Litmus Lab
Manually verified · 27 JulNine years of solo work. Slow, unglamorous software for people who need it to be right.
Run byLena LoureiroNo updates yet. The first one lands at the end of this week.
Where backers and the founder talk.
Questions before the weekly call, arguments about which idea should run next, and the founder thinking out loud between updates. Open to anyone backing Litmus Lab, and closed to everyone else — including us, except where a decision it produced is published.
It opens with accounts. Until then there is nothing to sign in to and nothing to read, which is why there is no empty box here pretending otherwise.
You cannot write one here yet. Suggesting an experiment is what the upper tiers are for, and the form for it is not built — during the pilot, ideas reach a founder through whatever channel you already have with them. If you are paying for a tier that promises this, it is not working yet, and that is our fault rather than yours.
Nobody has suggested an idea yet. Backers write them up and the founder picks one.
No experiment has finished yet. The first result publishes at the end of the month — whichever way it lands.
You are not backing them yet, so you are seeing the public version of this page.
- Read every idea people have suggested, in full, including how each one would be measured.
- Whatever the founder chooses to show beyond the public ranges.
- Named on the results you paid for, if you want to be. Credit, not a claim on anything.not built yet
Marked promises are not built yet. The pilot has no accounts, no ballot, no calendar and no second payment path, so anything needing one of those cannot be delivered however much you pay — if a founder honours it, that is them doing it by hand. We have left these on the tiers rather than quietly removing them, because deleting a promise would hide the gap from anyone who had already paid for it.

Joining the waitlist gets you an email. It is not an option, a promise, or a queue position.
Loyalty earns recognition and access only — a badge on your name, earlier access to call seats. Cancelling resets the streak; it never affects money already spent.

- Share of money from the biggest customerLocked
Named, not hidden. A page that concealed the existence of these would be presenting itself as the whole story; a page that showed them would make the tier meaningless.
Thesis never holds your money — the founder's own payment provider collects all of it, and we check how the experiment share is spent. The 15% platform line is what running this site would cost. There is no way to collect it during the pilot, so today that share stays with the founder too.
