Proactive agent that thinks and acts like you.
Multiplayer AI Brain for teams.
Proper GUI for commanding 50 agents.

https://t.co/zsDxICHezv is all three. Sauna goes live today. First 2000 people, use access code LAUNCH for $80 of weekly(!) credits.

Let’s explain. Multiplayer only works once the personal brain is powerful. So let's start here.

Personal AI Brain
3,800+ tools connected. State of the Art memory. Skills and schedules you teach once that get repeated forever on cheaper models. An AI first CRM.

Lives on the cloud so you can initiate tasks from anywhere: iMessage, Slack, Email. Also no need for a Mac mini 😉

GUI
AI agents have been stuck in their MS-DOS era. A chat box, a scroll buffer, no way to command 50 of them. We built the first GUI: Live sessions on one side, work waiting for your sign-off on the other, plus the things Sauna kicked off while you were asleep waiting for review. Game mode helps clear the queue with actual joy.

Okay so far so good, but how to give benefit of what you built to more people or whole team?

Multiplayer
Once your Sauna actually knows you and you gave her access to your tools, you can use multiplayer.

Two modes:
- Brain access. My co-founder Robert plugged my brain as a tool into his Sauna last month. He can ask it about pricing while I'm in other meetings, gets a sourced answer back, never has to interrupt me. That’s read only. Yolo mode gives him access to all my tools too :O
- Communal Saunas extend that to whole companies with proper permissioning. Folder owners decide what's true for the whole company and build skills. Most get their personal brain + read access to communal files and memories. Works also for group planning my best friend's bachelor party.

The Way
I’ve been obsessed about AI Brain since 2016. Our human brains suck at some things like memory and are brilliant at others like creativity. We are also particularly bad at thinking we are all on the same page and then realising weeks later that we weren’t. Most leaders spend their days being the human diff tool, catching contradictions in hallway conversations and Slack threads. Repeating themselves 50 times. Now every company is spinning up hundreds or thousands of agents that drift faster than humans do, feeding each other their drift as context. Compounding rot.

After 10 years and one failed company in this space we are launching the solution.

The Launch
We thought about a celebrity launch. Margot Robbie in a bathtub explaining agents. But then we realised the same money gives the first 2,000 people free daily credits, every day, until we burn through that $1,000,000.

Sauna runs Claude, GPT-5, Gemini, GLM-5.1, DeepSeek, Kimi so you can budget yourself. The labs are racing to lock you so they can milk you in a year. We picked your side.

Onboarding
It’s live at https://t.co/8ekc1ZtzoJ We’ve preheated saunas based on a niche. Use the access codes in the comments to get a better experience.

LAUNCH OF https://t.co/8qKyL2Abrm in 12 HOURS. Get excited!!! freemium of the most powerful AI agent is coming, for the first 2000 people we will keep giving you free daily credits until we spend $1mm.

https://t.co/zsDxICHezv is a multiplayer AI brain — an AI workspace that finally knows you, does the proactive work you shouldn't have to do yourself, and leaves you with the parts that need a human: taste, review, and responsibility for what gets sent. For teams it becomes hive mind with permissioning and delegated access.

Building AI automation in GTM & a lesson:

AI works easiest when latency doesn't matter & you don't need to be correct every time.

Outbound emails? Amazing. Real-time support? That's gonna be tricky.

Pick your use case by what's forgiving and has asymmetric upside

Going to be in SF tonight-Monday. Looking for a sofa to crash on for a night. Can bring food and cheeky British tech banter

[Kamil Ruczynski @unable0_]

i’m looking for ringo! 🥁

every great band needs someone with exceptional timing.

the beatles had bold ideas and powerful creative energy, yet what made their music feel effortless was rhythm. ringo brought a rare combination of product sense and technical control. he understood what the song needed in each moment and had the precision to deliver it consistently, shaping the emotional arc in a way that made the entire band sound tighter.

i’m looking for a design engineer with that same combination.

someone whose product sense guides decisions at every level, and whose technical depth allows those decisions to materialize in production. someone who understands pacing, proportion, motion, and detail instinctively, and can translate that instinct into a system that feels coherent and alive.

the difference between good and great products lives in thousands of small decisions. the right design engineer sees those decisions clearly and has the skill to shape them directly, turning architecture, interaction, and performance into instruments of clarity.

if you instinctively know when something is almost right but not quite, and you have the skill to close that gap yourself, i’d love to talk.

@ayoungh Great idea!
