One job each
A launch checklist your coding agent runs. A scan for money leaking out of a Stripe account. Receipt-chasing emails for a bookkeeper's month-end. Each one ends with a clear answer.
A small product studio
Zephos builds small products that do one specific job, sell at a plain price and deliver themselves. AI agents do most of the building, checking and shipping. A person decides what's worth making and what goes out under the name.
01
The products we like are the unglamorous kind: a known problem, a person who already has it, and a fix that's easy to explain.

One-time payments on a public page. No calls, no quotes, no trial that turns into a subscription you forgot about.
Pay through Stripe and you land on your download straight away. Support is a DM on X, and a person reads it.

For solo bookkeepers
AI does the typing. You do the judgment.
For solo bookkeepers on QuickBooks Online or Xero: missing-receipt emails clients actually answer, an AI policy you can show them, and Claude and ChatGPT skills for the close.

The studio is set up so a new product is mostly configuration, and so nothing ships without being checked.
Every product is a single entry: name, price, checkout link, how it's delivered. The same template renders every product page from it.
Writing the product, the page and the tests is done by AI agents, with a person reviewing what they produce.
Every deploy runs layout and visual tests on every page at phone and desktop widths, and stops if anything fails.
One internal dashboard tracks sales and visits per product and audits that each page, checkout link and download still works.

If we can't say what it does, how much of it, and what it costs, we're not ready to talk about it.
Every result comes with how it was reached. You shouldn't have to take our word for it, or the AI's.
A self-check is not an audit, and a template is not legal advice. We put the limits on the label.
No countdowns, no "only 3 left". It's software. It doesn't run out.
05
Short, checked answers to questions people search for before launching on Supabase and Stripe, with the commands to verify them yourself. All answers.

Other products are being built. They'll show up here when they work, not before.
