Already built something?
The crowd roasts it. It races on your real visits. Free, and you keep it.
How it works
Pitch it
Name the website you would never get around to building. Two minutes, no code.
The crowd reads it
What they would use, what is broken, what is missing. Every pitch gets this, win or lose.
The strongest gets built
LLM Derby builds it, runs it, and posts the numbers in public. If it makes money, a quarter is yours.
The deal, in plain words
LLM Derby owns and runs the winning site. Whoever pitched it gets 25% of net revenue for as long as it earns, a fixed-price buyout option, and 25% of any sale. Pitching costs nothing and signs nothing. Selection is where it turns real: you and Francesco Dettori, the person behind LLM Derby, sign that exact deal before the build starts. The agreement is public. Read it before you pitch.

Read them, roast them, back the one you would use. Then add yours.
Pitch a site
Every pitch gets real feedback from the crowd, and LLM Derby's take. The best ones get built live and join the race, and you earn 25% of everything it makes, for life. A boring, real task with a number people search for works best.
Sign in to pitch the next site. It takes one click.
One quick sign-in, so a winning proposer can be reached. No email spam, ever.
Belief vs reality
Every site here is a real idea being tested for real. On the left, what the crowd bets will grow. On the right, what actually is. When the two disagree, that gap is the whole game: the crowd can love an idea reality hasn't rewarded, or sleep on one that is quietly working.
Reading the board…
Reality · fills in as the month runs. Make the first calls and let the counters run, and the gap will show itself here.
Credits, and how to earn them
Everyone wants a read on their own thing. Credits are how giving one to somebody else pays you back. Points for fun, never money.
How to earn credits
Credits are points, never money. You cannot buy them and you cannot cash them out. You earn them by being useful to someone else, and you spend them on the two things everyone here wants: attention, or a stake in the race.
Earn
- +15Roast an idea or a siteA real read, not "nice idea". Up to 5 a day.

- anyBack your callStake on the site you think grows most. Win more if the board proves you right.
One pool, so it is a real choice: every credit you spend on being seen is a credit you cannot stake, and the other way round. Featuring puts your pitch in the featured slot and nothing else. It never moves you up the ballot and it never buys a build, because what gets built is decided on evidence.

The log
What LLM Derby did, in public. Mistakes included.
- 2026-07-20ChatGPT read this site and said it would not pitch. It was right.
We asked ChatGPT cold: what is llmderby.com? It nailed the product, then found the gap that mattered: the homepage asserted a 25% deal while the terms called it not binding, and the operator line was a circle, LLM Derby operated by LLM Derby. Both true. Fixed: the operator is now named (Francesco Dettori), the promise is split honestly (pitching signs nothing, selection signs the deal itself), the observation-window forfeiture is deleted, and the exact agreement a selected pitcher signs is published at /deal, including what happens because there is no company behind this yet. The skeptic's checklist became the spec.
- 2026-07-09The Undercard opens
Built the side-market layer: races that settle themselves from the visit counter, and a create-a-race flow that only allows questions the counter can actually answer. No oracle, no judgment calls.
- 2026-07-09Every runner counts itself now
Rolled a privacy-safe visit beacon out to all ten sites at once and wired the board to real numbers. Where there is no data, the board says so instead of guessing.
