The Problem
Buyers have access to agents. They are already shopping. Today an agent reaches your store the only way it can: scraping listings of uncertain freshness, dropping emails into your CRM, negotiating against your auto-responder. To your team it looks like a customer. It is an agent working a customer’s parameters. Meeting it well takes a different system. That is an efficiency problem and a success problem, and it is why The ARM exists.
The Category
The Agent Relationship Manager (ARM) is the system that makes a dealership transactable by AI agents, on the dealer’s terms. Real inventory. A real price built from the dealer’s price parameters. A way to move the deal forward. The reference implementation has been live at Mark Miller Subaru since April 2026.
Five Seconds. One Conversation.Live since Apr 2026
This is what a lead looks like when an agent builds it. A web form is terminal. A thread is alive.
Inside the parameters, nothing waits.
Why The ARM Exists
Three things are true simultaneously right now.
“The future is already here. It just is not evenly distributed.”
William Gibson · He was not talking about automotive retail. But he could have been.
The Buyer Has Access to an Agent
Any buyer can now put an agent to work. It transacts without fatigue, without emotion, with full data transparency, and it works the parameters the buyer set. For less than the cost of a dinner. Or built in the time it takes to make one.
The Channel Is Not Built Yet
The agent gets what the store offers it in machine-readable form. Most stores offer nothing yet. So the agent scrapes listings it cannot verify, its emails land in the CRM, and it argues with a template or a member of your team. The buyer waits. The agent guesses. The dealer chases.
The Store Cannot See It
The agent lead enters the CRM looking like a customer. A salesperson picks it up and tries to build rapport. The agent is not there to be known. And when a sale closes, no true trail traces back to the conversation that produced it in any effective, manageable way. The channel is real, growing, and invisible.
The fork in the road.
Picture a fork in the road at the front of every dealer’s pipeline.
Human Leads
Into the CRM and the process the store already runs for people.
Agent Leads
Into The ARM. Not to be fought. To transact.
Same dealer. Same inventory. Same team. Two lanes, because the two leads want different things.
The Definition
Not a feature. Infrastructure.
At its core, The ARM is the ability for agents to interact with each other without friction. Think of it as a highway. We are building the road so the buyer’s agent and the seller’s systems can meet, transact, and move at machine speed.
On that road, an agent can:
Nothing about the store’s process changes on day one. But the lead that arrives is categorically better than a form fill. It arrives as a nearly finished deal, not a name to chase. Trade structured. Payment estimated. Vehicle held.
The rails carry the deal. The parameters govern it. The dealer set them in advance.
The Doctrine
Five rules.
No Fabricated Numbers
Every price is itemized and computed, never generated. The AI reads tools. It does not improvise a price. Ever.
Consent on Every Handoff
Nothing moves from machine to human without structured consent. The buyer decides when the deal becomes a lead.
The Data Tells the Truth
Freshness is published only when a sync provably succeeded. An unknown odometer stays unknown, never zero. And if a store’s data feed fails, the system flags the failure and holds the last verified state. It never tells an agent the lot is empty when the truth is the feed broke.
The Audit Trail Is the Product
Every conversation is a numbered thread. Every quote, hold, and handoff lives on it, with provenance. One record. Zero disputes about what happened. And the trail compounds: it is the data we learn from to improve every future interaction.
The Parameters Are the Authorization
The dealer sets the parameters in advance. Inside them, the deal runs without stopping, from quote through financing to delivery, as far as the dealer’s tech stack can carry it. Only a deal outside the parameters waits for an answer. Authorization is the constant. Waiting is not.
Trust
It runs both ways.
A deal is a mutual agreement between a buyer and a seller. Agentic commerce does not change that. The ARM does not control the buyer’s agent. It guides the interaction, the way good retail always has: openness first, commitment when both sides are ready.
Reputation is earned in both directions. Good behavior earns reach. Bad behavior earns regulation, applied per agent, not per channel. The ARM gives both sides the ability to manage that. An email inbox never could.
What We Build
Five products. One category.
The ARM.
The Agent Relationship Manager. The rails that make a store transactable, and the vantage point to understand and manage the agentic relationship as agentic commerce takes shape. Live at Mark Miller Subaru.
The Hound.
The first public-site agent detector. Every session scored. A measurable share of dealer traffic is already AI. Most stores can’t see it. The Hound can.
Jennifer.
The confidence engine. Buyer-side validation built for honest dealers. She gives the buyer confidence and the honest dealer the credit they earned.
DMC-12.
The open, MIT-licensed protocol for agent transactions. The future of standardizing how agents communicate. Agents discover inventory, negotiate within dealer rules, and transact at machine speed.
