Only build what people already want. Yours or ours.

Bring your idea, or take one our engine found in the market. Either way we go and ask real strangers before anyone builds.

If it passes 150, we build it. If it does not, you have lost ten days instead of a year.
Almost everyone does this in the wrong order.
Have the idea. Spend a year building it. Launch it. Find out what people actually wanted. We swap the last two steps around, so the finding out happens while it is still cheap to change your mind.
First

We read the market every week and look for the gap.

Not one source and not one kind of signal. Where several of them point at the same missing thing, there is usually a business waiting.

What people say
r/dogs · u/two_cats_one_bag · 4d

Every trip starts with two nights of texting friends to find someone to feed the cat.

Finding someone I trust is the hard part

The booking works fine. Knowing who walks into my house does not.

Then

A small company that exists for ten days.

It gets a name, a website and advertising. For those ten days it looks completely real to anyone who finds it, because to them it is.

For anyone who has a pet and a plane to catch

Someone you already trust feeds the cat.

Pick a neighbour, a friend or your sister. We handle the keys, the schedule and the check-in photos, so you stop texting five people the night before you leave.

On day ten

You either beat the number or you did not.

Before anything goes live we agree one number with you: how many people would have to put their hand up for this to be worth your year. It does not move afterwards.

If it passes

We can build it, usually in a week.

Only if you want it. A full working product with payments, on your own domain, and you own the code, the domain and the accounts. What it costs depends on the project.

If it does not

The idea dies.

On day ten, not a year and a salary later. Most ideas end here, and that is the whole point of doing it in this order.

The board

Part of it is open. The rest needs a seat.

Anyone can look. Members see every idea, and can take one.
