AI moves faster than you can read about it.
You're not behind because you're slow. You're behind because you're alone.
- The tool everyone recommended in January is third-best now.
- The blog post you found is six months old. In this space that's a decade.
- Nobody at your company is doing this yet, so there's no one to ask.
- By the time a technique makes it into a newsletter, the edge is gone.
The people who stay ahead aren't smarter than you. They're in a room with fifty others testing this stuff in parallel. Someone here already tried it last week. They'll tell you whether it's worth your Tuesday.
What's inside
Access to a room, not a curriculum.
No homework. No mandatory calls. Take what's useful.
01
The frontline feed
What members are testing right now, before it shows up in anyone's newsletter.
02
The agent library
Working agents from members' real businesses. Copy them, adapt them, run them.
03
#what-broke
Post the thing that's failing. People who hit it last month answer.
04
Show-and-tell
Members demo what they built and what it actually cost them. No slides, no pitches.
05
NYC dinners and live sessions
The room, in person.
06
Direct line to Mark
Ask the thing you'd otherwise pay a consultant to answer.
Why people are here
Three jobs. No homework.
Nobody is assigning you modules. You show up for the work you already have.
Improve the business you already run
Pricing, ops, marketing, the analysis you used to pay someone else for.
Automate the work you hate
The recurring stuff that eats your week and never shows up in revenue.
Launch something new
The idea you'd have built years ago if you'd had a team.
This week
What people are talking about.
A sample of what's in the feed right now.
- Anyone else getting worse output since the model update?
- My inbox agent has run unattended for 40 days — here's the whole setup
- Cowork vs. Code for document work: I tested both on the same contract
- Killed $400/mo of tools this quarter. Here's what replaced them.
- Client wants an AI policy doc. Has anyone written one that isn't garbage?
- The thing nobody tells you about running agents on real customer data
Admission
Is this for you?
This is for you if
- You run a company, or a function inside one
- You use AI daily, not occasionally
- You'll share what broke, not just what worked
- You'd rather hear from someone who tried it than read a roundup
This is not for you if
- You want a magic button
- You want to lurk
- You want a course with modules and a certificate — that's The AI Agents Course, and it includes this
- You've never used ChatGPT

Your host
Mark Fershteyn
Non-technical founder. Zero coding background. Built 10+ products with AI.
7 years building products. 13 years closing deals (top 1% seller). 18 months going all-in on AI. Raised $8M from top VCs including CRV, Zoom Ventures, GTMfund, and Stage 2 Capital.
I built this because the useful stuff never makes it into blog posts. It lives in DMs, group chats, and calls with people actually running this in production. This is that, in one room — and I'm in it every day, posting what worked and what wasted my week.
What I've built with AI
- SiteGuides.io — AI-powered website visitor intelligence
- Marketing agents — Reddit, LinkedIn, email outreach on autopilot
- 3 iOS apps — earning hundreds/month with passive growth
- 2 mobile games — built and shipped to the App Store
- Internal tools — automations that replaced an entire marketing team
