Spots — guaranteed, never oversold
Registration that sells out in minutes.
And never oversells.
OK I'M IN is registration for any event with a hard cap — take entries first-come or run a lottery. We never oversell a single spot. If we do, we refund every fee you paid us. And for lotteries, the draw is one anyone can verify.

One platform — not eleven tabs
Everything your race needs. One login.
Most directors run their event off a pile of tools that don't talk to each other. OK I'M IN is the all-in-one: registration, the fair draw, your volunteers, payments, waivers, and race day — in one place, on one login.

The guarantee
Sell spot #201, and you don't pay us a dime.
“That's the deal.”
Capacity is a hard number, not a hopeful one. We make overselling impossible by design — every spot can have only one owner, and we log the exact second each is taken. And we back it with our own money: if we ever sell one spot past your cap, we refund every fee you paid us for that event. The guarantee is ours, not yours.

How it works
Four steps. No refresh-at-7am roulette.
Entering takes a minute. Then the open (or the draw), the claim window, and an honest checkout do the rest.
-
Step 01
Enter
A short form. For lotteries, entering early earns nothing extra and entering late costs nothing.
-
Step 02
The open, or the draw
First-come? The gate opens at the exact second — no early peeking. Lottery? The draw is locked to a fingerprint published the day before, and names reveal live.
-
Step 03
Claim your spot
Get in, and your spot is held while you check out. The hold survives a declined card — the card said no, your spot didn't.
-
Step 04
Honest checkout
Itemized pricing, fees shown up front, no surprises. On-screen confirmation, then a receipt by email.
Fairness — in public
Don't trust us. Check us.
A skeptical runner should be able to trust the draw in thirty seconds — not because we're nice, but because the math is in their hands.
-
01
Lock the rules first
The day before, we post a short code built from the draw's rules — its fingerprint. Change a rule and the code changes.
-
02
Then reveal
Then we draw the seed — a random number nobody controls — and reveal it. The code from before proves nothing changed.
-
03
Replay it yourself
Re-run the same shuffle on your own phone and watch it land on the same list. Results are public, with names removed.

Built for the stampede
A million people can show up. Exactly the right number get in.
Zero oversell holds up under any crowd because of how the engine is built. It never leans on one shared counter that could buckle when everyone shows up at once.
Here's the plan. We'll simulate a million people rushing a 70,000-ticket event, in public. We'll prove exactly 70,000 sell, zero oversold, in fair order. We'll publish the speed numbers and the raw logs. We haven't run it yet — when we do, the results live here.
For race directors
Set fair rules. Watch honest numbers.
- Cap any event and never oversell it — first-come or by lottery.
- Write lottery rules in plain sentences — volunteer credit, past finishes, never-started bonus, charity bibs, reserved entries.
- Run the open or the draw and the claim window on autopilot, with a live ops dashboard of honest numbers.
- Hand every entrant a provably fair result they can verify themselves — fewer angry emails on draw day.
- You carry no risk for oversell. If we ever oversell, we refund every fee you paid us — the guarantee is ours, not yours.
Questions, answered straight
No fine print games.
What does “never oversells” actually mean?
Capacity is a hard number, not a hopeful one. We make overselling impossible by design, because each spot can have only one owner. And we back it with our own money: if we ever sell one spot past your cap, we refund every fee you paid us for that event.
How is the lottery provably fair?
We post a short code (a fingerprint) of the draw the day before the random number — the seed — exists. The seed is then drawn from a public source nobody controls and revealed. You can re-run the exact shuffle on your own phone and land on the same result.
What does it cost runners?
You pay the registration price the director sets, plus any fees shown itemized at checkout. Nothing is hidden — what you see at checkout is what you pay. Entering a lottery is free.
When am I charged?
Only when you claim a spot and complete checkout. Entering a lottery costs nothing, and a declined card keeps your hold while you try again.
What kinds of events is this for?
Any event with a hard cap that sells out fast — trail and road races, festivals, workshops, drops, and ticketed events. Take entries first-come-first-served or run a lottery; the zero-oversell guarantee applies either way.
How do you handle the traffic spike at open?
A virtual waiting room holds the crowd at the gate. It lets people in to claim a spot at a steady pace. So the count stays honest, no matter how many show up at once.
