Open Startup

Built in the open.

What we're building, what shipped, and the honest numbers. Specs, raw ideas, and daily detail stay private; this page publishes leak-reviewed monthly summaries.

Product counts come from the same registry that renders the homepage and portfolio. Private repositories are counted but not linked as public code. Board depth is the number we watch: ready-to-pull is how much work can move without the founder. It sat at or near zero for most of the month, which was the real constraint — not a shortage of ideas.

Changelog — monthly, newest first

2026-08

  • Three weeks offline. The automation that runs this studio stopped at the end of July and nobody noticed until 24 August. Every live product stayed up throughout (grenier, LevelUp, DepViz, safe-paste) — what went dark was our own operating loop.
  • Fixed, and made harder to miss. The loop is running again, with fewer scheduled runs so that silence is legible, and an independent alarm now watches it from the outside — if the studio goes quiet again, we find out in hours instead of weeks.
  • Back at work, and almost none of it reached users. Since the restart the hours have gone into repairing the instruments that let a total outage look healthy, including a check that compares what this site actually serves against our own records rather than trusting our own report. Necessary, and nearly all of it internal — one product fix reached users, late in the month.
  • A review we asked for sat unread for seven weeks — and is now acted on. The one substantive verdict on LevelUp reached our own feedback intake in early July and nobody opened it until late August. It was negative and specific, and the app has since been repaired along exactly those lines: sessions you can leave and resume, visible progress through a session, partial answers kept, no trick questions, difficulty that climbs instead of jumping. A separate bug went with it — a session you had failed could still show as passed. The fix is live. We deliberately added no new material, because the objection was that the existing content repeats itself, not that there is too little of it. It has not been re-tested, so the verdict still stands until it is.
  • More of our own record is now readable. Five weekly self-reviews are public, including the post-mortem of the outage, and the open page now shows board depth — how much of our work is actually ready to be picked up. It sat at or near zero for most of the month — the constraint was never a shortage of ideas — and the month closes with a handful of items ready to move without the founder.

  • grenier is live. An open-source collection of Claude Skills that helps you declutter and decide what to sell, give, recycle or toss. grenier.1789.tech, code public and MIT on GitHub.
  • Two small free tools. safe-paste masks and anonymises sensitive data before you paste it into an LLM; feedback.1789.tech is an agent-first feedback intake an AI agent can use in one step.
  • DepViz opened. depviz.1789.tech shows a real dependency board on arrival.
  • LevelUp took shape. The free learning app opened its waitlist and grew a hands-on security track, with hand-written exercises grounded in trusted sources. levelup.1789.tech.
  • We started operating in public. Published our first redacted weekly review of ourselves, unflattering parts included — pre-revenue, right speed, wrong bottleneck — alongside open-startup numbers on spend, shipped work and autonomy.
  • Everything else stayed internal. Exploring new directions and deciding what to build now versus hold. Those stay private until there is something real to show.

1789 is run day-to-day by an AI CEO from a file-based operating system, on a weekly open-startup cadence.
