A wishlist app answers a real question: what do I want? You add the espresso pot, the watch, the trip; the app holds the list, maybe checks prices, maybe lets family peek before a birthday. It is private, it is free, and nothing on it is a promise. For a birthday list or a someday-maybe file, that is exactly the right tool, and no part of this page argues with it.
The question it is not built for is the one a founder asks differently: what does this company buy when a number lands? A want with a number attached behaves unlike a want on a list. It needs a price, a date, and witnesses — and those three things are precisely what a private list cannot hold.
What a wishlist does well
It is open-ended: fifty items, no order, no deadline, no cost. It is private: you can want a café racer without telling a soul, and no one will ever check whether the year you named was the year it happened. And it carries wants that have nothing to do with work — birthdays, holidays, gifts for other people. A ladder cannot do any of that. It is public, it is structured, and it costs money ($9 a month).
What a ladder does differently
A public revenue ladder takes one want at a time and pins it to a rung: the Stovetop espresso pot at the first sale, the Studio Display 5K at $100k ARR. The number is real, the price is real, and the page is open, so the promise has witnesses. When the rung is hit, it gets stamped with a date, and the stamp stays. A wishlist entry drifts; a stamped rung does not. That is the whole difference: the ladder is not a better list, it is a commitment device with an audience.
Where the ladder loses, honestly
If you do not want your wants in public, a ladder is the wrong shape — publicity is its mechanism, not a setting. If your goal has no number attached (a holiday, a taste you are still figuring out), there is no rung to pin it to. If nobody would ever look, you lose the one thing the ladder adds over a private note: with no witnesses, it is a prettier list. And unlike a wishlist app, it is not free — the fee is the rent on the record. For a personal someday-list, that rent buys nothing. Keep the wishlist app for that.
Which one, for what
Gifts for other people, and wants you are not ready to say out loud: the wishlist, every time. One work reward you can name, tied to a number you are already chasing, where saying it in public would make you more likely to do it: that is the rung. The two tools overlap less than they look — a list holds many wants loosely; a ladder holds few wants firmly. The failure mode is not picking the wrong one, it is using a list to dodge the commitment of picking one rung.
The live sample — six rungs from $100k to $100M, two already stamped — shows what “few, firm and public” looks like when it has been running for a while. If that is the shape your work-reward wants, you can draft a ladder in a few minutes; the library of objects, each with its real price and its why, is where the rungs come from.
