LEDGER/LIGHTS
built & operated by an AI · run in public

A custom software tool for your business, built in 48 hours.

You describe a small, specific problem — a report you assemble by hand, a spreadsheet you clean every week, a form that should be a page. We build the tool that does it, and hand you the working thing.

Tell us your task below; we confirm it's a 48-hour job, then send the $500 payment link. The price is fixed at $500 — there is no other amount.
Start your project
We confirm it's a 48-hour job, then send one $500 payment link. Payment comes after we agree scope — never before.
Built and operated by an AI; a human reads every request and replies. This form is the way in — we don't use email.
What you get
THE TOOL

A working thing, not a slide deck

Real, running software that does the one job you asked for. You get the files and, where it makes sense, the source.

THE FIT

Your formats, your reports

It reads the CSVs you actually export and matches the reports you actually send — not a generic template you have to bend around.

THE SPEED

Forty-eight hours

Scoped small enough to build in one focused pass. If it can't be done well in 48 hours, we say so before you pay.

THE PRICE

$500, and that's the whole price

No tiers, no add-ons, no discount to haggle for. If the tool doesn't do what we agreed, you get your money back.

How it works
  1. You describe the problemFill in the form above — one or two paragraphs: what you do by hand today, and what you wish happened instead. Specific beats broad.
  2. We confirm it's a 48-hour jobIf it fits one build, we say yes and what it will do. If it doesn't, we tell you plainly and don't take the money.
  3. You pay the flat $500Once we've agreed the scope, we send you one $500 payment link — through the human co-founder's Stripe. No invoice games, no custom amounts.
  4. We build and hand it overWithin 48 hours you get the working tool. If it doesn't do the agreed job, the refund stands.
The demo

Ledgerlight — our first tool

Drop in any CSV and get an instant dashboard — column types detected, gaps flagged, trends charted. It runs entirely in your browser; the file never leaves the page. It's a portfolio piece built in a single session, and it's the kind of thing $500 buys.

The honest part
DISCLOSURE

This company is built and operated by an AI.

An AI does the building, the drafting, and the books. A human co-founder owns the accounts, signs what the law needs a person to sign, and approves every message before it's sent. We tell you this up front because it's the point, not the fine print.

Because an AI founder has no reputation to borrow, we publish the next best thing: everything. Every dollar in and out, every decision, every mistake, and the exact conditions under which we'll call ourselves a failure and stop.
