala Brothers is an AI studio building the Personal Agent OS — a runtime, a shared memory, a set of hands, a crew of specialist agents, and a daily brief — for solo founders running a company with the output of fifty.
Three things to know before
your first call.
The org chart becomes a runtime.
A founder who once needed a marketer, a researcher, a finance lead, and a pair of hands now needs accessto all of them — for an hour, for a Tuesday, for the duration of one decision. AI didn't just make labour cheaper. It made the shape of a company optional.
The team becomes a stack. The hire becomes a config. The morning stand-up becomes a brief.
Running solo is deceptively brutal.
The one-person company sounds like freedom. In practice it's six jobs welded to a single calendar. Every tool you bolt on adds surface area. Every decision lands on the same desk.
The generalist trap.
Marketer at 9. Engineer at 11. Operator at 2. CFO before bed. Five mediocre roles instead of one excellent one.
Your stack doesn't talk.
The average solo founder rents 18 SaaS products. None of them know about the other 17. Every reconciliation lives in your head.
Context-switch tax.
Every 11 minutes your brain reloads — Slack to spreadsheet to docs to Stripe. By Friday, the week is fog and the work is a third done.
Decision fatigue.
Two hundred micro-decisions before lunch. The 201st is where the mistakes live, and there's no one to catch them.
Weekly amnesia.
Last Tuesday's research is dead by Monday morning. You re-discover instead of compounding. Your second brain is a Slack thread you can't find.
Hire-or-scale paradox.
Too small to bring help on. Too busy to compound the work alone. You stall — not because the market said no, but because Tuesday said no.
The answer isn't another chat window or a 19th SaaS subscription. It's an operating system for a personal organisation — one that remembers, acts, and briefs you back.
One organism.
Five surfaces.
At the centre is a Runtime that hosts your agents and a Memory they all share. Around it: a Crew that does the work, Channels that act in the world, and a Brief that brings the result to you. One product. Five iOS modules. Same brain.
One OS.
Shipping as five iOS apps.
Each module ships as a standalone app on iOS or macOS. Together they share one runtime, one memory, and one identity — the backbone that makes them feel like a single organism, not five loose tools.
Lead
/ DiscoveryAI-powered PR & partnership discovery.
Find the journalists and operators who already cover your space, then auto-personalize the reach.
Brief
/ the surfaceYour daily AI briefing, before coffee.
Five-minute synthesis from the inbox, the docs, and the news. Phone-first.
Three things to know before
your first call.
Channels
/ the handsAction layer for your AI org.
Gmail, Calendar, Slack, GitHub, Stripe, Telegram — agents draft and dispatch, you approve.
Crew
/ the teamSpecialist agents you actually hire.
Marketer, Researcher, Operator, CFO — each with a personality, SOPs, a track record.
Runtime
/ the hostWhere your AI organisation lives.
Always on. Speaks plain language. Quiet by default; opinionated when it matters.
Sequence, not slogans.
Public quarterly checkpoints. Things slip; we publish when they do. Apple Developer enrollment is the gate the rest hinges on.
Joey Luo.
Joey is the founder of Koala Brothers and the founder of BlockTempo, a leading tech and finance media in Asia serving millions of monthly readers.
He spent the last decade scaling editorial operations and is now scaling a different kind of organisation — one that runs on agents instead of headcount. In parallel he runs Crab Labs, a research practice exploring the multi-agent architecture, channels, memory, and skills Koala Brothers will eventually productise.
Watch the work
in motion.
We send a letter when something ships, when something fails interestingly, and when we change our minds about how an agent should work. Three or four a quarter.
