What is a Seedrun?

A Seedrun is a page for an idea that is not built yet. A founder made it in Seedrun, a card game about startup ideas, to find out whether real people want the thing before spending months building it. The page stays up while a clock runs. If enough people sign up before it runs out, the founder builds it.

Because nothing on a Seedrun page exists yet, and you should know that before you sign up. You are raising your hand for something that might be built later. Founders cannot remove the notice.

You give your email, and if you like, what you do (for example "line cook in Denver"). Then you confirm your email, and your signup counts toward the goal and adds time to the clock. The founder may email you about this idea. If you tick the box, your role (never your name or email) can appear on the page as "A line cook in Denver joined".

The form says exactly what you agree to: that the founder may email you about this idea, and that Seedrun processes the signup for them. Your name and email are never shown on the page. To have a signup removed, write to hello@seedrun.app.

The person named on the page by their Seedrun handle. They made the idea card and the page, and they are the one who will build it and email you. Seedrun is the game and the platform they used; Seedrun does not build the ideas.

Some founders ask for money to see whether people will pay. A pledge saves your card and charges it only if the run reaches its goal before the clock runs out; if it misses, nothing is charged. A deposit is charged right away and refunded automatically if the run misses its goal. Every paid run shows its price, its refund policy and a delivery date next to the form. Many runs are free: you reserve a spot and pay nothing.

If a run misses its goal, pledges are never charged and deposits are refunded automatically when the clock ends. If a run reaches its goal, the founder is the seller: they owe you the product by the delivery date, or a refund under the policy on the page. Payments go straight to the founder through Stripe. Seedrun never holds the money.

Yes. The count only includes people who confirmed their email or completed a pledge or deposit. A founder has no way to add or fake signups.

The page shows the result, including a miss: the final count, which goals were hit, and whether the idea is being built. You can ask to be told once if it comes back.

Every run starts with a countdown the founder picks, 7 days by default. Each confirmed signup adds time to it. Seedrun's server keeps the official end time, and the page counts down to it.

It depends on how early you join. Near the start of a run a signup adds about 6 hours. The amount holds high for a while, then falls faster toward the end of the run's set length, down to 5 minutes. After that, every signup adds 5 minutes.

Yes. A signup through a friend's share link adds a quarter more time (1.25 times). A pledge or deposit adds three times as much, and both together add 3.25 times. Only confirmed signups count, so an unconfirmed email adds nothing.

No. The clock can stretch to twice the run's set length and no further. A 7-day run can last 14 days at most. Once a clock is at its limit, the page says so, and new signups still count toward the goal.

They are the stages an idea climbs on real evidence. Seed: the page is live. Sprout: strangers want it, shown by signups from the people it is for. Rooted: strangers paid, through pledges or deposits.

Play Seedrun, the free card game. Your ideas become cards, and other players judge them in blind battles in the Pit. When one looks worth testing, plant it as a seed: it leaves your deck and becomes a public page like the ones here.

You choose, from 3 to 60 days. Signups can stretch it to twice that length, never more.

Putting up a run is free. If you ask for pledges or deposits, the money goes to your own Stripe account, not to Seedrun. You are the seller, so you set the refund policy and the delivery date, and both are shown next to the form.

Only if you choose to list it. Unlisted runs still have their own page and link; they just do not appear in the list here.