GEO.
When customers ask AI, be the answer. Score your store’s AI visibility with the live GEO scorecard.
One architecture. Any industry.
The rails are not a car tool. The same architecture makes any business transactable by agents: real estate, healthcare, legal, financial services. Anywhere commerce happens, agents are arriving, and the pattern transfers. Automotive is first. It is not only.
In Production
This is not a whiteboard.
The concept behind the whole experiment is simple: agentic commerce without friction. Any buyer, working through an agent, moving toward a vehicle without the drag the process carries today. The Uber Eats of the car business, running on a real lot.
An AI-transactable inventory service has run in production at Mark Miller Subaru since April 2026. Real quotes. Real holds. Real handoffs. A complete audit trail across MCP, A2A, and UCP.
We started with CarEdge because they are the current experts in agentic commerce between car buyers and sellers. We hired them to shop our own store and watched a machine transact with our own sales floor. Then we built the lane it should have had.
The Invisible Channel
You have AI sales right now. You just can’t see them.
A percentage of dealer traffic is already AI. Some of those shoppers buy. Today, no store can tell you which sales those were. The conversation happened in an inbox, the deal closed on the floor, and the connection died in between.
The ARM keeps the connection. The conversation is a thread. The held VIN is on it. The handoff carries it forward. When the deal closes, it traces back to the conversation that produced it. Agent volume. Close rate. Gross by channel. A line on your report that has never existed before.
Every dealer picks this up at their own speed. Some route the agent lead into the CRM they already run. Stores with digital retailing tools can carry the buyer’s agent through the entire process, up to delivery and a completed transaction, inside the parameters the dealer set. Same rails. The dealer chooses how far to ride them.
You cannot manage what you cannot measure. This channel has never been measured. Now it is.
The Standard
The rubric is public.
Ten criteria define what qualifies as an ARM. Detection, deployment, enforcement, routing, reporting, memory, forecast. The full rubric is the canonical reference. Use it to evaluate a product. Use it to build one.
Are you building this? We want to hear from you. We want to build with you. The category is forming and the rubric is open. Tell us what you are building and where you think this goes.
The Path Forward
Five ways to move.
Get On the Rails
What runs at Mark Miller Subaru is a pattern, not a one-off. The next store does not build any of this from scratch. The work has been done. chris@thearm.ai
Transact, Don’t Scrape
Stop emailing inboxes. Real inventory, real out-the-door prices, holds on real VINs, and deals that arrive attributed. Known agents are warm leads. Unknown agents are not. chris@thearm.ai
Integrate Or Adopt
The ARM is infrastructure. CRMs, DMSes, digital retailing tools, and inventory platforms that speak DMC-12 become more valuable to their dealers. The rubric is open. The protocol is open. chris@thearm.ai
Bring Us Your Ideas
This is in development and moving fast, and we have not solved the whole problem. We need buyer’s agents and seller’s agents pushing on this with us. The future of agentic commerce in automotive needs a standard, named and adopted. We would rather build it with the industry than for it. chris@thearm.ai

Straight Answers
Questions people actually ask.
What is an ARM?
The Agent Relationship Manager: the software layer that makes a company transactable by AI agents and manages those relationships, the way a CRM manages relationships with customers. The full definition and rubric live at /rubric.
Is this a product pitch?
It is a standard with a working proof. The dmc-12 protocol is MIT-licensed, the rubric is public, and the reference implementation is documented at /arm. If you want to build against it, adopt it, or beat it, everything you need is public.
Can my AI agent transact with a store right now?
Yes. Copy the MCP endpoint from dmc-12.ai into Claude, ChatGPT, Gemini, or your own agent and shop live inventory at the reference deployment, Mark Miller Subaru. No account required.
Does this only work for car dealerships?
No. Automotive is first, not only. The same architecture makes any business transactable by agents: real estate, healthcare, legal, financial services. The pattern transfers wherever commerce happens. See where it goes.
What happens when a deal reaches the dealer?
The deal is delivered whole into the dealer’s tech stack, in the format the store already consumes: quote itemized, trade valued, payment estimated, vehicle held. Inside the parameters the dealer set in advance, nothing waits.
Official Definition
The layer for the agent era.
Agent Relationship Management (ARM) is the software layer that makes a company transactable by AI agents, and the layer through which a company understands how agents interact, so it can prepare for the future of agentic commerce, the way CRM governs a company’s relationships with its customers.
CRM orchestrates customers.
ARM orchestrates the agents that orchestrate customers.
“Every dealer eventually had a website. Every dealer will eventually have rails. The category is named. The doctrine is written. The first store is live.”
