AI Agents Are Shopping for You. Who’s Selling to Them?
Introducing Spangle Halo, an AI merchant agent that works for retailers.
AI agents are starting to change how people shop.
Instead of browsing multiple websites, comparing products, and navigating checkout, customers can ask their personal AI agents to do the work.
These agents understand what customers want. They can find products, compare options, and help make purchasing decisions.
But there’s another side to every purchase.
Who is working for the retailer?
Shopping agents are only half the story
Retailers have spent decades learning how to win customers.
They understand their products and what drives demand. They know what’s selling, what customers respond to, and where the margins are.
That intelligence shapes merchandising decisions every day.
But what happens when the customer is no longer shopping directly on the retailer’s website?
The customer’s AI agent is making decisions on their behalf. The retailer still needs to decide what to offer, how to merchandise it, and how to earn the purchase.
Making a product catalog available to AI agents doesn’t solve that problem.
Connecting to an agent is not the same as knowing how to win its business.
Introducing Spangle Halo
Today, we’re introducing Spangle Halo, an AI merchant agent built to work for retailers.
Spangle Halo doesn’t start cold when a shopping agent arrives.
It’s powered by Spangle’s brand-specific intelligence, which continuously learns what customers are looking for across AI, search, social, and other channels. It combines that demand intelligence with the retailer’s own products, inventory, performance, economics, and commercial priorities.
Every agent interaction is informed by what Spangle has already learned about winning customers for that specific brand.
And every interaction and its outcomes feed back into that intelligence, improving future decisions.
The retailer sets the strategy and boundaries. Spangle Halo uses that intelligence to make merchandising and selling decisions on its behalf.
Here’s what that looks like.
Look at what’s happening on the retailer’s side
In the video, Maya is looking for an outfit for an interview.
Her personal AI agent understands her preferences and what she’s trying to accomplish.
Spangle Halo has a different job.
It understands the retailer’s business.
Spangle Halo considers inventory, trends, product performance, and commercial priorities to decide which outfit the retailer should put forward.
This isn’t simply matching products to Maya’s preferences. It’s a merchandising decision about how the retailer can best serve Maya and win her purchase.
Then Spangle Halo recommends gold hoops to complete the look, increasing the value of the basket.
It helps address delivery and returns questions so Maya can complete her purchase with confidence.
Maya has intelligence working for her. The retailer has intelligence working for its business.
Connecting to shopping agents is only the beginning
The infrastructure for agentic commerce is taking shape.
Protocols such as UCP and MCP are making it easier for shopping agents to interact with retailers. Product discovery, checkout, and fulfillment are becoming accessible through these new interfaces.
That’s necessary progress.
But it raises a more important question for retailers.
When an AI agent arrives ready to buy, what intelligence decides how your brand should respond?
A catalog can tell the agent what’s available.
A commerce platform can help complete the transaction.
But deciding what to put forward, how to merchandise it, and how to win that customer requires an understanding of the retailer’s business.
Spangle Halo brings that intelligence into the interaction.
It supports UCP, MCP, and browser-based interactions, but connectivity is only the starting point.
The goal isn’t simply to make a retailer’s products available to shopping agents. It’s to help the retailer compete for the customer those agents represent.
Every retailer will need intelligence on its side
The interface to commerce is changing.
Customers will have AI agents helping them decide what to buy. Some of those decisions will happen before a customer ever visits a retailer’s website.
But the retailer’s responsibility hasn’t changed.
It still needs to understand demand and run a profitable business.
The difference is where those decisions need to happen.
We’ve been building Spangle around a simple belief. Retailers need intelligence that understands their business and works on their behalf wherever shopping decisions happen.
Spangle Halo brings that intelligence into conversations with shopping agents.
Every retailer will need intelligence working on its side as more shopping decisions move to AI agents.
Your customers have AI agents.
Now your brand can have one too.
