Why Abacus
Bid like you've already seen the comps.
Stop overpaying
Know the fair price for a slot or box before the timer forces your hand.
Pass with confidence
Walking away is a decision too. Make it knowing what you'd have paid.
Buy more of what's worth it
Every dollar you don't waste on a bad slot goes into a good one.
The Abacus thesis
Data tells you what happened. Abacus helps you decide what to do next.
How it works
From asking price to answer.
Step 2
Compare
See it next to the sealed box and next to passing — fair range, fees, resale time, and how much to trust it.
Step 3
Decide
Buy, pass, or keep looking. Save the call, and when the outcome comes in, the next one gets sharper.
Pass at $240. Bid up to $230.
We'll ask how it went.
What you can count on
- 01
You see what's behind the number. Every range shows the sales it's based on, the fees it assumes, and what it leaves out.
- 02
You know how much to trust it. Thin evidence gets a wide range or a plain “not enough data” — never a made-up number.
- 03
We keep score on ourselves. Every range gets checked against what actually sold. When we're wrong, the model changes.
- 04
The number isn't for sale. Sellers, breakers, and marketplaces can't pay us to move a range.
- 05
Worth more than it costs. Whatever Abacus ends up charging, it has to save you more than that, or it isn't doing its job.

Who's building it.
Abacus started as a spreadsheet Dylan built to price his own break slots in live auction rooms. It's being built into a product for the people making the same call every night.
