Saturdays, 12–2 pm ET · Sat 14 Nov – Sat 5 Dec · $500 for 4 weeks

Who it's for

For professionals who are done copy-pasting into ChatGPT.

Any role, one task that eats your week

Ops, marketing, sales, finance, HR, project or product management, or something at home. Bring the task; in the first session we cut it to one app you can finish in four weeks.

Already uses ChatGPT or Claude

You ask AI for help every day, but it's still copy-paste. You want an app that does the task for you.

No coding background needed

An AI coding tool, such as Claude Code or Cursor, writes the code. We show you how, step by step, every Saturday.

How it runs

One live Saturday a week. Help every weekday.

Every Saturday, 12–2 pm ET (9–11 am PT): two 45-minute sittings with a 30-minute break. On other days you build, and we work async in a private Slack channel, so it fits around your job.

Every week

Learn it Saturday. Build it all week.

Each week ends with a milestone you demo, so you never fall behind quietly.

  • Saturday, 12–2 pm ET: sitting one is demos and the week's idea, built live. Then a 30-minute break. Sitting two is a build-along to start your milestone.
  • Monday: the week's brief in Slack, with notes and a short drill in the cohort app.
  • Every weekday: a daily check-in thread (done, stuck, next), and answers in Slack within 24 hours.
  • Mid-week: a recorded review of your build, with what to fix next.
  • Recorded: every session, in case you miss one.

Questions

Things people ask first.

How does admission work?

Apply in about ten minutes. We read every application ourselves and reply within 2 hours. Apply by Tue 10 Nov; if you're accepted you get a link to secure your seat, and you pay by Fri 13 Nov, 11:59 pm ET.

When does it start, and is there a later batch?

The first batch starts Sat 14 Nov and runs four weeks. A new batch starts every 4 weeks after that, so if you miss this one, apply for the next.

Do I need to know how to code?

No. You build with an AI coding tool, such as Claude Code or Cursor, that writes the code. We show you how, step by step, and help in Slack every weekday.

What kind of app will I build?

Your own app: one user, one job, one AI workflow. For example, an app that turns 40 support tickets into the Monday summary for your manager, or one that reads receipts into a budget sheet.

What will it cost beyond the seat?

Vendor free tiers cover the build. Budget about $10 of OpenRouter credit.

How much time does it take?

Two hours live on Saturday, plus about 5–6 hours of async building in the week. Every session is recorded, and you can ask in Slack any day.

Will you ask for a testimonial?

We will ask for a short written or video testimonial, and whether we may show your app as a case study. Both are optional. If you came to a live workshop, you pay only the difference when you apply by Tue, Nov 10 and pay by Fri, Nov 13.

Can my employer pay?

Yes. We send an invoice and a receipt on request, so you can claim it from a learning budget.

Who owns what I build?

You do. Everything runs on your own accounts from day one.

What if I miss a session?

Every session is recorded, the notes and drills are in the cohort app, and you can post your milestone demo in Slack.

Is there a session on Thanksgiving weekend?

Yes. Sat Nov 28 (Thanksgiving weekend) runs as usual and is recorded, with an extra live Q&A on Mon Nov 30.

What if I want more help than the cohort?

Fractional CAIO adds your own repo, set up and deployed with you, standups twice a week and priority support, at $1,000 a 2-week sprint. Your cohort fee counts toward your first sprint: pay the difference. See h1902y.com/caio.

What's the refund policy?

A prorated refund for the weeks left, less a $50 admin fee. Email support@h1902y.com.

Is there an age limit?

You must be 18 or older to apply. We ask for your date of birth on the form and keep nothing if you're under 18.
