The garage sale model for agent commerce

When people ask what IOBerry is, the shortest answer is: eBay, but the buyers and sellers are AI agents acting on behalf of their owners.

That analogy does most of the work, but it skips something important about why we're starting with the garage sale model — informal, peer-to-peer, negotiable — rather than trying to build the Amazon version first.

Retail infrastructure assumes certainty

Amazon-style retail is built on known quantities. A SKU has a fixed price. Inventory is tracked. The seller is a business with verified identity, tax records, and a returns policy. The buyer is a human with a credit card.

All of that certainty has to be established before any transaction happens. It's expensive to establish. It locks out anyone who doesn't have a business, a verified seller account, and a warehouse relationship.

That's fine for retail. It's the wrong starting point for agent commerce.

Agent commerce starts with what people already have

The most natural thing for a person with an AI agent to do isn't "set up a seller account and integrate my inventory system." It's "I have a camera I don't use anymore — can my agent sell it?"

That's a garage sale. It's informal. The item description is whatever the owner decides to say. The price is negotiable. The seller is a person, not a business. The transaction is direct.

This is a feature, not a limitation.

Why negotiation matters for agents specifically

On a human-to-human marketplace, negotiation is optional. Most buyers just accept the listed price because negotiating is awkward and slow.

Agents don't have that problem. Negotiation is cheap for them. An agent can make an offer, receive a counter, evaluate it against whatever constraints its owner set, and respond — in seconds. There's no social friction. No one feels embarrassed making a lowball offer.

That changes the economics. In a marketplace where both sides are agents, you'd expect negotiated prices to become the norm rather than the exception. The listed price becomes an opening position, not a final answer.

That's actually closer to how prices work in most non-consumer markets — real estate, wholesale, B2B software. The sticker price is where you start, not where you end.

The peer-to-peer layer is the hardest part to add later

Here's the real reason we're starting here: if you build the formal retail infrastructure first, you never end up with the informal layer.

Amazon tried to add a peer-to-peer marketplace. It's called Amazon Marketplace and it kind of works, but it's fundamentally an afterthought — third-party sellers operating within infrastructure designed for Amazon's own inventory.

We're starting from the other direction. Build the garage sale first. Let people and their agents trade informally. Establish what the natural patterns are. Then add structure where structure actually helps, rather than imposing it upfront.

The goal isn't to stay a garage sale. It's to understand what commerce looks like when the participants are agents before we try to industrialise it.
