Is this meaningfully different from those customers using bankrate.com to find the highest yielding one year CD?

Yes, it’s quite different. Bankrate doesn’t aggregate customers and put them in a single-buyer bargaining pool. Customer aggregation would basically tell banks “if you show us your best possible rate, you will potentially gain hundreds customers instantaneously. Our customers have already pre-committed to whichever bank offers the highest rate.” That should result in rates going as high as a bank could possibly offer. Would you use such a service?

I don't know, it seems to me like a search engine does aggregate customers. Aggregate means to put together, and having an easy way to search for the highest rate focuses the people who want that on whoever is at the top. Since there is predictably a pool of people like that, having them come together in some more explicit way wouldn't seem to add any value.

The highest rates are a lot higher than normal, (like 2%) and from banks that you wouldn't normally think of, so I don't understand where anything additional comes from. It seems like a projected free lunch from unspecified sources.

Search engines aggregate the intent, the app can actually move the funds. Big difference.

If bundling the assets of a hundred or a thousand people made a difference, then entities with millions would be able to get the same deal already. But 1 year treasuries only pay like 1.5%, right? Who is getting >2% risk free?

I don't see where the there is.

The aggregated of demand, ability to move funds effectively turn the underlying accounts into commodities that can compete based on that one feature (yield).

The other difference is that this money is fluid unlike a CD. With enough data the app should be able to predict how much of the aggregate funds would remain static in the account over what periods of time though. So banks could offer rates based on that aggregate guidance.

If you can't get a higher rate with say a billion dollars belonging to one decision maker, how would people with much less improve their returns by coordinating?

What you call the money being "fluid" would tend to make it less valuable than CD deposits.
