ROCKET ONE

An engine that runs a founder's whole loop.

Rocket One is the AI engine I built to run my own companies. It takes everything in, cuts the noise, does the work, proves it, ships it and learns from it.

Reliable Orchestration and Control for Knowledge, Execution, and Trust.

Jain Yagi, loop hacker

Indie hackers ship alone. Loop hackers build the loop that ships.

For more than two years I built products by hand, one task at a time. A loop hacker builds the machine around the work instead: one loop that every product, pipeline, page and experiment runs through. Rocket One is that loop.

The grey panels below are made-up examples to show the idea. They are not real data.

  • search clicks down 12% since Tuesday
  • a customer email at 02:14
  • disk on the build machine 91% full
  • an idea, typed on a phone in a queue
  • a competitor changed their pricing page
  • last night's data job did not finish
  • a key expires in nine days

It starts by taking everything in.

Ideas from a phone. Numbers from a pipeline. News, finished work, security findings. A founder alone cannot watch all of it, so no person is asked to.

Each thing is written down once.

One small record, with where it came from and when. Nothing is edited afterwards. A correction is a new record that points at the old one, so the history is always whole.

  • idea answers problem: checkout is slow
  • reading belongs to goal: more signups from search
  • news is about a competitor on the watch list
  • finding blocks goal: nightly numbers
  • one note, linked to nothing

Then the dots meet.

An idea is tied to the problem it answers. A number is tied to the goal it serves. A fact standing alone is usually noise. The picture is in the links.

  • version 1.4.2 released to staging
  • 41 runs completed
  • Disk full in two days at this rate.
  • weekly traffic summary attached
  • three approvals already done
  • A paying customer's payment failed twice. Look today.
  • drift notice, no action

Most of it never reaches me.

One question decides: would I do something different because of this? If not, it stays in the record and stays quiet. What reaches my phone fits in a few lines.

  • Goal free 40 GB on the build machine
  • Done means free space above 30%, checked
  • Started 08:41, no one asked
  • Session opened for this, closes after

Work starts without me.

Each piece of work becomes a goal with a clear finish. A short AI session opens for it, does it and closes. Few sessions stay open, because each machine can only run a handful at once.

  • "Done, should be fine now."
  • commit 3fa9c1e
  • tests 42 of 42 passed
  • free space read back: 37%
  • checked by a second session

Done has to be shown.

A reply is not proof. A commit, a passing test or a number read back is. Anything that matters is checked by a different session than the one that built it.

  • Ready to go out
  • 3 posts, 1 release, $1.18 of spend
  • each one named, nothing can be added
  • One tap on my phone

It goes out on one tap.

Publishing, releasing and spending wait for my fingerprint on my phone. Everything free that can be undone just happens. It is not allowed to invent new ways to ask for my time.

Then one question: did it work?

Out in the world is not the same as worked. The numbers are read a day, a week and a month later, and tied back to the exact thing that went out.

  • Lesson short posts with one number travel further
  • Lesson the nightly job needs a second disk
  • Cost 14 minutes of my attention this week
  • Next the loop turns again

Tomorrow's work starts smarter.

What it cost, what it moved and what went wrong become new records. The next piece of similar work begins from them. Then it all comes round again.

Where it stands, November 2026.

Running on my own machines every day: AI sessions on three computers that find each other, hand work over, and ask me on my phone when something needs a person.

The rest of the loop is being built now, piece by piece, by those same sessions. It is not for sale and there is no waiting list.

If you are a founder building alone and this is the machine you have been trying to build too, write to me.
