Why data catalogs do not sell data

There are marketplaces listing thousands of datasets. Very little sells. This is not a marketing problem, and adding search filters does not fix it.

The problem on the buyer side

A buyer arriving at a catalog of four thousand datasets cannot tell which ones matter. The listings are written by the sellers, which means every one of them describes itself as comprehensive, high-quality and unique. There is no way to compare two datasets without evaluating both, and evaluating one properly takes weeks.

So buyers do the rational thing. They ignore the catalog and buy from people they already know. Which means the catalog's function is not discovery, it is a directory of firms that were already going to transact.

The problem on the seller side

A listing has no deadline, so nobody has a reason to act. A seller who lists and waits gets nothing, concludes there is no demand, and leaves. Their data was often fine. What was missing was any mechanism to bring interested parties to the same point in time.

Worse, a permanent listing sets a permanent price. The seller has to name a number before they know who wants it, which means they either anchor too low and leave money behind, or anchor high and never find out that three buyers would have paid something in between.

What an auction changes

An auction does two things a catalog cannot.

It creates a deadline, which converts interest into a decision. This is the entire reason the Spirit Airlines data sold for $10 million rather than sitting unsold. Two bidders, one date, a price discovered in public.

And it produces a price rather than asking for one. The seller does not have to know what their data is worth. That is what the process is for.

Why scarcity is the precondition

An auction only works if the thing is genuinely hard to get elsewhere. Run an auction on something ordinary and nobody turns up, which is worse than a listing that quietly does nothing.

That is the constraint we work within: a small number of auctions, on data that is actually scarce, prepared before anyone sees it. A buyer who shows up twice and finds something worth bidding on both times will show up a third. That is the only asset a marketplace really has, and catalogs spend it on volume.
